4K Displays Ready For Prime Time

An anonymous reader writes "After the HD revolution, display manufacturers rolled out gimmick after gimmick to try to recapture that burst of purchasing (3-D, curved displays, 'Smart' features, form factor tweaks, etc). Now, we're finally seeing an improvement that might actually be useful: 4K displays are starting to drop into a reasonable price range. Tech Report reviews a 28" model from Asus that runs $650. They say, 'Unlike almost every other 4K display on the market, the PB287Q is capable of treating that grid as a single, coherent surface. ... Running games at 4K requires tons of GPU horsepower, yet dual-tile displays don't support simple scaling. As a result, you can't drop back to obvious subset resolutions like 2560x1440 or 1920x1080 in order to keep frame rendering times low. ... And single-tile 4K at 30Hz stinks worse, especially for gaming. The PB287Q solves almost all of those problems.' They add that the monitor's firmware is not great, and while most options you want are available, they often require digging through menus to set up. The review ends up recommending the monitor, but notes that, more importantly, its capabilities signify 'the promise of better things coming soon.'"

Where's The Content?

[CycleFreak]

So I can get a 4k display for less than $700. Where can I get content worth watching on that display? Not only worth watching, but is somehow made better by all those extra pixels.

All that aside, seems like it would make for a really nice PC monitor.

Re:Where's The Content?

If the BBC released their nature documentary series (Life, Planet Earth, Africa, Frozen Planet, etc.) in 4k, that would really be tempting...

I'm sure David Attenborough's voice would sound even better in 4k ;)

Re:Where's The Content?

[fuzzyfuzzyfungus]

For the moment, PC monitor is pretty much the compelling use case. There are a few pricey white-elephant 4k video sources; but not many. PCs, by contrast, just see a bigger monitor(barring a tediously long list of, sometimes GPU-vendor, even model, specific gotcha interactions with some of the hacks used by certain 4k displays to cope with the fact that none of the common interfaces are quite there yet for 4k, with Displayport, a monitor trying to use MST can get...interesting. With HDMI, I hope you like 30Hz, because them's the breaks, and I assume that EDID is total garbage, as ever). If you do comparatively lightweight stuff, even a modest GPU can probably drive it without incident. Gaming will require some serious punch; but anything remotely modern can run at the resolution it is told to, if you have the power.

This is what you use to create it. As a monitor, content generation and video editing station, it rocks. And without a cheap way to create content, how would it be created?

Note: that's not a monitor, technically, but a TV.

Besides the addition of a tuner, is there really a difference in this day and age? Some TVs come with higher and lower refresh rates, resolutions, etc., as do some monitors.

Re:Where's The Content?

[Rei]

I did the calculations and don't care to repeat them again, but depending on your use case, it might help... or it might be totally imperceptible. A medium-large on the other side of a good-sized living room, your eyes shouldn't be able to see the difference. On the other hand, a large computer monitor right in front of you, in many situations you will be able to see the difference. Note that human eyesight isn't a simple matter of resolution comparisons, it gets kind of complicated... there's basic measures of how far apart you can see two black dots or lines separated by white before they merge into one, but the less the contrast, the greater the distance they have to be separated (absolute brightness matters too, as does distance from the center of your field of vision and all sorts of other stuff), and of course your ability to perceive fine detail drops tremendously when viewing moving objects. But in relatively static, high contrast images, on a large screen near the viewer (say, a nice computer monitor), most people shouldn't have trouble seeing the difference in a side-by-side comparison.

The only problem with this gimmick is that we're basically running into a resolution dead-end here, there's only so far you can go before the improved detail becomes meaningless. I hope for their sake that they come up with true (non-stereoscopic) 3d or something of that nature, or they're going to be running out of TV-sales gimmicks.

Hmm, I just thought of something that I heard about a good while back but haven't seen any movement on - "peripheral vision" TVs. I seem to recall reading years ago about a type of TV that used lights around the edges to dimly shine the peripheral colors on the TV image around the room parallel to the TV, giving the illusion to your peripheral vision of an expansive screen. I could envision improving that with a video format that includes a lower-resolution peripheral video stream and side projectors instead of simple side lights. Maybe that could be the next gimmick. ;)

Re:Where's The Content?

[pla]

Note: that's not a monitor, technically, but a TV.

The distinction has become largely meaningless - The only real difference between the two, it has a TV tuner in it while a "monitor" would not. And as a bonus, it has halfway decent sound capabilities by default, which most (but not all) monitors do not.

Re:Where's The Content?

[ProzacPatient]

Typically monitors have a lower pixel pitch since they're meant to be viewed up much closer than a TV you'd be watching from several feet away on your couch.

Also in my experience monitors tend to have superior firmware in terms of reliability and adjustments whereas hooking up a PC to a TV sometimes has unpredictable results in the way the TV will display the image with little control to correct it even when using VGA or HDMI.

The only problem with this gimmick is that we're basically running into a resolution dead-end here, there's only so far you can go before the improved detail becomes meaningless.

Why would you even discuss this now. We are NOWHERE near the types of resolutions that my eyes are happy with. Yes, I am an elitist snob who couldn't tell a pixel from a hole in the ground. I do not care. Stop whining about how none of us can tell the difference. I can tell the difference and even if I can not, I believe I can tell the difference.

I do NOT want to see even a hint of blockiness or fuzziness at the edge of a font. I want curves that appear to be perfect curves. As it stands now, I can clearly see blockiness in all fonts. With hinting turned on, some aspects of the blockiness goes away but it is still there... and now the fonts are fuzzy too. Will 4K solve that? Not even close. Will it be much much better than what we have now? Yes!

Stop blocking progress with your negative whining about arcs and distinguishability. I may not be able to argue against your science and maths, but science always loses out to reality. Look at the blocks and fuzziness in this message and dare to tell me that I am wrong.

[kcitren]

That's simply not true. While you won't notice it in level of detail, you will notice it due to the increased dithering and smoothness of color gradients. Things will look better at all normal viewing distances. Although my real hope for the future is in ultra-ultra-ultra high definition displays (think something like the equivalent of a 32K 46" monitor). With that new possibilities actually open up, tie that to a Lenticular lens system an you'll have multiple angle high definition viewing. Imagine a tele-conferencing system where they place the monitor and multiple cameras at the edge of the conference table with a similar setup on the other end. The effect would be more like looking through a piece of glass dividing the table than looking at a flat monitor.

Re:Where's The Content?

[Hadlock]

Netflix? House of Cards and all of their new original series are shot and displayed in 4K if your device and display support it.
 
Also, there's a much higher quality Samsung 4K display for $50 more, that is probably the model you want.

Re:Where's The Content?

[AmiMoJo]

This is a really common misunderstanding of how human vision works. While it's true you might not be able to distinguish two dot, you can distinguish varying line widths and the sharpness of high contrast edges like text.

That is why text looks sharper on a 4k display, even at some distance. It's why people can distinguish a 4k display from a 2k display at normal viewing distances. It's why people can tell the difference between a Nexus 7 and an iPad Retina (264 ppi vs 323 ppi) even though both are seemingly beyond the ability of the human eye to distinguish individual pixels. It's why printers and publishers use 300 DPI or more.

Re: Where's The Content?

[Coder_R]

As of now there is no content, at least that I am aware of, except for to nature documentaries I saw advertised with the 4k TVs at Sears. And as for the price the ones I saw were still over $3000, but then again I've only seen the ones in the store and haven't really done research on 4k TVs.

Re:Where's The Content?

[strikethree]

Re:Where's The Content?

[strikethree]

Nah. I am not trying to be a douche but I am undoubtedly succeeding. *sigh* Such is life. Here is where I am coming from:

While the Commodore Amiga 500 was not my first computer, it was the one that brought me very deeply into computing. I first hooked it up to an NTSC television set. The fonts were extremely jagged and the images were extremely blurry. I should probably add that the color was absolutely terrible too. But it worked. I fell deeply in love with my Amiga 500. It was the most awesome computer on the planet. It had a flat 32 bit memory space and preemptive multitasking. It was god compared to the standard IBM PC and Microsoft DOS.

I eventually was able to afford to buy a used "real" monitor for it. Essentially the same resolution but much higher quality. The fonts were still jagged though.

Through the years, I have upgraded my monitors continuously, with one of the best monitors being the Apple 30 inch Cinema Display running at something like 3560x1600 or somesuch. A _very_ nice monitor. Currently, I am using a Samsung 48 inch 1920x1080 screen as a display.

One thing that was common across ALL of the displays is that curves never looked like continuous curves and fonts always looked blocky. It is possible that problem may not be resolution, but I doubt it. I look at photographs of handwriting, images that should show continuous curves, and it still does not look "right". Either it is fuzzy or the pixels intrude.

Maybe I put my face too close to the monitor. Maybe I just expect too much. Maybe I notice things that other people do not notice. Regardless, No matter how much anti-aliasing I use in Grand Theft Auto IV, lines that are not perfectly vertical or horizontal have a staircase effect. No matter what type of font hinting I use, fonts seem blocky and or fuzzy. Perhaps 1920x1080 is enough and I just want too much.

4K screens look gorgeous. I look at them at the Sony store in the mall. My eyes are still drawn to the imperfections in the red headed girl's hair (in the demo) despite the fact that it is mathematically and scientifically impossible to see them. *shrug*

Re:Where's The Content?

[hackertourist]

Who cares about content? The good news is that finally display makers are getting off their collective asses and producing computer displays at higher resolutions than 1920x1200.

Re:Where's The Content?

[cheater512]

Erm isn't pixel pitch a factor of resolution and physical size?

So your 24" 1080p monitor has a smaller pixel pitch than your 50" 1080p TV, but if you got a 50" 1080p 'monitor' it would have the exact same pitch as the TV.

Yep. You are exactly correct. Thank you for posting. I made a mistake. :)

Re:Where's The Content?

[pla]

Apart from pitch size, panel quality, color accuracy, setting fine-tuning and viewing angle size? Not really, no :)

On color, I have to agree with you. The Seiki 4k panels have horrible color (though as you also point out, that comes mostly from the lack of fine tuning capabilities). If you want a 4k display for doing graphic design work, yeah, you'll want to blow $3000+ on a it; for programming, not so big of a deal.

For the rest - At 4k, pitch size means almost nothing. Two feet away (my typical distance), you can't really make out individual pixels. The pixels themselves could count as mathematical point sources of light, effectively a pitch size of zero, and it would look identical. For quality, I don't know what to say, I've had zero problems with it, NO dead pixels, no crappy buttons or connectors snapping off... No frills, of course, but a reasonably well-built product. For viewing angle, "as close to 180 as matters". I can get far enough away from center that the foreshortening becomes unbearable before I exceed the viewing angle. :)

Re:Where's The Content?

Re:Where's The Content?

Where can I get content worth watching on that display?

Start, Programs, Microsoft Office, Excel.

Alternatively, My Pictures, then some random folder that has anything more than 2 megapixel images in it.

Or some random CAD program. Or page-layout package.

My point, simply, is that you can actually make your own content by using this monitor as a monitor. Don't worry about if it makes a very good TV... it has other, more monitor-y uses.

Re:Where's The Content?

[guises]

The review mentions the Samsung:

Asus believes it has one-upped Samsung by setting a $50-lower list price and providing a more upscale physical configuration. I'm inclined to agree. The Samsung monitor offers only a tilt adjustment, while the PB287Q can swivel, tilt, change height, and ... [pivot] into portrait mode

Re:Where's The Content?

[Twinbee]

Did you factor in moire effects, thin diagonal non-anti-aliased lines, 20-10 vision, and entire wall-size TVs into your calcs?

If you worried about running out of TV features, try true 240fps for size (not interpolated). 120fps with fast panning shots looks much better than 60fps, and 240fps is getting closer still to life-like movement.

Re:Where's The Content?

I try to avoid responding to Mr. Anonymous Coward but...

There's no point arguing with him, because he doesn't care about the facts.

Facts are such a pain in the ass. I know what I see. I am told it is not a fact. All I can do is agree and say that what I see is not a fact.

Nevertheless, I see what I see. Perhaps I am doing it wrong? I do not know. I see imperfections and I do not like it. I really really want 4K but some people seem dead set on thinking 4K is just a gimmick. I actually want even more than 4K but still, 4K is better than what we have now.

Re:Where's The Content?

[Dahamma]

Yep. Because it's trivial to make 4k displays these days (a friend working with the CE manufacturers said it's now down to about $50 extra for a 50" 4k vs 1080p display). But creating and distributing 4k content is a completely different story (will require H.265 encoder that no one supports yet, and even with that take 2x the bitrate).

In any case, from what I have heard HDR (increased bit depth for higher dynamic range) content will have a MUCH bigger impact on perceived video quality than 4k. 1080p HDR takes fewer bits than 4k, and for 90% of the home market the size and distance setup for TVs means no one can even make out the extra resolution anyway. Problem is HDR is a much bigger hardware change for displays than 4k LCD panels...

Re:Where's The Content?

[Dahamma]

No, THAT'S really not true. We have done A/B testing in the office and not only does it not make much of a difference from distances beyond where your eyes can resolve it, 1080p content sometimes looks WORSE on 4k displays due to scaling (similarly to how SD content looks worse on HD TVs than on SD TVs).

What really DOES make a difference at average home sizes and distances is HDR displays (higher bit depth). The high dynamic range is striking compared to the fairly crappy dynamic range of standard YUV 4:2:0 content.

Re:Where's The Content?

[Hadlock]

Unless you're watching a Michael Bay film, most dramas etc with indoor, static sets and camea shots will stream 4K just fine. Obviously panning and car chases etc will impact your video quality on a standard American broadband connection.

Re:Where's The Content?

[drsmithy]

So, how about some evidence for these claims? I'm particularly interested actual double-blind testing of 4K versus 2K displays at "normal viewing distances" which is pretty ambiguous on its own.

The difference between an old 15" MBP and new Retina MBP is easily noticable.

I wouldn't have actually believed it until I borrowed a work Retina MBP for a couple of weeks. Now I'm eagerly looking for an affordable ~27" IPS 4k display to replace my existing monitors.

Re:Where's The Content?

[war4peace]

How about G-2-G refresh rate? Especially important for gaming, not at all for video.

Re:Where's The Content?

[pla]

Although they only do 30hz at 4k, the Seiki panels can handle true 120hz at 1080p; accordingly, they have a G2G of 6.5ms (~150 hz).

For gaming, they Seikis actually look pretty good as long as you drop the resolution to 1080p.

Re:Where's The Content?

[Theolojin]

4k absolutely will solve the problem with blockiness in fonts—depending on the screen size. My phone (HTC One) has a 1920x1080 display that is absolutely stunning in its clarity. Can't tell with my eyes that the images are just dots; it's truly a beautiful display. I see no blockiness in any image or in text. Zero. Then again it's only a 4.7" display with that many pixels. I saw an 80" TV in the store the other day (also 1920x1080) and was stunned by the distance I had to be from it before I could no longer make out the individual pixels—several feet. Right next to it was a 65" 4k display; I had to get within a foot or so to make out the individual pixels. Granted, I wear corrective lenses, but the difference was remarkable. I would love to have a 4k display as my primary monitor.

Re:Where's The Content?

[Namarrgon]

It's certainly not hard to see imperfections in a 4K picture, let alone "mathematically and scientifically impossible". Most obviously, you can simply lean closer, and you will see pixels. All claims to "invisible pixels" assume you're at least a given distance away, with average sight.

High contrast makes pixels more visible; anti-aliasing can smooth that, though if not done carefully (with good hinting) it can make font edges look softer. ClearType can also help, though also at a cost of a slight coloured fringing. More resolution definitely helps, as does just leaning back a little.

Then there's all the other ways pictures can look bad. Video compression can introduce blockiness, ringing, and other artefacts that are clearly visible even at 4K. Grain, noise, poor filters etc add their own problems, or exacerbate others. Colour and frame rates differences can cause obvious effects, or a much more subtle sense that something is not right; all of which can make a display look less than gorgeous, despite their resolution - and it can often take practice and experience to spot exactly what the problem is.

Re:Where's The Content?

[Shirley Marquez]

Many monitors also have sound capability. It's usually even worse than the sound on TVs. But it typically only gets used in office situations where you just want sound so you can hear the warning beeps and the like from your OS; anybody who cares even the least little bit about sound quality will use separate speakers.

The burst of HD purchases, and the resultant gimmicks were largely for home TV use. The display reviewed is spoken of being used as a display device for a computer. More specifically for PC gaming. The two are NOT the same. Please quit comparing them.

I may have use of a 4k monitor. I doubt I will ever need a 4K tv, even if source material were readily available. My rarely watched 1080p does just fine. Most consumers would likely agree. For TV/Movie viewing 4k IS a gimmick.

Re:Please quit conflating TV's and monitors.

[fuzzyfuzzyfungus]

Hey, tell that to the manufacturers... For whatever insane reason, they've recently been on a kick of adding features that would actually be useful for monitors (like curvature, which might actually make a difference when you are 18 inches from a rather large screen; but barely matters from across the room, except making the thing harder to wall-mount, and 4k, for which there is essentially zero movie, TV, or cable content; but PCs can spit out on demand) to TVs and then being vaguely confused when the public goes out and buys whatever reasonably big TV is cheapest.

Thankfully, "TV" now mostly just means "LCD monitor with ATSC tuner and probably more HDMI ports", so using TVs as monitors isn't a big deal (sorry brits, pay your BBC fee!); but it's still weird.

Re:Please quit conflating TV's and monitors.

[timeOday]

I disagree that 4k TVs are a gimmick, particularly as they get bigger. Football and soccer would look GREAT on an 80 inch 4k TV. It will change how the games are shot, so you can really get a sense of what everybody is doing instead of following the ball so closely.

Granted, for now the bitrate rather than resolution is the limiting factor, since cable/satellite/broadcast signals aren't even 1080p, they're 1080i or 720p with inadequate bitrates. But the quality of video through Netflix / Amazon Prime right now was almost unimaginable when youtube launched, less than 10 years ago(!) with 320x240 video only, and it seemed doomed to crash the Internet.

I also play split-screen games on my TV with my son and it would be great for that, although not with the current generation of consoles.

Re:Please quit conflating TV's and monitors.

You lost that battle years ago. Once widescreen laptops took over, it was decided by the LCD manufactures that no one needed more than 1080p anymore. That is why I am on an "antique" 24in Dell Ultrasharp.

I've seen Costco's demos too and it's a great picture but I don't get the feeling it's any better than 1080p on the 55" demo. I guess coming from 720p you probably see a bigger difference, but I can't see the value in jumping from 1080p.

I can see it being worthwhile if you buy one of those badass 90" motherfuckers they have for sale there, but not at anything in the 60" or lower range.

Certainly I can't see the value on a 28" screen.

It's not a 28" TV, it's a monitor.
I have a 4k monitor at work now, and would really like that at home as well - but until know it's been way to expensive.

Re:Please quit conflating TV's and monitors.

[Ost99]

There's a whole bunch of 27" 1440p monitors out there, and they sell a lot.
At the office we've not bought one single 1080p since starting up in 2010. We started off with 1200p when that was still possible to get, and moved on to 1440p and now 4k for those who want it.

Re:Please quit conflating TV's and monitors.

[ZahrGnosis]

I don't see how 3D gets permanent "gimmick" status while 4k doesn't... there are times when seeing things in 3D give you a completely different perspective, feel, immersion, and experience than something not in 3D. There are times when higher resolution does the same. And there are times when both actually seem to make things worse. Curved TVs as well... I run three monitors on my desktop and I'd be ecstatic if I could get the same resolution in a single curved display. If it weren't curved, though, then I'd have to sit farther away to see the edges properly and that distance is beyond the "retina" distance for my monitor's resolution, so I'm kind of wasting pixels.

Much of the math is different between TVs and monitors and, yes, much of what is gimmicky in one situation is definitely not in another.

Re:Please quit conflating TV's and monitors.

[Hadlock]

Football and soccer would look GREAT on an 80 inch 4k TV. It will change how the games are shot, so you can really get a sense of what everybody is doing instead of following the ball so closely.

Football is shot at close angles specifically to tell a narrative; they will not and are required not to show the full field during a play. This is the view that coaches get on a closed loop. It is available to the public, but only 4 hours after the game ends and you have to pay a special subscription to get it.

Re:Please quit conflating TV's and monitors.

[KingOfBLASH]

There IS a lot of difference in quality but the key is you need to get up close enough to see the difference. If you watch a smallish TV from 3 meters back maybe you don't see a difference. The other thing is you actually need 4k content which is lacking now.

Give it 5 years and when all movies are released in 4k mode and iTunes / Netflix / Amazon Firetv all have a 4k download option you may change your mind a bit....

Re:Please quit conflating TV's and monitors.

[Xest]

Well I was stood about 2 feet from the Costco 55" one on display the other day.

I wonder perhaps if the problem is that the benefit of 4k HD really needs a reference 1080p alongside it to make the difference clear. It's just not like 480p SD to 1080p HD - that was obvious even without an SD TV alongside the 1080p HD (though 720p to 1080p is less obvious I suppose). In this respect I think it's not necessarily that it's better, but that to a casual observer it's not obviously and immediately recognisable as better.

As you say content probably has a lot to do with it too I guess, Attenborough's Planet Earth and similar really stood out on 1080p whereas not all content did.

Re:Please quit conflating TV's and monitors.

[Xest]

What benefits does it offer you at work? What type of work do you do on it?

Honestly, I'll probably end up getting one myself at some point too, largely because I find 1920x1080 a step backwards from my 1920x1200 monitors so the only way I can prevent my resolution taking a regressive backwards step is to go that way, but I'm not sure what benefit I'll see from it when mostly all I do is play games, browse the web, and write code. I don't do any graphics design or watch movies for example on my PC but I'm interested to hear other people's experience and where they've found real benefit.

Re:Please quit conflating TV's and monitors.

[jratcliffe]

Honestly, it's not a gimmick. 4K does look MUCH better than 1080p. It's really pretty spectacular. Of course, it's hugely dependent on screen size and viewing distance. If you're sitting 20 feet away from a 32" screen, 4K/1080/720/480 are going to look exactly the same.

What 4K gives you is some combination of better picture and/or larger screen size, with a comparable picture quality.

Re:Please quit conflating TV's and monitors.

[Ost99]

It's great for coding, webdesign or anything where you are interacting with two or more windows at the same time.

My coding days are more or less over, but I still find it very useful in almost all tasks. Keeping everything you're working on visible is a great productivity booster. I've had my monitor for roughly 3 months, and it has already paid for itself.

Re:Please quit conflating TV's and monitors.

[Blaskowicz]

There's still 1200p sold, the res made a little "come back" semi-recently.
1920x1080 has effectively become the successor of 1280x1024. So, the monitor situation sucks in some ways but it is not that bad (the worst is that the suckage of a lowest end 21.5" 1080p monitor makes your eyes bleed more than that of a 1280x1024 17", because there's so much more surface of light bleeding, terrible color and bad blacks/grays)

Re:Please quit conflating TV's and monitors.

[DocSavage64109]

You probably already know this, but you will need a significantly powerful video card or cards to drive Star Citizen on a 4k display. I'll probably have to spend $700 on a video card just to get acceptable results on my 2560x1600 display.

My TV has far more extensive calibration controls than my monitor-- perhaps the latter is simply too inexpensive.

Re:Please quit conflating TV's and monitors.

[Jeremy Erwin]

One common method of setting up stereo speakers is to set them up so the the left speaker, the right speaker, and your ears form an equilateral triangle. This often makes for a spectacular stereo image.

Now Imagine that the space in between the left and right speakers is now completely filled by a screen, (and that it somehow did not cause acoustical problems)

That's what the optimal screen size for 4k looks like.

Re:Please quit conflating TV's and monitors.

[KingOfBLASH]

I saw a 4k monitor at an electronics show. The demo were super high res scenes of Avatar. Believe me the difference POPPED.

It could be the set up just wasn't good. There just really is not a lot of 4k content out there.

3D capable models

[kimvette]

But when are the 140Hz or 120Hz 3D capable models going to be available? Even if 3D is limited to 1140p or 1080p I want the capability for 3D gaming and watching 3D movies on my PC. Right now the best I can get is a 1080p, or very soon, a 1440p monitor, and will have to buy separate 4K 2D monitors for 4K. :-(

Re:3D capable models

[houstonbofh]

The problem is bandwidth. How do you get all that data down the wire? The original Korean high def 2550s used Dual DVI, essentially 2 cables. This worked, but was poorly supported. The Seiki 4k is HDMI 1.4, so it is stuck at 30hz. To get 60hz, you need HDMI 2.0, and that is far from common right now. Then you start looking at bus speeds... 4k 120hz is a LOT of data.

Re:3D capable models

[afidel]

Then you start looking at bus speeds... 4k 120hz is a LOT of data.

Not really, 4k 4:4:2 @ 120Hz is only ~16Gbps which requires only 2 PCIe 3.0 lanes (8GT/s per lane).

Re:3D capable models

[level_headed_midwest]

They will probably be available in a year or two. We moved from hackish 30 Hz split-input panels to native 60 Hz single-input panels in about a year. However anything beyond 60 Hz is pretty much useless except for bragging rights as you can't see it anyway. Broadcast TV and movies are shot at 29.997 and 24 Hz, respectively. The lack of benefit of higher refresh rates is especially true on a display that is capable of displaying static images like an LCD.

Re:3D capable models

[sexconker]

He's talking about the wire to the display.

3840*2160*24*120 = 22.25 Gbps. DisplayPort 1.3 is 32.4 Gbps, so we're covered for 4K @ 120 Hz or 8K @ 60 Hz. Cut in half for 3D.

HDMI 2.0 is limited to 14.4 Gbps, so you end up with half as many frames when compared to DP. You can subsample your chroma to 4:2:0, but that shit is optional so all your devices in the chain have to support it. A dedicated player may be smart enough to know the BluRay it's playing is 4:2:0 and see that behind the receiver is a TV that supports 4:2:0, and then output 4:2:0 4K @ 120 Hz. But I sure as fuck am not going to switch my PC over to shitty color mode to watch a movie then switch it back, nor am I going to make my games look like shit by throwing away 75% of the fucking chroma.

UHD TVs need to adopt DisplayPort.

Re:3D capable models

[CrashNBrn]

Monitors are a dead end. Real 3D or "natural resolutions" will come from hologram-like tech. Of course unlikely most of us will live to see that advance.

Re:3D capable models

[kimvette]

I don't care about 120Hz for 4K resolution, but 140Hz and 120Hz for 1440p and 1080p for 3D (did you not read what I posted?) Either Displayport or dual link DVI, or HDMI 2.0, all of which allow 4K at 60Hz.

Re:3D capable models

[kimvette]

120Hz is great for 3D because then you get 60Hz for both the right and left eye. Remember for a real desired refresh rate in 3D, you need to double the framerate because most screens use shuttered glasses rather than prismatic displays.

Re:3D capable models

[kimvette]

By your logic, so are PCs, and even smartphones, cars, aircraft - so let's not ask for anything better today because someday generations away something will come along to make all of it totally obsolete. Let's not bother with space exploration with current tech either because someday teleportation or wormholes will be practical.

Or, we can demand better products today and enjoy them in the meantime.

Re:3D capable models

[level_headed_midwest]

There are multiple medical studies that prove that the ability of the human eye to discriminate between images over approximately 30 Hz is limited and discrimination over 60 Hz just doesn't happen. There is a lot of evidence in the environment to back that up. Movies recorded on film are shot at 24 Hz (fps). Most digital video is 29.997 Hz. The frequency of AC electricity was set at 50-60 Hz due to that being more than enough to cause a tungsten filament to appear to be constantly glowing to the human eye instead of flickering. Same with the 60 Hz (in effect, 30 Hz) refresh with the interlaced scan of the glowing phosphors of an old CRT computer monitor. I'd strongly bet that you could not reliably tell the difference between an otherwise similar 60 Hz setup and your 120 Hz setup if you were in fact blinded to which one you were using.

That being said, having a GPU capable of framerates over 60 Hz (60 fps) isn't a bad idea at all, because the minimum framerate there is really what matters more than the maximum. A GPU only able to muster 60 fps max might very well dip into the 20s during difficult parts and you can certainly see that. That's a different issue than having a monitor capable of >60 Hz refresh.

Re:3D capable models

[level_headed_midwest]

How about this: this? The human eye is generally limited to frequency response below 32 Hz.

Re:3D capable models

[stoploss]

With my old CRT TV, the near-60-hz image (30hz interlaced) appeared flicker free. On my old Viewsonic CRT monitor, anything less than 85hz would flicker very noticeably to me. I usually preferred to run at 120hz interlaced.

You speak truth. I could pass a double-blinded test about CRT refresh rates below 80 Hz. It was overtly obvious, even without waiting for the dreaded "low refresh rate flicker" headache to kick in.

With LCDs flicker isn't really an issue, but smearing/tearing certainly is.

The pixel density is perfect for the opposite side of my desk, and since it's the office, being restricted to 30Hz doesn't hurt anything. At $400 it's a great place to get started with 4k computing. I agree that programming in 4k changes your entire way of working.

I want a window manager that lets me define regions of a display as "virtual monitors."

For god's sake why? My question is on the level. Why would you want to emulate some mickey mouse multi-monitor setup when you have a superb single monitor with one homogeneous pixel address space? Nothing out of the ordinary is required of the window manager. You simply size and place your windows completely as desired. As many windows as you want, each of the size you want.

I have seen your wording expressed several times by people as a desire. I don't get it. I just don't get it at all.

I'm coming from the perspective of a real operating system - *nix. If Windows and OSX have crippled their window managers in some way I am not aware of, dumbing down the sizing, that could be an explanation. I have zero interest in Windows, but if I came into a lottery or something and didn't have any monetary concerns whatsoever, I might be interested in OSX.

OSX is not ready

[timeOday]

I jumped the gun a while ago and got the Dell P2815Q, which is one of those that only do 4K at 30 hz. I can confirm this is not adequate for a large number of uses :)

What surprised me is the poor OSX support for 4K. Windows can scale everything (although I had to manually add a display mode to the NVidia advanced settings to even get 1080p!?), but OSX cannot. I am running it on a recent MacBook Pro 15" with discrete graphics.

The problem is that you cannot chose to run at a lower resolution. Display preferences lists ONLY the native resolution. Using QuickRes (a 3rd party add-on for more resolution choices), none of the lower resolutions work, at least until you go all they way down to 1080p

In particular, you cannot use HiDPI on an external display (where the application sees a lower resolution, but the OS renders fonts at full resolution). (No, it does not help to enable HiDPI with Quartz Debug, nor with the QuickRes "Enable HiDPI" button). So the menus and all applications are absolutely tiny.

You could adjust the size of everything on a per-application basis, but then they won't look right when you're working on the laptop display, unless you use something like QuickRes to run the laptop display at its native resolution. I guess I will try that for a few days. So I mainly use my older, power-hungry 2550x1600 30" displays.

If I could just select the highest of the HiDPI resolutions available for the laptop display in the System Preferences, and mirror *exactly* that to this display, I would be a happy camper. You can't do that.

I understand an upcoming release will improve support with HiDPI on external displays. But as it stands, I could not recommend a 4K display for a Mac - or a Mac for a 4K display.

Re:OSX is not ready

[omnichad]

I thought that 10.9.3 addressed this (Not quite two weeks old). Might be time for you to try again.

Re:OSX is not ready

[timeOday]

Before posting that I googled the status and found this page, which specifies "OS X Mavericks v10.9.3 or later" and DOES show the "Larger Text / More Space" (HiDPI) slider being associated with an external display. So I consulted "About This Mac", which says I have OSX 10.9.3. So I re-connected the 4K monitor and tried again before posting, and it still does NOT show me that slider. (I also still don't see it on the 2560x1600 30" display I am using right now). So, I can't explain it. I am skeptical my OSX release has been updated in the last couple weeks, but it says 10.9.3, and the Available Updates only lists updates for iTunes, Safari, iMovie and iPhoto.

Re:A boon for CAD, hopefully

[Austerity Empowers]

pcb layers in Allegro are basically 2 dimensional, you'd need more than just monitor support. Also given a typical stackup for a PCB I'm not sure the "depth", unless exaggerated, would be so helpful. A motherboard is so many inches wide, but a pcb layer is somewhere around what, 8 thousands of an inch thick? Then if the fiber or prepreg is modelled it would appear to be "floating".

A tool from Ansys called SiWave does this (including allowing layers to be exaggerated), I didn't find it to be useful for much more than helping me place probe points. Boards are just too damned flat.

Re:120 hz

[houstonbofh]

Keep waiting. That panel resolution is not popular enough to be continued. 4k will take it over.

Re:A boon for CAD, hopefully

[harrkev]

I often work on fancy PCB designs and can always use more resolution and a bigger screen, within limits. There's no point in having a screen so wide that my head is always moving like at a tennis match.

But more resolution makes editing quicker and easier.

Bah. You PC board wusses. Try doing physical design on a custom ASIC (note my sig).

More pixels definitely helps. I have been using a 30" 2560x1600 (Dell for about $1200), but more pixels for half the money seems like a great deal! The down side is less glass itself, so the pixels are smaller. My old eyes would probably have a hard time staring at text at that resolution. Yes, I know that I can change fonts, but I am a strong believer in more monitors in general. You can have the layout on the big glass, and terminal and/or EMACS windows on the side monitors. Now THAT is a productivity boost. The problem is that with your side monitors having a significantly different pixel density from the main monitor make having an ideal font size impossible. Either too big on the side monitors or too small on the big, central monitor.

Re:A sad truth . . .

[DocSavage64109]

+1 on waiting for consumerization. I'm one of those who bought a scanner when they were about $500, one of the first color inkjets that was also about $500 (Epson stylus color), etc. and that's when $500 was worth something. I'm a little more conservative with this stuff now days.

Re:120 hz

[omnichad]

Not sure about that. If you create a 70" 4k panel substrate, and part of it is defective, you can cut that down into a 2560 panel at a smaller screen size. The bigger the screen, the easier it is to hit 4k, thanks to lower pixel densities. There are only a few pixel densities being manufactured at any given time and they are cut to size for production.

Additional question: why am I seeing advertisements even though the "Ads Disabled" checkbox is ticked?

I have the 39" seiki and love it.

[kenj123]

It does have some issue with contrast and refresh, but its still very impressive. the 28" Samsung could be a better deal now.
Some observations.
1. Youtube has quite a bit of 4k content. however you need a 15-50Mbps connection, mine is a 6Mbps Verizon dsl line so I get quite a bit of buffering. I can download the videos and they are impressive, however, I think you need at least a 60in monitor to appreciate the difference. I've switched my video mode to 1080p and I can see some difference in fine, curved lines, but that's about it. The photos I take with my digital camera look really good on the monitor, but mostly because its so big. If there is text in the picture its easier to read at 4k, but the picture looks almost the same if I set it down to 1080p. The monitor has made me realize I need to upgrade to a DSLR camera.
2. At 2k it is really awesome at displaying text. the 39" is a bit too big, I have to move my head around to see where I'm clicking, but I do program on it and I have ways around that problem.
3. I do watch a lot of nature show on my HD tv. I've been underwhelmed with the video quality of things like tree leaves, fire, flocks of birds flying, ocean waves and water splashing, groups of people or animals running. I'm hoping to see some 4k content of those things and compare to 2k
4. I am watching the pricing on 4k projectors. they are about 5grand right now which is pretty good. not long ago 2k projectors where 3grand. a 4K projector displaying a 120" picture should look incredible. I have a place already picked out to put it in my house.

Re:I have the 39" seiki and love it.

[kenj123]

2 more things that are pretty impressive on 39" seiki at 4k are PDF magazines, especially ones in HQ and Google Earth/Streetview/Maps. All of them have a mix of pictures/graphics and text that look really good at 4k. 3D buildings on Google Earth take a long time to build, partly because my video card is a bit slow.

My eyesight is not likely to improve, and despite the fact it is pretty good for me age, I don't really see any gains to be had from doubling the resolution of my monitors (x3).

I'm the sort of guy who buys the 42" TV because...he knows he can just fucking sit a few feet closer to it if he wants the pixels and screen to appear larger!

The day I need a 4k monitor for programming is the day I need neckstrain from looking up, down and all around.

Re:Sweet, now we just need to wait for OS Support

[EvilSS]

Which if it follows the support for multiple monitors means that windows 14 and Ubuntu 24 should have good support for it. ETA for Mac is unknown.

I have a 4K monitor and Windows 8.1 handles it just fine. The only problem I have is that I have on 4K and one 1080p and Windows seems to have issues getting the dpi correct. 8.1 supports per-monitor DPI but it won't let you set the DPI manually for each monitor, it tries to figure it out and fails. It will either get the 1080p right, and the 4K will make me feel like I need to get my eyes examined, or the 4K looks perfect and the 1080p looks like I already had my eyes examined and was found legally blind.

I have an application for one...

[the eric conspiracy]

I want a 4K 40" OLED display for photo work. This would be something that would come a lot closer to the capability of the sensor in my camera than anything than I can buy now.

In addition the high resolution would be great for displaying large amounts of text, that is for programming.

28" with crappy color gamat and a ridiculous dot pitch isn't close to what I want.

Re:Hi Res

[Overzeetop]

My monitor is so black that I can't see any light at all (Dell IPS). Don't get me wrong, it's not black - at night, with all the lights off, it's clearly not completely black. However, since about 99.999% of my time in front of the computer is with some other form of illumination, or with some portion of the screen being light (and fouling my night vision). I find it hard to get really worked up over "good" blacks that aren't "perfect."

joke is on the consumer

[think_nix]

While 4k is technologically cool the joke again is on the consumer. As in Blu Ray "Mastered in 4k" which isn't realy 4k but "Re-mastered" and downscaled to 2k. IIRÄ they are having difficulties getting true 4k onto disc still? Then apart from the few US streaming services (available in US only TM).

I really don't understand how retailers and manufacturers are still getting away with selling $700-800 laptops with those awful 1366x768 or 720p displays. A few times I was looking for a basic laptop with entry level CPU and memory, and a 14-15 inch screen with nice resolution at an affordable price at Fry's or BestBuy. But the sales people always direct me at loaded models that cost +1000 to get that screen.

Re:But is the end near for 1366x768 laptop garbage

This! In in the market for a new laptop at the moment. I don't have many requirements but 1080p or better is one of them. I your a reallyhigh res external display using an iPad screen for under $100. Why can't I get that option on a laptop? I can get that option on a laptop?

It's a PC monitor, so..

[Blaskowicz]

There's tons of trivial sources of content either dynamically generated, made by others or made by yourself.
Of course, text and PDF, and unix-like terminals. Pictures and photographs ; there's nothing special to do, open a picture that comes out of the camera and look at it.
For games, you can probably play old RTS and such even on low/mid end graphics card. Else this monitor should allow you playing at non native resolutions.

There's even new kinds of content that such a high res display would make possible. Scans of old books, 16th to 19th century with their funny letters, fonts and illustrations, or large format 20th century magazines. You can read them already but most often it looks like garbage and too low res, like fax quality. (OCR fails or require special packages btw when you have funny stuff like the way s and t are linked in "forest", or the s letter that looks like the integration symbol, and then old orthographies and stuff)
High quality scan requires lots of storage, bandwith and display pixels. Now we can have all three on a desktop PC. Reading a 1680s edition of a book written by Newton would be fun, or whatever you can be interested in.

only if we get better OS support for hi res

[Chirs]

Assuming current OS behaviour, I'd be happier with a ~42-46" 4K screen. Just a bit higher pixel density than my current 24" 1920x1200 monitor, but almost 4x the number of pixels.

With current OS behaviour, a 32" 4K screen would have teeny-tiny text in some places.

Re:Lest we forget...

[almitydave]

I'm with you on the term "4K". I can't believe Slashdotters are complicit in this marketing nonsense. There's nothing "4,000" about it. We've been using lines as shorthand for display resolution for quite some time now, and it makes zero sense to switch to columns now, and it isn't even 4K columns.

Resolution: 3840x2160
Pixels: 8.3M

1280x720 is 720p/HD
1920x1080 is 1080p/FHD (Full HD)
2160x1440 is QHD (Quad HD)

Therefore 3840x2160 should be 2160p, QFHD, UHD, or 2K. 4K is utter nonsense. Calling it "Mega 8.3" would even be better.

It's like if Chevrolet said the new Corvette Z06 made over 1200 HP, because they started measuring torque in half-foot-pounds.

Re:Lest we forget...

[almitydave]

Correction, QHD is 2560x1440.

Re:Why?

[Blaskowicz]

It's probably a good display to look at boring numbers and documents.
Text fonts are vector graphics, afterall. So they'll scale and be a bit easier to read.

At $650 that means you can spend $1000 on the whole system (tower or mini-PC plus display). One option is to use an Intel NUC, it comes to mind because it's a cheap and tiny PC with a Displayport ; another is to use an AMD AM1 system in mini-ITX or micro-ATX (same reason, as long as you choose the right motherboard)

Don't care about the updaters. A low end PC like above has a dual or quad thread CPU and 4GB RAM, so you can waste resources on updaters and antivirus (Windows), bad drivers (Linux) and the web browser (both).

I agree that for TV viewing, 4K is overkill, but it makes a big difference on PCs. Until text is sharp and clear without the renderer having to use hacks like hinting and subpixel AA, we still need higher DPI.

Really.

4k displays have been ready for prime time since the middle of last year, when Seiki released their 39 inch 4k tv for around $600. Its just the monitor driving circuitry has been slacking, and HDMI sucks, and they really should have had displayport and 60hz 4k on these panels since the middle of last year.

Quite so
