Is LG's New Ultra Widescreen Display Better Than "Normal" 4K?
Iddo Genuth (903542) writes "Forget about 4K displays, are Ultra Widescreen 'cinematic' displays the real deal? Earlier this year LG announced its new 34UM95 – a 34-inch Ultra Widescreen monitor with a cinematic 21:9 aspect ratio and a generous 3440 x1440 resolution — a recent hands-on review suggests that this monitor might be the new productivity king, for those who simply can't stand that annoying bezel between their multiple monitors. Linus Sebastian had a chance to play with the new LG 34UM95, and although he seems to start as a skeptic (after all, how really useful can a 21:9 display be right?) he ended up his review fully converted, with no going back. We still think that pro graphic users will not rush to switch over their EIZOs and NECs for this baby, but video editors, gamers, programmers and basically anybody who loves multitasking, might be very tempted — what do you think?"
I would submit that you think 1920x1200 is "plenty for work and pleasure" because you simply have no experience with "better".
I use a trio of Dell 30" monitors at 2560x1600, I can most assure you that it makes a difference. I've had to, from time to time, use another computer with a pair of older Dell 27" monitors at 1920x1200 and it is horrible to go back.
The idea that 4k is "faddish? Really? Why don't we all go back to 19" monitors at 1280x1024 while we're at it?
You simply don't know what you're missing.
At recommended viewing distances, 4K resolution is difficult for most of the population to detect a difference in.
Um... just no... that is completely and totally false, I wish people would stop repeating that nonsense... Maybe YOUR eyes suck and you can't see a difference, but put them side-by-side, sitting 6 to 10 feet away, the difference is clear and obvious to most people...
I speak from experience...
The problem with 4k monitors is that they have slow refresh rates (30hz?), slow response time, and all the usual non-IPS problems like poor viewing angle and color. None of which matters terribly for programming (save response time which might make scrolling a bit blurry.)
More wrong information. 60hz 4k panels are out now, and they don't have poor viewing angle or color. You simply need DisplayPort to get 60hz (which anyone buying such a monitor today should have).

60hz, IPS viewing angels, just crazy expensive at $3,500 (actually below $3K now, give it a few years to get cheap).
You should go to CES sometime
I don't need to go to CES. I bought that monitor three weeks ago when Fry's had it for a little under $1k. It is huge, I did not really like it. Much of the monitor is in my peripheral view, and moving the mouse from far-left to far-right is a pain. I decided to use my "old" 1920x1200 again and use my 34UM95 for my flight simulator.
The idea of having a gazillion xterm's next to each other is great, but it didn't work for me.
I'm not a complete idiot... Some parts are missing.
Actually, it is - if you sit 8-10 foot away from your screen you need a 60" TV to see a resolution higher than 1080p.
4k is pretty much useful for monitors only (where it's useful because you sit 2 feet away from them).
How about we just use decimals so we can understand this more easily?
5:4 = 1.25:1
Made common with 1280×1024 displays
4:3 = 1.33:1
Old computer monitor standard
16:10 = 1.6:1
Made common with 1280×800, 1680×1050 and 1920x1200 displays
16:9 = 1.78:1
(HD video standard)
Became most common aspect ratio for computer displays in 2012
A4 paper size = 1.41:1
Movies usually are in 2.39:1, 16:9 or 1.85:1
256:135 = 1.9:1
Since 2011, several monitors complying with the Digital Cinema Initiatives 4K standard have been produced. The standard specifies a resolution of 4096×2160 and an aspect ratio of almost 1.9:1.
I don't read your sig. Why are you reading mine?
Because it's approximately true. Nominal resolution of the human eye is 1 arc-minute (1/60 of a degree), therefore a 1920 pixel wide display will subtend 32 degrees horizontally at the resolution limit. At 9 feet (108 inches), a 62 inch wide screen will subtend 32 degrees horizontally. Since screen sizes are measured on the diagonal, that equates to a 71 inch diagonal.
Human eyes are variable in resolving power, both because of their optics, density of the cones in the fovea, and brightness of the image source. Our retinas and brains also do image processing, so we can detect narrow lines, like a power line against the sky, at better resolution by interpolating eye movements (which change which cones are getting the image) and contrast enhancement.
An image with lots of narrow high contrast linear features (like text) can benefit from somewhat better pixel density, but for general colored images it does not help much.
20/20 is the ability to read things made of lines 1 arc-minute thick. If the letters are smaller, you might not be able to read them, but you can tell tell it's text because the rods and cones are much more dense than that. "General colored images" usually have texture.
Another big value that's not discussed often is that the higher the resolution, the harder the pixels are to see. This is why even 480i content looks better on an HD TV -- it's a much smoother, cleaner picture. Also, through some quirk of physics, when my eyes de-focus I can see pixels.
Not that this wasn't entirely predictable.
