VESA Embedded DisplayPort 1.4a Paves Way For 8K Displays, Longer Battery Life
MojoKid writes: The VESA standards organization has published the eDP v1.4a specification (Embedded DisplayPort) that has some important new features for device manufacturers as they bump up mobile device displays into the 4K category and start looking towards even higher resolutions. eDP v1.4a will be able to support 8K displays, thanks to a segmented panel architecture known as Multi-SST Operation (MSO). A display with this architecture is broken into two or four segments, each of which supports HBR3 link rates of 8.1 Gbps. The updated eDP spec also includes VESA's Display Stream Compression (DSC) standard v1.1, which can improve battery life in mobile devices. In another effort to conserve battery power, VESA has tweaked its Panel Self Refresh (PSR) feature, which saves power by letting GPUs update portions of a display instead of the entire screen.
It seems like the bigger sticker with 4k is how most interconnects have been locked to 30hz. eDP 1.4a supports 8k but at what refesh rate ?
Isn't that beyond human perception?

We'll all still have 1366x768 laptops anyway. Resolution in the real world is stagnant.
Of 8k for the most part? I mean, ok if it's for VR I get it. But for a TV you'd have to have something the size of an Imax screen to appreciate that resolution in any way whatsoever. Heck even for 4k you need a 100"+ screen to actually care at all.
Dear TV makers: Where is our REC 2020 color gamut screens? Or screens with a brightness of 5k nits or more? Or our 10,000 to 1 contrast ratios. You know, things our eyes can readily see a difference in an appreciate beyond "moar pixels!!!" I'd buy a glassesless 3D display if it was a lightfield display and refracted light correctly for different focusing depths, that would be really cool. But I do not need an 8k TV.
Wait for 3D holographic displays and projectors coming *real soon now*.

I seem to need wider than 1024 pixel window to prevent overlapping columns on Slashdot's main page now.
People have been focusing on 8K monitor actually (7680 x 4320 at 60hz) as if this cable is hard wired to only support a specific config. It supports multiple MST configurations, which means the ability to configure panels into one screen - using multi streams, or multiple monitors with multiple streams. This means it has more than enough support to drive 3 x 4K monitors using this cable, which I personally could easily put to work (I have 4 monitors of various HD resolutions and sizes). I would like having 3 x 40 inch 4K monitors on my desktop. It would be great if I could use a laptop and have the same setup (though there is a limitation on that due to processor restrictions right now - though Skylake looks like it will have enough power to do it). Now if they were able to do a cockpit type monitor that curves around as one monitor with 23040 x 4320 @ 60 hz that would be great to (but hard to move around :o ).
I have seen some people complaining that 7680 x 4320 is not 8K (8000 x 4000) but if it has the bandwidth for the first, it has the bandwidth for the second configuration (less pixels). They seem to fail that the cable is not for a specific resolution but to support higher bandwidth monitors going forward.
What happens with thunderbolt? Will there be data only thunderbolt? Will apple have to have Display only ports on the next mac pro?
4K and 8K are not as much of a benefit to TV as it is to monitors. When pictures are in motion, the higher your perception of image detail is not as noticeable by ones eyes. As a monitor for a work environment where images are not motion pictures, 4K and 8K are very easily noticeable. It will give the image more depth and you will be able to use the extra workspace on a 40+ monitor. If you shrink down the image it is more recognizable than if you display the same image in the same size on a HD monitor. You have both peripheral vision for dashboard use, and a neck to move back and forth to different documents/ images / text displayed on a larger workspace -- but when you are looking at something you are focusing on a small area on the monitor. If the extra resolution were not usable to provide extra depth to your pictures, cameras would not be pushing up to 50Mpixel resolution.
People confuse the difference between perceptible and optimal. So ya, to see every pixel on a 4k screen, it needs to be pretty big (or you need to be pretty close). However we should stop wanting that. Computer monitor have too long taught us that we should work at a resolution where we can make out each and ever pixel. Rather, the individual pixels should be so small that they are completely imperceptible under any circumstances. That requires a lot more pixels.
As for your other requests, have you done any research on what is available, and the difficulties of what you are asking? This is the real world here, there are real engineering challenges. Let's go one by one:
Rec 2020: That requires laser illuminates. Since the primaries are points along the spectral curve, you have to have monochormatic light sources, meaning lasers. You can get that from laser projectors currently, if you are willing to pay, no consumer displays. Of course it matters little since there is no Rec 2020 content. However you can have a DCI display no problem, the Panasonic 4k displays are just shy of a DCI gamut. Oh and Rec 2020 specifies an 8k resolution, by the way.
5k Brightness: You don't have a power plug in your house sufficient for that kind of brightness, nor would you want to crank a display that high. Go have a look a commercial displays sometime, go see one of these things turned up to 700-800 nits. They are painfully bright in anything but a very brightly lit space. We are talking stuff made for direct sunlight usage. You don't want that in your home. That aside, you'd need a massive amount of power to deal with something like that, and noisy cooling fans to go with it.
10000:1 contrast ratios: You can have that right now. High end LCDs pull it off with backlight dimming, OLEDs can handle it as is. You want an LCD that does it static? Not going to happen, and a basic understanding of how blocking technology works will tell you why. Emissive screens like OLED can do it without much trouble, but of course you are going to have real issues if you want a high bright display out of those since brightness is a killer for emissive technologies.
Seriously, less with the silly whining. If you truly are interested in display technology, go learn about it and the limitations and issues. But don't just bitch and act like people should be able to magically figure out a way around tough engineering challenges. If it was easy, it'd be done already. If you think you have a solution well then, get on that. Go solve it and make a bunch of money.
I haven't heard about the Video Electronics Standards Association since I bought a video card with the ISA bus for my Windows 3.1 computer. I remember installing the VESA driver from a floppy disk. 256 bit color at 640 x 480. I'm showing my age. lol
Because it's easier to maintain quality when post-processing if your shoots and edits take place in a higher resolution, and you downsample to get the final product. 8k edited to 4k is going to look better than 4k to 4k. Same as why movies are shot in 5k or higher when BluRay is "only" 2k.
Latest iMac sure looks nice, but I wonder if 4K at close distance would be any different. After all, it's only considered useful for pretty big TVs. Sounds like number-based marketing like clock speed in Pentium 4 days. What would the framerate be like if I try to play a game on this thing?
I did not hear much discussion about how HD on a 13/15 inch laptop was overkill when it became standard more than a decade ago.
I use a 40 HD monitor as my main display, but I would definitely notice the difference the difference in having a 4K monitor (when I run the iPhone simulator - the resolution is high enough that it will not fit on the screen). A 40 inch screen is 600+% larger than that 15 inch laptop. So to keep the real resolution (pixel size) the same for a 40" monitor you would require 5K.
In addition I use multiple monitors (4), and displayport monitors have the ability to be chained on the same connection -- which would allow me to get a laptop (later this year when Skylake is out) and have 3 x 40" monitors attached using this standard.
Why dont they just support multiple cables to one monitor for the higher bitrates?
Just waiting for a decent 1.3 4k monitor and graphics cards to actually ship.
My dual screen 4k CTX CRT monitors are starting to look like teh suck! what took so long? I'm jones'n for 16K after just writing that setence. Hurry up with the pixels!
And, yeah, some content that takes advantage of said pixels.
And some faster internet speeds to get some of that pixelly goodness.
And some better cable/satellite TV providers that will provide said content.
Madness
It is madness to increase of the data rate in video signals even further. A monitor cable transmitting 32.4 gbps is not a good solution. It is something engineers can boast about but it also limits cable lengths and makes them more expensive. Trying to get 4K UHD over 20m is as expensive as a PC and the display together.
Instead they should adapt and norm low-latency compression methods for the transmission of video signals. 1 gbps should be more than enough to transport an 8K UHD signal with 100Hz (and without any gamer noticing a difference).
The inclusion of DSC is a good start but is seems to be just a sidekick.ï
I personally see little value in 8k displays under the size of an /entire wall/ of your house.
That being said, in 10 years, who knows, maybe we'll lay a flat, OLED sheet on a black painted wall and.... you know 240" TV?
As for the frame rate, for the /most part/ I see little value in high refresh displays, but there are uses. If this plus is 'open' (no license fee) and powerful, well so be it. The more performance the better.
That being said I did just discover this recenttly

Sigh.... standards? Can we just have fucking one, open, real goddamn powerful one and be done with it?
The f'n 12yr old CRT sitting in my closet has a higher refresh/response/resolution than the 27" lcd on my desktop. :(
