The key info missing is that this is the AU Optronics HDR capable panel that finally makes 4K almost make sense. I still haven't seen what the frame rate is under ULMB or even if Asus is supporting it. This frame rate should allow 120 Hz at least under ULMB if it is supported.
In TPUs latest Game test Suite at 4k with a premium 1080 Ti, of the 222 games in the suite, at 4k ...
18.2 % can't break 50 fps
36.4 % can't break 60 fps
50.0 % can't break 70 fps
86.4 % can't break 80 fps
And only one (GTAV) breaks 90 fps and then by only the slimmest of margins (90.9). So for those kinda numbers ... 4k is a bit hard to justify, especially considering ULMB only starts to make sense at about 70 fps and half the games can't do that.
I was expecting DP 1.4 but some sites reporting 1.3. Can't wait to see it face off against the Acer model (Predator X27) with the same panel. Still, not gonna get too anxious until a video card exists that can keep up with it. Right now, probably looking at $2,700 - $3,000 just for the SLI'd GFX cards and the monitor.
My take ... wait until price drops in about a year. Nvidia card performance generation to generation from 7xx to 9xx was 45% at 4k and the overclocking headroom on the 980 Ti was over 32% on top of that. The 1080 Ti is almost twice as fast (85%) as the 980 Ti ... tho Boost 3 has put a big nerf on the overclocking at just about 12%. Or perhaps nVidia is following AMDs path and more aggressively clocking the cards in the box.
However, the article could as well been entitled "Asus Announces ... Version 3" as Asus and AU Optonics first demonstrated the panel at Computex in 2016 and again in January at CES.2016
