hoodafukisaliceNo, there is no high refresh 4k monitors at all yet. Not until Acer and Asus release their 27 inch 4k @ 144Hz monitors later this year or earlier this year.
Suckfest9001Asus lied to you then; It's the cables that limit the refresh rate. Displayport can do 4K full color range at 60Hz, and that's the best you're gonna get for now. Even then, with the 1080 and 1080ti you have to lower your graphics settings just to hit 60fps on most modern games, let alone exceed it. I'm still waiting for a graphics card that allows me to play games at highest settings at 4K 60fps. Hopefully the Volta cards coming out next year will do it.
Apple2456Well, I guess it's been a while since I got my 4K monitor; 1.3 was the standard then.
Even if DisplayPort supports it, the 1080 and ti's benchmarks have shown that they couldn't even do modern games at highest settings, 4K resolution, and 60fps. If you wanted to push it past that, You would have to severely lower the graphics settings or buy several cards and SLI them together (which brings on problems of its own). If 120Hz is your thing and 60Hz just isn't enough, consider a 1440p monitor. Right now, you literally can't have everything. Best bet is to wait for the Volta cards to see what they can do.
White.RabbitFor many games one can hit pretty solid frame rates (Diablo III, StarCraft II, LOL,...). It is only the latest AAA titles that have trouble. Personally, I prefer 1440p right now. Perhaps at 42" it matters, but at 27" I cannot even tell the difference. Also, you should be turning off many setting (such as anti-aliasing) when gaming at 4k. You are not going to be seeing any jaggies at that resolution. Again, I could be wrong for such a large monitor though.
SkipPpAt this size, AA is nice. And yeah, of course those games look ok. They were made by Blizzard to be optimized for mid-low end systems, as with all Blizzard games. If you're looking for stellar graphics, you're looking in the wrong place with Blizzard. Don't get me wrong; they are extremely fun, but they don't push any boundaries. My assumption of the type of person that cares about 4K or 120Hz, also cares about top-notch graphics. But hey, to each their own.
