The default Standard mode is pretty close to the mark, and most users will be satisfied with its performance. For those who wish to calibrate, the User mode can be adjusted to a higher level of accuracy. After tweaking the RGB sliders, we achieved an average error of less than one Delta E. Gamma rides a tad dark, but the presets are too far apart to fix that issue. We also encountered a few color saturation and luminance errors. It's a bummer that there is no CMS to help. Overall, however, the XB280HK is just as accurate as other gaming monitors in its price range.
Please try our settings below. For those interested in brightness levels below 200cd/m2, we’ve included the settings for 120 and 80cd/m2.

Contrast ratio, brightness, chromacity & gamma tracing is where XB280HK looses the ground, but to be fair, most of the gamers won't be noticing much difference at all. But it is kind of disappointing to see Planar do better in these fields than Acer utilizing the same panel. I don't know, maybe the overdrive somehow worsen the results?
But ofcourse, it does well on uniformity and response time. Makes me wonder why XB280HK doesn't have ULMB if it's supposed to be a bundled feature with G-Sync. That should've helped in 60Hz panels more, rather than 144Hz ones.
But anyway, XB280HK looks promising, although I don't think 4K is what I prefer for gaming+life (although I do for gaming only).
It's 1.2a I presume. Since that's what is capable of 4K@60Hz other than HDMI 2.0
People that like to play games also like to play games in ultra HD resolutions.
ULMB uses flickering to lower persistence, which reduces the motion blur. If you've ever used 60hz CRT monitors, you'll know that flickering is painful on the eyes. This is why ULMB mode is not offered on 60hz monitors, and likely won't be offered on anything less than 75-85hz.
Top end GPU's can handle 4K just fine. You just don't play it at max settings. What is better, medium to high settings and 4K, or maxed at 1080p? That is a subjective question, and will vary from person to person.
That said, I prefer higher refresh rates than 60hz, so I'll be going 1440p before 4K.
