Uncalibrated – Minimum Backlight Level

The backlight goes very low on the XB280HK, covering a range of 239cd/m2. A reading of 31.0382cd/m2 is pretty dim. If you click back to the previous page, though, you’ll see our brightness settings for 80 and 120cd/m2, which are much more useful in dark rooms.

Of course, that results in class-leading black levels. Too bad Acer’s contrast is not high enough to take advantage of this.

Contrast prior to calibration lands at the bottom of the group, regardless of backlight level. Still, there is improvement ahead. Check out our calibrated and ANSI results below.

    On first glance I thought I wouldn't have to see "we will be reviewing XB270HU soon" quote again. But then I realized it's XB280HK. Oh well, guess have to endure that quote for few more time :rolleyes:

    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

    Should be at least version 1.2 for 4k @ 60Hz since this version has been doing this since year 2009. v1.2a is the same Res/Hz deal but brings added support for Freesync.

    Why do they keep pushing 4K for gaming. True gamers have always regarded fps as king and 4K is one-quarter the frame rate of 1080. Gamers don't need expensive 4K monitors driven by expensive cards at ever-lower frame rates (via G-sync). This is chasing the proverbial tail and counterproductive. Regular 1080p, v-synced at a constant 144 fps would be better than all that stuff.

    For peeps that want gaming at 4k now, this is the best option I've seen so far.

    4K is cool but GPUs cant handle it well enough yet. I'd rather have 1080p at high fps and gain an extra 1-2 frames of lag, but to each their own.

    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.
