Uncalibrated – Maximum Backlight Level
The PG279QM has plenty of output available for HDR content, but in SDR mode, the backlight tops out at a more usable 326 nits. You’ll need a very bright room to warrant turning the brightness all the way up. The brighter monitors let the user use their backlight’s full output range, but this usually means the minimum level is too high for dark room gaming. The PG279QM lets you set 50 nits and goes to a minimum of 42 nits which is much more useful.
The black level is the best of the three IPS screens at 0.3678 nits but pales compared to the VA panels, which are twice as dark. The resulting contrast for the PG279QM is 982:1, which is about average among all IPS monitors. You can use the zone dimming feature to improve this number to around 3,000:1 though it won’t look as good as a typical VA panel.
After Calibration to 200 nits
When the playing field is leveled by calibration, the PG279QM loses a tiny bit of contrast and goes to last place in the test. The visual difference is hard to see with the naked eye and again, you can use the zone dimming option to improve quality to look better than the Razer and Corsair monitors.
ANSI contrast holds solid at 911.3:1 while the Corsair gains a few points. The PG279QM is made from a quality panel part with reasonable uniformity and an effective grid polarizer.

Couple of major flaws for me @ an $840 price point: It's way too small, imo, but I'm prejudiced because once you go to 43" you won't go back...;) The HDR is really lacking...HDR 400 is barely into the DisplayHDR spec, frankly. I had a 32" BenQ with HDR 400, and it's nowhere near as nice as my present DisplayHDR 1000 monitor. Last, it's limited to 1440P--I think that 4k is a must in a monitor in this price range. I think that all too often people get side-tracked by supposed Hz of the monitor and forget about everything else...;) It's hard to beat a wide color gamut combined with DisplyHDR1000 certification, imo. Cut this price in half, and it would be far more interesting.Reply
It could be worth explaining that Rec.2020 had been designed to be wider than what any available display is able to reproduce. It had been designed to cater to future improvements in display technology.Reply
Therefore, there is no actual "Rec.2020 display". like there are displays that support 100% sRGB or DCI P3.
No Hdmi 2.1?Reply
This is such a glowing review, I had to close my eyes before I could turn to page 2Reply
