Uncalibrated – Maximum Backlight Level
The Omen 27u is a very bright monitor with more than enough output for any situation and environment. You'll never pine for light output with an SDR peak of over 409 nits. The minimum level is 69 nits which is a tad higher than my preference for dark room gaming. I’d rather use 50 nits for that. With such a broad range available, each click of the 100 brightness steps is around 3 nits.
The 27u finishes third in the black level comparison and has the fourth-best contrast of the group. At 1,088.8:1, it’s about average for IPS panels. Some of the latest displays can top 1,200:1, and that’s a visible difference. But the HP still delivers good image depth and texture.
After Calibration to 200 nits
Calibration moves the Omen 27u up to second place in the contrast contest. My only adjustment was to brightness; RGB sliders were left alone. The Philips retains its top spot, but the HP isn’t too far behind. It also scores well in the ANSI test with an excellent 1,047.9:1 ratio. There is no doubt that the 27u is made from quality components.
