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.

    Mfg's should not be allowed to label something "HDR" with an edge lit panel and no local dimming.
    It's fake "HDR" at best.

    700$ is one garbage price to pay to get 144hz at 4k

    there's no way 144hz cost them more vs a 60hz model to make; it's pure price gauging

    It's been 7+ years and we're still at 700$+ for high refresh 4k; I just don't buy it:rolleyes:

    32 ms input lag?? You sure?? I just bought it but I'm going to return the bloody thing. That is way too slow. Who wants 32 ms input lag! What monitor has 32 ms input lag these days? Ouch!! Or did you meant 3.2 ms. Cause 3.2 or 32 is a huge difference!
    If this is a mistake I would change it in the article cause no one will buy this monitor. I almost got a heart attack reading this! Going to return it.. This is bad if 32 ms input lag is the real thing..
