Uncalibrated – Maximum Backlight Level

If you want a bright monitor, the Omen 27k delivers over 450 nits in SDR mode. That’s more than enough output for any indoor and some outdoor environments, like the video tent at a location shoot. The minimum level is 67 nits, which is a tad bright for dark room play, but I could spend some quality frag time at night. The brightness slider has 100 clicks, so the steps are a bit coarse at 2-4 nits per click.

The black level is average-for-IPS at 0.4534 nit, so contrast comes in just under 1,000:1, also average. The Samsung G8 slays this test because its dynamic contrast feature can’t be turned off. Using the Omen 27k’s dynamic contrast in SDR mode increases the ratio to around 5,000:1.

After Calibration to 200 nits

Calibration doesn’t change the results much. The Omen 27k is still a tad under 1,000:1 and that’s in both Standard and Native modes. You’ll see the same contrast with both color gamuts. ANSI contrast is relatively consistent at 907.6:1 and is a good indicator of HP’s solid quality control.

Test Takeaway: The Omen 27k delivers the same image depth as other rank-and-file IPS panels. The bright and clear image has good color saturation and excellent detail. High maximum brightness makes it suitable for any usage environment, indoors or out.
