We put the Omen 34c through a series of benchmark tests using our standard gear: Portrait Displays’ Calman calibration software and a Klein K-10A colorimeter. We also subjected it to a gauntlet of games to measure input lag and assess its real-world performance.

In our first test, we benchmarked brightness using the Omen 34c G2’s default gaming profile with an SDR signal. In that setting, we measured a maximum brightness of 329 nits, slightly lower than the rated 400 nits maximum. Peak HDR brightness resolved similarly, increasing to 353 nits at a 2% window size. We tested the monitor under default, out-of-the-box settings, as we do with all monitors we test, so there’s potentially room to achieve a higher brightness through additional calibration or experimenting under another preset.
Moving on to contrast: The monitor has a rated contrast ratio of 4,000:1. (Contrast ratio indicates the difference in luminance between the brightest white and the darkest black.) While its contrast ratio is nowhere near as high as the near-infinite contrast ratios of OLEDs (because OLEDs can display true black), the Omen 34c G2 still delivers a decent viewing experience, especially when playing games.

On our color gamut tests, we found that the Omen 34c G2 spans 84.4% of the Adobe RGB color gamut, 96.8% of the sRGB gamut (see the chart above), and 79% of the DCI-P3 gamut (see the chart below). That’s fine for casual gaming, movie watching, and general internet browsing, but don’t expect to rely on this panel for pro work that demands pinpoint color accuracy. For that, consider a large-screen monitor specifically designed for content creation, such as the BenQ PD3225U.

During testing, we observed a slightly washed-out picture with the brightness set to maximum. The color range is nowhere near as excellent as, say, that of the Odyssey OLED G9. But that’s to be expected given where the pricing lands.
