The Omen 27qs G2 comes out of the box set to its Standard picture mode, which unusually uses the sRGB color gamut for SDR. This is the correct choice by broadcast standards, but most wide gamut monitors render their full native gamut for SDR to make themselves more colorful in a store display. I suspect most users would rather have more color, so I’ll show you how to achieve that here.
Grayscale and Gamma Tracking
Starting with grayscale and gamma, you can see that the Omen 27qs G2 doesn’t need to be calibrated. Only the 80-100% brightness steps go above 3dE, and only barely. No one, including me, will complain about this. Gamma is spot-on with ruler straight tracking. This is excellent out-of-the-box performance.
To get the full color gamut, I switched to Native mode where grayscale was once again without visible error. 70-90% brightness starts to push blue, but I couldn’t see this in actual content, only in a gray step pattern. Gamma is almost perfect but shows slight dips (too light) at 10 and 90%.
With a few tweaks of the blue slider in the RGB Gain Adjust menu, I achieved perfect grayscale with all errors except the 100% step below 1dE. Gamma is unchanged. This is reference-level right here.
Comparisons
The Omen 27qs G2 compares well to the other screen with second-place finishes in every test. Calibration is not necessary in either Standard or Native modes. And if you make the adjustments, the reward is pro-level color. With such tight gamma, you won’t see any unnatural luminance issues at any point in the brightness scale. It doesn’t get much better than this.
Color Gamut Accuracy
Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.
In the Omen 27qs G2’s default Standard mode, you can see that sRGB is the design goal with a tiny 1.09dE average error. Every point is on target with no visible issues present. Switching to Native mode delivers much the same accuracy, just over a wider gamut. Only green is a touch undersaturated which is very good for a non-Quantum Dot display like this. You can see slight hue errors in magenta and cyan which are fixed after calibration. The average error drops below 1dE which is something few monitors achieve. This is reference-level performance.
Comparisons
There are no issues in the color test with any of the screens in the group and the Omen 27qs G2 sits atop the chart with a 0.99dE score. I’ve only measured a few monitors with better color accuracy than this.
In the volume test, it’s easy to see which screens have Quantum Dot layers. The AOCs top 100% coverage of DCI-P3. But the Omen 27qs G2 is in the thick of it with an excellent 93.54% score. The IPS average is around 90% so this is a win. And it’s an improvement over the Omen 27qs from two years past, which covered 89.72%. The G2 has a bit more green, which can easily be seen in content when compared. The nearly 100% coverage of sRGB is ideal. The Omen 27qs G2 is qualified for color-critical tasks.
Test Takeaway: The Omen 27qs G2 renders accurate and vivid color right out of the box and gets even better with a simple calibration. It’s an improvement over its predecessor for sure and is on par with the best IPS screens I’ve tested. You can easily switch between sRGB and DCI-P3 by using the Standard and Native modes.
