The XG32UCWMG delivers solid accuracy in its Racing picture mode with no need for calibration. You can tweak using color temp and gamma presets plus six-axis color saturation controls. Also available is an accurate sRGB mode.
Grayscale and Gamma Tracking
The XG32UCWMG’s grayscale errors are mostly invisible with all values save the 100% step below 3dE. You won’t see this in actual content. Gamma tracks very close to the 2.2 reference with just slight deviations at 10, 20 and 70%. Again, these are invisible errors.
Calibration brings grayscale tracking even closer to perfection, but a slight gamma anomaly is introduced. It’s a dip from 70-90% brightness that manifests as slightly elevated highlight areas. This is barely visible and since color is improved, it’s a worthwhile tradeoff.
If you want sRGB, the best option is to choose it from the Color Space options rather than using the sRGB picture mode from GameVisual. Both are accurate, but the former retains calibration controls. They aren’t needed, though; the above chart represents sRGB with no additional adjustments.
Comparisons
The XG32UCWMG continues the tradition of color-accurate OLEDs with an excellent score of 2.17dE in the default grayscale test. Though it finishes fifth here, none of the six monitors needs calibration, so visually, they are equal. After a one-click change to the red slider, the score improves to 0.60dE, good enough for third place.
Gamma is close to perfect with a 0.13 range of values and a 1.36% deviation from 2.2. The actual value is 2.17. But a couple of the others are closer to perfect. This is not a difference you’ll be able to see in practice. I have no complaints here.
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.
The XG32UCWMG hits its marks in the color gamut test with equal precision. You can see a tiny bit of oversaturation in red and a hue error in magenta, but these are invisible issues. A 1.62dE score means all aberrations are invisible to the naked eye. After calibration, the XG32UCWMG drops below 1dE with a 0.95dE score. That puts it among the most color-accurate monitors I’ve tested across all categories.
The sRGB option in the Color Space menu yields excellent results too, with an average error of just 1.31dE. It doesn’t get much better than that. Though you can calibrate this mode if you wish, it clearly isn’t necessary.
Comparisons
The XG32UCWMG cracks the 1dE barrier in my color gamut test but it isn’t the only one here capable of that feat. The top four screens all render professional-level accuracy, which is impressive for any category of display. That the worst of them is at just 2.03dE speaks well of the OLED genre.
The XG32UCWMG manages just a hair less than 100% coverage of DCI-P3, putting it in third place behind the top two Quantum Dot screens from HP and Acer. 7% can be seen, but the difference is small. The XG32UCWMG is plenty colorful, and for those seeking precision, 100% coverage is ideal.
Test Takeaway: The XG32UCWMG delivers superb color, grayscale and gamma accuracy. Calibration is not required, but it is available should you wish it. Also available is an equally accurate sRGB mode, which will be useful to photographers and graphics pros. The only missing element is Quantum Dot color, but the XG32UCWMG manages to cover almost 100% of DCI-P3, which is no small feat.
