The GS32QC handles HDR10 signals with an automatic switch to HDR mode. There are no image controls or additional presets, but I found decent performance when compared to other budget HDR screens.
HDR Brightness and Contrast
You don’t get any extra brightness from the GS32QC in HDR mode. I tried measuring full screen and window patterns and got the same results. There is no dynamic contrast feature in play, so HDR brightness, black levels and contrast are about the same as SDR. As a VA panel, it will deliver better HDR quality than similarly equipped IPS monitors like the G272QPF and VI-01. If you want a more impactful HDR experience, you’ll need to spend more for a display that has field or local dimming capability.
Grayscale, EOTF and Color
The GS32QC’s HDR grayscale, EOTF and color display a similar level of accuracy to what I found in the SDR tests. Grayscale tracking is free of significant errors. The brighter steps above 60% are ever so slightly cool in tone. Luminance tracking is excellent, with near-perfect adherence to the reference curve and a transition to tone-mapping at 65%. This is correct for the measured white level.
HDR color tracking is similar to what I measured in the SDR tests. Green and blue are under-saturated, with a movement towards cyan in the blue primary. Low and mid saturation targets are closer to the mark. A lot of content focuses on these areas of the gamut triangle. Both DCI-P3 and Rec.2020 reference content shows the same behavior. In the realm of budget HDR monitors, this is typical performance.
Test Takeaway: The GS32QC focuses on game performance and delivers excellent results in that area. Though it seamlessly supports HDR, it doesn’t render an image that’s significantly different from SDR. Since it’s VA, you get excellent contrast in all content. And its HDR accuracy means you won’t see anything out of the ordinary when playing HDR games. For $250, I have no complaints. Its HDR image quality is comparable to other budget gaming screens.
