The 32UHD144 is a very capable HDR monitor with a zone dimming edge backlight. It has 16 dimming zones, which enhance contrast significantly. An HDR10 signal switches modes automatically. 

HDR Brightness and Contrast

The 32UHD144 is rated for 600 nits in HDR mode, and my sample beat that handily with nearly 700 nits of total output measured using a full-field white pattern. That’s seriously bright. In practice, you’ll only see this level in small highlight areas. Thanks to the effective zone dimming feature, black levels are relatively low, and contrast is above average at 10,875.2:1. The Mini LED ViewSonic achieves high values thanks to its incredibly bright backlight and super low black levels. But that level of performance will cost you about double the price of the Corsair and the other screens.

Grayscale, EOTF and Color

I was surprised to see a lack of image control in HDR mode. There is only a single picture mode and no means of changing color. But obviously, that isn’t a problem given the results shown above. The 32UHD144 is one of the most color-accurate HDR monitors I’ve tested. Grayscale tracking is visually perfect. The only flaw is some lightness at the lowest level. This is likely due to the speed in which the zone dimming backlight reacts to changes in picture levels. In practice, the HDR image is very deep with true blacks and very bright highlights.

In the color test, the 32UHD144 is clearly using the Rec.2020 reference for all content, even when mastered to DCI-P3. You can see in the DCI chart how green tracks toward the Rec.2020 points, which means it’s a tad bluer. This will be hard to spot in actual content, but a firmware update might be in order to ensure that color tracks correctly for the content’s reference gamut. Saturation points are linear in progression with slight over-saturation overall, not a bad thing.
