The P2510S supports HDR10 signals with an automatic switch as long as you set the HDR option Auto. There are three total HDR picture modes that differ in their tone-mapping and luminance tracking. There is no dynamic dimming available to increase contrast.
HDR Brightness and Contrast
The P2510S manages a tad more brightness in HDR mode with a peak just shy of 378 nits. Black levels are about the same as I saw in SDR mode so contrast is a little higher at 1,323.9:1. You can see the benefit of dynamic dimming in the top two screens which increase their HDR contrast four- and nine-fold. The P2510S has good native performance but is unable to achieve higher potential.
Grayscale, EOTF and Color
The P2510S shows slight green errors in the brighter steps of the HDR grayscale test. They are visible to the naked eye and cannot be adjusted away. I measured all three HDR modes and found Auto provided the best luminance tracking. Game and Movie were darker in tone with some clipped shadow detail.
The P2510S’s wide color gamut is used to best advantage with full coverage of DCI-P3 and a bit of general over-saturation to provide more vivid hues. This effectively provides a little more impact than SDR. I noted slight hue errors in magenta and yellow due to the grayscale issues. The P2510S tracks Rec.2020 color points with a similar level of over-saturation until color runs out at 85% red, 75% green, and 90% blue. This is typical of all wide gamut monitors I’ve reviewed. Only a very few can cover more of Rec.2020.
Test Takeaway: The P2510S delivers adequate HDR performance which could be made better with the addition of dynamic dimming. In fairness, almost no monitors in this price range have that feature. Tone mapping is accurate, but there is a slight green tint due to grayscale errors that can’t be corrected. There is plenty of nicely saturated color with full coverage of DCI-P3. HDR content is very colorful and bright.
