The extra contrast available in the EX2710R over the EX2710Q makes it a far better HDR screen. Though the difference between HDR and SDR isn’t huge, it still qualifies as better than average.
HDR Brightness and Contrast
The EX2710R easily tops its DisplayHDR 400 certification with just over 421 nits. That’s plenty bright and it creates highlights that pop. With a low black level, it delivers decent contrast at around 2009.9:1. I was disappointed to see that score come in lower than the SDR ratio. That puts it on par with other VA monitors that don’t have dynamic contrast features. It is at least better than the other IPS screens here save the Razer, which does have dynamic contrast. If you’re choosing between the EX2710R and EX2710Q, pick the R for its better HDR image.
Grayscale, EOTF and Color
In the grayscale test, the EX2710R shows some slightly visible blue errors in the darkest steps. This contributes to its black level, which could be lower. You can also see in the EOTF chart a slight rise in the white line at zero and 5%. This is a luminance tracking error that reduces dynamic range. BenQ could address this with a firmware update, and it would likely raise the HDR contrast ratio to at least 3,000:1. The good part is that tracking from there is nearly perfect. The transition to tone mapping happens smoothly at around 65%, also ideal for a 400-nit monitor.
In the HDR gamut tests, I compared DCI-P3 and Rec.2020. DCI is a bit over-saturated, which isn’t a bad thing. HDR color is definitely more saturated than SDR. The EX2710R nearly fills the gamut but comes up a tad short in green, like most wide-gamut screens. In the Rec.2020 run, it tries to up red and green hues to fill in the missing color. The net effect is positive, with rich hues in all the HDR content I viewed.
