The EX2710Q supports HDR10 content and includes an HDR emulation feature called HDRi, accessed by a front panel button. It tweaks gamma for SDR content to add depth, but the look is something you’ll have to try for yourself. For these tests, I used an HDR10 signal and the monitor’s DisplayHDR mode.
HDR Brightness and Contrast
BenQ does not include a dynamic contrast option here, so HDR contrast is no better than SDR. In fact, it’s a bit lower than what I recorded for SDR due to an elevated black level. You’ll see that error in the next set of charts. This is a disappointing result given the excellent color performance I observed in both SDR and HDR tests. BenQ could be more competitive in this genre by simply adding dynamic contrast to make HDR stand out more.
Grayscale, EOTF and Color
I ran gamut tests using both DCI-P3 and Rec.2020 and found good accuracy there. The EX2710Q is over-saturated a bit in the mid-tones like most wide gamut displays. This provides a little extra punch to the image. The same is true for content mastered to Rec.2020. The points are close to their targets until the monitor runs out of color at around 85%. Hue values run true, which is a good thing. Though contrast is low, the EX2710Q’s HDR is colorful with a natural look
The HDR grayscale run shows some blue errors in the darkest steps. Luminance values from 0-15% are too high, which also lowers contrast and makes shadow areas more gray than black. Above 15%, the luminance curve is on-spec with a tone-map transition point at around 65%. Though HDR content is accurately rendered, it has no more impact than SDR. The color and accuracy are there but not the extra dynamic range.
