Uncalibrated – Maximum Backlight Level
The EX2710R addresses the biggest concern I’ve had with BenQ’s Mobiuz monitors, contrast. Its VA panel excels above not only IPS, but many other VA monitors too. Peak brightness is around 268 nits which is enough for any indoor environment. A little more headroom would be welcome but that is a minor point.
The black level is far darker than any IPS monitor can deliver, and that shows clearly in actual content, and in the comparison chart. With over 3,200:1, the EX2710R has more than triple the dynamic range of nearly all IPS displays.
After Calibration to 200 nits
Calibration in the EX2710R’s case was just a matter of setting the backlight to 200 nits. No other adjustments were made, and I used the RPG picture mode. The black level is still two-and-a-half times lower than the best IPS monitor here from Monoprice. 3,263.4:1 is one of the highest native SDR contrast ratios I’ve recorded.
ANSI contrast is only a tad lower at 2,632.9:1. It truly doesn’t get much better than this without enhancements like full-array zone dimming or some sort of dynamic contrast option. The EX2710R delivers a deep, colorful image with rich saturation and realism.

That does not make sense. You clearly have other VA panels without those features that are hitting much higher than that like the Dell 3220 or 3222dgm.
HDR contrast is lower than SDRSo the Dynamic Range in High Dynamic Range mode is smaller than the Dynamic Range in Standard Dynamic Range mode. A further illustration that "HDR400" can be read as "this display is not HDR in any way shape or form".
A display merely supporting a HDR input signal and then displaying it in SDR is as worthless as the old panels that accepted a 1080p input and displayed it on a 480p panel: at best making 2HD support" a completely lie, and at worst making the image worse by instructing the source device to send a signal the panel can't properly display rather than one it can. A clipped or crushed (in terms of dynamic range) HDR image on an SDR panel will always look worse than a properly mastered SDR image on that same panel.
