A quote from the article:
Today, we’re looking at our first HDR-capable gaming monitor, BenQ’s EX3501R. It’s a 35” VA panel with an 1800R curve, 3440x1440 resolution, FreeSync to 100Hz, and HDR10 support.BenQ EX3501R VA Curved FreeSync HDR Gaming Monitor Review
BenQ EX3501R delivers a smooth immersive experience in fast-paced action titles. It supports HDR10 just fine but doesn’t offer as much contrast as some of the competition and has a little less color saturation in HDR mode. For SDR material however, it has few equals. While there are faster screens out there, few of them look as good.
