Decent peak brightness in HDR, slightly better than the Gigabyte Aorus AD27QD. Small highlights in dark scenes stand out, but in bright scenes they aren't as bright as they should be.

For HDR to work, you have to choose the 'HDR' Picture Mode, and set the HDR setting to either 'Auto', or 'HDR400'. For the purposes of our testing, we chose the 'HDR400' setting.
