Just want to clarify a couple of things:There is an HDR mode in the settings and turning it on definitely made the colors more saturated. Since this monitor has FreeSync over HDMI that means it has FreeSync v2. All FreeSync v2 monitors are required to support HDR.
- Just having Adaptive Sync over HDMI does not imply Freesync 2. [1]
- A monitor accepting HDR inputs does not mean it can display HDR content properly. [2]
[1] Adaptive Sync over HDMI is an optional component of the HDMI spec. Same as DisplayPort Adaptive Sync existed (intended for low power operation of mobile displays) before AMD created the 'Freesync' branding. Fresync 2 is being treated differently form Freesync: AMD have belatedly adopted the same model as G-Sync and monitors can only label themselves as "Freesync 2" is explicitly certified by AMD. This is to cut down on the spate of 'Freesync' monitors with a functionally useless adaptive sync range (e.g. 48-75 Hz) and no dynamic response-time lookup added just to pad the spec-sheet. The HDR aspect of Freesync 2 also requires games to use AMD's proprietary API, so is not automatically applied and must be explicitly added by the developer. This is mainly down to the terrible state of HDR support in general on PC.
[2] Remember when TVs were commonly sold as "HD capable" or "1080p ready" or similar euphemisms, and turned out to be just accepting a HD signal and displaying it on an SD panel? Same case with HDR. A panel this small and cheap is very unlikely to be using the OLED panel or full-array backlight required to meet HDR brightness and contrast requirements.
