I use Vega 64 and Samsung C27HG70 FreeSync 2 HDR monitor. I have HDR enabled in Windows 10 with SDR brightness set to maximum and HDR is enabled on the monitor over Display Port. Most of the time upon boot, the SDR content is displayed at maximum brightness but sometimes it will be dim again which I know is a common issue in Windows 10. Is this an AMD issue or Windows 10? Any fix?
