So I got me an early Christmas gift. Disclaimer: This is not just AMD actually but could apply to Nvidia as well as Intel. I bought me a Samsung CRG90 the 49 inch beast. The 5120 x 1440 Freesync 2 HDR 1000 nit peak. Anyhow with win 10 with HDR enabled games would be dimmed, washed out or insanely bright. And menus would be so dark you could not see them. I earnestly started trying to work on these issues yesterday but I bit ago I had a eureka moment and decided to check a a few things. Using CRU I looked up the colorimetry and metadata for my CRG9 shocked at what I found. My expensive Samsung 1150 USD monitor did not have any HDR metadata associated it with it. Well hell I can fix that with CRU though I am pretty pissed as should not have to fix such an issue with this expensive of a monitor. So I tried MD0 which worked, then I tried MD1 which worked even better for me. Now this is only part of the fixes that were needed. Some games require HDR to be toggled off in win 10 to work correctly for example Assassin's Creed Odyssey while Far Cry 5 requires HDR toggled enabled in win 10 to work correctly. So we kind of need a list of HDR games and if they require the toggle on or off in windows. Lastly we need to adjust the SDR content appearance slider under windows HD color settings in display All this fixed everything up for HDR and now I can even see youtube giving me HDR options as a display option as well. While I should not of had to add the metadata type for this monitor, it did fix me right up and now everything looks great.
