Hope someone can help out there. For about the last 6-9 months since some spurious Windows or Nvidia driver update, I have noticed that if I enable HDR within Windows 10, ANY game set to exclusive Full screen mode will force HDR on, regardless if the game supports HDR or not. Needless to say any game that does not, looks terrible. The only solution I have found is to disable HDR within Windows 10 when playing these games or switch HDR mode Auto to off on my 4k TV (Sony), effectively disabling HDR. Prior to having this problem games not supporting HDR would switch off HDR when going Full screen perfectly fine. Its not a massive deal but from searching online I am not seeing any others complaining of this issue. I have tried various things to fix this but with no success. Just wondered if anyone else was seeing the same issue?
