RE: Set up 4k HDR External Monitor Output for Dell Precision 7720??
Excellent! Fyi, from what I've read about HDR, if you enable it in Windows, everything that's in SDR (non-HDR) looks a lot darker in order for HDR to be rendered properly, and since the vast majority of applications are still in SDR, that's not a setting you'll want to leave on permanently, and you'll probably want to make sure you run your HDR applications full-screen, otherwise anything else will look wrong. Good luck!
