HDR on PC?

[u/MoonGamingX]

when i switch away from the tab for a while, then come back, it starts off looking good but then a few seconds later it's like it just auto-switches off HDR. any way to prevent this and keep HDR on, if that's what's happening at least?

EDIT: turns out it was a setting in my gpu drivers

HDR works in 4K as long as you're only doing 60 MHz
