I spent a bunch of time and a few dozen reboots and launches, each time trying just one thing different on each reboot until I think I hit on a successful and reproducible way to get HDR functioning properly. I had no idea what I did, but something was causing HDR to start functioning. Thing is: every so often while playing with HDR settings, suddenly ShadowPlay would start working in HDR and would then continue to function normally until I restarted my PC, at which point it would be completely broken again. I occasionally create content for Destiny 2, and thought I'd start doing HDR until I ran into this. I found a fix and this one actually works.īackground: I recently got the AW3423DW monitor, and have been giving HDR gaming a go, when I ran into the problem of ShadowPlay being massively overexposed when attempting to record something in HDR. So I did a ton of searching on this and came up with nothing but totally unhelpful, non-working, or completely out of date Reddit, YouTube, and GeForce Forums posts.
