As someone with the OG steam deck, and an HDR TV that my main PC and PS5 are hooked up to, I have issues all the time when streaming HDR content to the non HDR display on the steam deck. It tries to convert the image to standard dynamic range, but just blows out the whites and crushes the blacks. I always gotta remember to turn HDR off on my PC before streaming, but it would be really nice not to have to do that.

Try Sunshine + Moonlight and this script:

Already using Moonlight and sunshine so half the work is done for me. You just made my day, thank you!
Edit: Had to update my version of Sunshine, but once I did that, this did the trick. Thanks again!
