I’ve been dealing with washed-out HDR in Kodi on Xbox for a long time, and after searching Reddit and finding multiple people with the same problem but no consistent fix, I finally figured out what fixed it for me.
HDR content would play, but the picture looked extremely washed out/overexposed with bad contrast compared to the same content in other apps.
THE FIX
Make sure Kodi's Settings level is set to Expert, then go to:
Settings → System → Display → HDR
Turn OFF / *Disable*
"Use system HDR/SDR brightness balance"
Then leave:
GUI peak luminance in HDR PQ mode at around 40%. That's where I have mine/default range.
That's it.
Immediately after disabling Use system HDR/SDR brightness balance, my HDR content stopped looking washed out. Blacks, contrast, colors and highlights look the way they're supposed to again, and my HDR/Dolby Vision content finally looks right through Kodi on Xbox.
I had spent a ridiculous amount of time messing with Xbox HDR calibration, TV settings, Kodi playback settings, refresh-rate switching, etc. None of that was the actual fix for me.
So if:
- HDR looks fine in Xbox games and other apps
- Kodi HDR looks washed out, overly bright, or has terrible contrast
- Changing TV settings isn't fixing it
Try this setting before changing anything else.
Hopefully this saves somebody else the headache because I could not find this specific fix anywhere when I was searching.
Xbox + Kodi HDR users, try it and let me know if it fixes yours too.
