Brightness dims after user login upon KB5030310 installation on a PC with AMD Radeon RX550/550Series
Hi everyone, I would like to report an issue after installing KB5030310 (OS Build 22621.2361) available at https://support.microsoft.com/en-au/topic/september-26-2023-kb5030310-os-build-22621-2361-p...
- Nov 26, 2023I found a temporary solution! Just turn on the HDR then set the "SDR content brightness" slider to minimum, turn off HDR and voila, no more need sleep to have normal brightness. I'm now on 23H2 with RX560.

Similar fix for me. This only happens on one of my two display, so for the affected display, I used the AMD Adrenalin software to change the display from 10-bit to 8-bit (which fixed the problem), and then changed it back to 10-bit again. (The dimming problem is not limited to KB5030310).

Should add that my fix doesn't persist after reboots, but that doesn't bother me as I leave my PC on 24x7.
- ngeorgopoulosOct 12, 2023Copper ContributorTo sum up so in either case, dimming effect persists after reboots and it is a matter of preference whether you want to turn of and back on the display or change color depth from 10bit to 8bit and back to 10bit. As far as I can understand in either case something is resetting back to normal and dimming is gone. Thank you all, so we just have to wait until it is fixed by some Win or AMD update. If anyone finds out that there is a final fix drop us a line please.
