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...
- I 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.
(1) Problem: Similar monitor dimming situation
(2) Graphic Card: Asus AMD RX550 4G EVO (I tested Asus nVidia GT710 graphic card which did not have the dimming problem)
(3) Temporary Solution (after many many hours to testing again and again)
(3-1) Use "Display Driver Uninstaller" (DDU / free software) to clear all nVidia and AMD graphic card drivers (under windows 11's safe mode) in my PC.
(3-2) Install AMD Pro Edition 22.Q4 driver (choose driver only) (I did test several AMD graphic card drivers issued date in 2023. They all work similar as Pro Edition 22.Q4 ) The monitor came back normal (no dimming issue)
(3-3) I checked "Windows 11>color management>device>monitor" and found setting to be "sRGB IEC61966-2.1"(default)
When I checked the box "Use my settings for this device". The dimming situation cameback. Unchecked "Use my settings for this device", and rebooted PC. The monitor became normal again.
This means you CAN NOT use your own color management icc setting. (I tested Windows 11's manual color management calibrite procedure. Dimming again)
(4) We need Microsoft / AMD engineers' help. Please hurry-up.

- I reinstalled the KB5030310 update and the dimming reoccurred.
After some messing around a bit, I figured out that if I put it to sleep and wake it back up, the problem consistently goes away.
Can anybody figure out why this would work?- Yeah, hopefully MS will correct this in a release for November. Currently I either wait until it appear fully loaded before turning on the screen or shut off then back on. I am posted above in 2nd post Sept 28th. My card is RX550.
This will make me think twice about installing preview releases now.
