Brightness dims after user login upon KB5030310 installation on a PC with AMD Radeon RX550/550Series
- 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.
I have the same problem which occurred after the KB5030310 update. My video is via Display Port on a RX570 card to my screen. I did spend some time with support who implemented two optional updates as well as added a SYSTEM Policy key to correct the issue. I seemed to and worked normally after the second Restart. But after shutdown and booting up this AM the issue is back I restarted once after getting this. Oddly I find Window 11 does NOT provide me a screen brightness control and my display's brightness setting has no affect. I have the bright cursor as well but the main screen is quite dim in comparison. I was thinking of doing a RestoreHealth via DISM tool I have used on Windows 10 but refraining for now. My search found this post on it which is dead on. My MB is an ASUS x570 Plus w/Ryzen 7 CPU.
Good Luck
I was going to paste as screen shot but not valid here.
- 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).
- This is the only workaround that works for me as well. After rebooting I need to go back in and toggle bit depth. Annoying so hoping a fix on this soon.
- Should add that my fix doesn't persist after reboots, but that doesn't bother me as I leave my PC on 24x7.
- To 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.
- Same behaviour as described above multiple times.
MB: Asus Prime Z790-P
GPU: AMD Radeon RX 580 (connected though DP)
After uninstalling KB5030310 brightness was restored to normal levels. I don't find that option to change colour depth to 12bpc. Maybe monitor related? (Mine is MSI Optix MAG342CQR)This morning on restarting it was dim again and only brighten by toggling another display setting which immediately fix it. If this persist I likely uninstall the update.
Is that what you did as I don't have brightness bar anywhere to move either in Win 11 or the AMD Software I have running.
- I just uninstalled the update. I'll wait for a fix before I reinstall it.
My pc doesn't have a brightness bar as it is a desktop pc. I use the app F.lux to manage my brightness on my pc but I quickly ruled out any part in this issue.
Ron_W399 thanks for the info... for the time being I have uninstalled the problematic update and I'll be waiting for a potential fix on a next cummulative update. If I'll get the same problem over again I'll definetely test your proposed solution. Just a question where can I find the options of Gaming selection that you mention? Is it on Win Settings or where else?
Thank you very much for your time posting your workaround.

Nikos
