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-preview-36...
Brightness dims dramatically after user login upon KB5030310 installation on a PC having AMD Radeon RX550/550 Series as graphics card. Driver version of AMD card is 31.0.12027.9001. I have tried uninstalling the previous mentioned graphics card driver and issue would be fixed until its automatic reinstallation. Let me point out that before user login brightness is normal and it drops off after logon. Brightness is minimum for the whole display except of the arrow of the mouse cursor. For the time being I have uninstalled the above mentioned windows update and issue is fixed.
Waiting for an update fix either from Windows 11 part or from AMD part.
Thank you in advance

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

@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.
Regards,
Nikos

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.

Same here with RX590. Sometimes the screen stays bright after login, but sometimes it is dimmed. I can enforce the dimming when going to System Settings -> Display (in this case the screen always dims). What fixes it for the current session is to switch of the monitor and switch it back again.
Changing the color depth didn't help for me (changed from 10 bpc to 8 bpc).
Monitor is attached via Display Port. I've also tried another cable. No luck.
I have a second monitor attached via HDMI. On this monitor the issue doesn't occur.
Hoping for a fix from MS and/or AMD soon.

You can try activating (if available) HDR setting Control Panel -> System -> Display -> HDR. This setting would eliminate the dimming effect but at the cost of making all colors appear abnormally saturated. HDR setting for my case is unavailable now that I have rollbacked back the problematic windows update but it gets available and inactive after its installation. When I activated HDR dimming would be gone but color saturation really annoyed me so that I preferred to uninstall the update.
Hopefully this workaround may be helpful to someone.

@ngeorgopoulos Thanks for the hint, but HDR is not an option. I can activate HDR only for 1 monitor (the one which is connected via DP), but not for the other, so the colors look totally different between both monitors. I still haven't understood what's so fancy with HDR...

Hello and hope all is well. I had the same issue with brightness/darkness.
Installed latest window update on 5 machines, 3 desktops, 2 laptops. All went well except on one desktop where all three attached monitors came up very, very dark - on all machines, desktop icons now had shadows. Uninstalled the MS update, KB5030310, rebooted, all was well/back to normal.
Reinstalled the update, KB5030310, same issue. Uninstalled, back to normal. Set window update not to download and install any updates.
Noticed another update on another PC was avail, KB5031354, let that download/install, same darn issue, monitors got very dark....hmmm...what the heck was going on?
My video card is a AMD RX580. Had not updated the adrenalin software in 6 months, didn't see a reason to...got me thinking...so updated to 23.9.2, reinstalled KB5031354, crossed my fingers, rebooted...and all is GOOD.
Seems the answer is to update the video drivers/software suite, at least on an AMD Radeon card. Oh yeah, the other pc's all had their video drivers updated before the window updates were applied - all AMD Radeon machines.
Oh, the desktop icon shadows have not gone away.....still there on all 5 of my machines, yes, tried registry, everything, nada.
