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

Same problem, all dimmed but the cursor, with Radeon RX 570 (using windows drivers) on dual monitor setup- Only main monitor has the dimming problem, second monitor does not have the problem (both using displayport). The problem did not appear with KB5030310 , it appeared instead with KB5031455 but uninstalling it did not fix the problem. Switching off and on the monitor fixed the problem.

Same here. With me the problem started with the KB5032190 Windows update. Since on the same computer Linux works flawlessly, it is obviously a Windows-problem.
Problem description: the screen dims a few seconds after Windows has started. The only way to still work with the computer is to active HDR-display (with its ghastly bright light). The other option that seems to work at the moment: start windows -> go into "Sleep" mode -> wake computer up -> Display working as normal.
My system details:
Windows Edition: Win 11 EducationN (64 bit)
Windows Version: 22H2
Grafics Card: Radeon RX 570
AMD-Adrenalin: 23.19.05.01-231017a
Last cumulative Windows 11 Update: KB5032190
Neither updates to the graphics card, or the device-driver, have made a difference. For me also re-booting, and turning the monitor on/off have not helped. Very frustrating.

Just to confirm, I am experiencing the main screen dimming issue from today - I have a Ryzen 5 system and Radeon RX580 graphics with two monitors, the main monitor being 4K and HDR capable but with HDR switched off due to photo use. Both are calibrated. For reasons best known to MS, I have yet to receive W11 23H2 but W11 Pro 22H2 22621.2715 was fine until today's cumulative updates KB5032190 and KB5032007. Now it has the dim main monitor issue - which can be fixed only by the workaround of booting, then putting the machine to sleep and then waking it. All is then fine unless you look at the display settings, at which point you go back to dimness.
Looking forward to a fix for this annoying issue.

Have you tried to go to sleep, and then wake up your computer. That solves the problem for me. Bloody annoying - but it works

@geostra still no news unfortunately. I still have to turn off and to turn back on my monitor after every logon. Still waiting for an action from Microsoft and/or AMD.

@ngeorgopoulosStill the same here - putting PC to sleep and re-waking works for me, including correct custom colour calibration, but a frustrating workaround. I see that the AMD Driver and Software are dated 17 October 2023 so I suspect an update is imminent - nothing from MS.

@APBX100S Probably. HDR is a messy thing, especially on computers. Also RX 500 series has very shoddy driver support, and everyone in this thread seems to be a 500-series owner.
Not sure how to fix it without forfeiting your calibration, but for me personally the dimness got temporarily fixed when I tried turning HDR on & off with the keyboard shortcut (Win + Alt + B), but it dimmed again right away whenever I opened Windows's Display Settings.
So, if this works for you, having to re-do the keyboard shortcut trick every time you wanna go to the settings could be an okay workaround for the time being until either AMD or Windows fixes the issue.
