    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 just fixed mine. Haven't rebooted but although I don't play games I went into Gaming selection, Display and toggled Colour Depth from 10bpc to 12bpc. The screen brightened dramatically. there is no brightness bar anywhere in Window 11 or in the AMD Software.
    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.

      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.

      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
