why can't my brightness be adjusted?

Hi, I experienced the same problem. You can try going to System > Display > HDR and then I enabled Auto HDR and under SDR Content Brightness, the brightness slider showed up and I was able to slide it to change the brightness vs. the brightness slider in the home page. I hope that helps, and that my explanation was correct.

Hello,

I understand your frustration. Here are a few steps you can try to troubleshoot the problem:

1. Restart Your Computer
2. Check Brightness Settings: Go to Settings > System > Display and ensure that the "Change brightness automatically when lighting changes" option is turned off.
3. Update Display Drivers: Outdated drivers can cause issues with brightness control. Open Device Manager, find your display adapter, right-click it, and select Update driver.

If none of these steps work, consider reaching out to Microsoft Support for further assistance.

I hope this helps!

Unfortunately this isn't working on my laptop, everything is updated already, I don't have the option to uninstall the driver without disabling the device and I'm kind of concerned that disabling the GPU might make it very difficult to enable it again if my screen goes off.

What else am I able to try?
