Hi Benjaminnnnnn,
Greetings!
Thank you for posting in Microsoft Community.
I'm sorry to hear that the night light feature did not work as expected. I appreciate the effort in performing the troubleshooting methods.
Please also perform the methods below:
- Force the device to restart. Press the power button for 20 seconds while the device is turned on.
- Try to sign-out then sign back in. Go to Surface logo > Find the profile's logo > right-click then choose sign-out. > check if the issue still persist.
- Run the Surface Diagnostic Toolkit.
- Run the System File Checker.
- Refresh the Intel Display driver. Go to device manager > expand Display adapter > right-click the display adapter then choose uninstall > restart the device.
- Install the drivers package manually.
- Check the specific OS build of your Windows Settings> System> About.
- Download the driver and firmware for Surface, choose Surface Pro 8 and click download on the next page.
- Please choose the .msi file that matches your current OS Build and click Next.
- After the download, runand installthe .msi then Restart the Surface Device
- Try to update the PnP Monitor (Standard). Go to device managers > Expand Monitors, right-click the active "PnP-Monitor (Standard)" > Click Update Driver > Browse my computer for driver software > Choose "Generic PnP Monitor" > Finish everything, sign-out and sign back-in.
Let me know how this goes.
