I tried everything you suggested. No change. I had also reinstalled the Radeon driver to no effect. The odd thing is that a couple of days ago when I was fiddling around I did something that allowed me to "roll back driver" and that made Night light work OK; then I accidentally hit "Shut down" instead of "Hibernate" and next time I stared up the issue was back. I'm not sure just what I did to be able to access "roll back driver". It seems I may need a previous version of Radeon.

Download and install the driver from this link.

Thanks for your quick response. Unfortunately I got an error message that my operating system does not meet the operating system requirements. I have many gigabytes free.

Have you tried to rollback the driver again? If the issue still persists, try re-installing the operating system and check if that works -

1. Shutdown the computer.

2. Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.

3. Press F11 once for System Recovery.

4. Choose the Keyboard Layout.

5. Click on Troubleshoot.

6. Go to Recovery Manager and click on System Recovery.

Note : Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer.

Let me know.

I didn't like the idea of a complete reinstall so I looked for a work around. First I entered "gamma" in the search bar and found I could control the brightness by turning the gamma down using "Calibrate display color". This helped a lot but left me with very dark shadows in pictures and videos. I looked for an app to download and there are many. On the site "Raymond.cc computers made easy" was a list of 10 free tools and a suggestion to try the AMD Catalyst Control Center which is accessed by right clicking on the desktop. Under "Desktops and Displays" I opened "My Console Displays", then "Display Color (Built-in Display)" and found sliders for color hue, saturation, brightness, contrast, and color temperature. Not as simple to use as Night light but it works great.
