How to reset screen setting s Mac Mini, High Sierra

Mac Mini and external screen, changed resolution and now cannot use the screen

I have a Mac Mini and extern screen which is connected via HDMI cable.B y accident I did select a resolution that my screen does not support, and now the screen is black. Is there anything I can do to reset the resolution settings? I tried to reset the PRAM, but that didnt seem to solve the problem.

Mac mini, macOS 10.13

"If you can't change the resolution of your display because you can't see an image, restart your Mac in safe mode to reset the display resolution to defaults.

If starting in safe mode doesn't resolve the issue, reset your Mac's NVRAM and SMC to reset the video ports on your Mac to their defaults."
