After HS Install Cannot Control Display Resolutions And Other Options

[RadMatty]

My old motherboard was doing great with Sierra but when I installed High Sierra I lost control of my Monitor settings. Now I am stuck with a single resolution of 1024x768. Perhaps there is a Preferences file that needs to be deleted? Any help would be appreciated.

The problem is the same whether the monitor is connected to the video card or the HD 3000 graphics.
