External Monitor Resolution Options
I just updated a Mac Mini to Catalina, and now my external display resolution is cutting off the Top/Bottom sections of the screen. So, I can no longer see the icons on the Dock (set to bottom of the screen) nor can I see the Menu items on the top of the screen. When I go into the Display Preferences and press the Option key while clicking on 'Scaled', none of the options work with my monitor. My display (32in Magnavox TV) has 1366x768 resolution, but none of the options work. I've even tried 1080p and 1080i with the same result. This was working before the update and I can remember the ability to adjust the screen scaling, but it seems to have disappeared. How do I get my display to properly scale to show the entire screen?
