Hello,
I have my 2018 Mac mini attached to an ASUS MG28U monitor. The image is not filling the whole scene. It use to, but it has stopped. When I restart the computer, the page where you put in your password the image fills the full screen, but when it hits the desk top view, huge black bars appear. I have tried scaling it in the system preferences, but nothing seems to help. There is no over/underscan available. Thank you for your time
Hmm... that is not good.
What cable connection are you using?
Go to > Apple > System Preferences > Display > Display tab > hold the Alt (option) key > click on the Scaled button and see if a more suitable resolution is offered.
Go to the monitors menu and try selecting a different Screen Size (aka) Aspect Ratio.
Thank you so much for taking the time to help. I am using an HDMI cord. Could that be the problem. I tried holding down the option key trick, and it defiantly changes the resolution, but not the bars on the screen. I should add that if I restart the computer I get the full screen filled, but once it goes to sleep, and I wake it back up... bars again. Very frustrating.
Aspect Ratio isn’t an option in the monitors menu unfortunately.
