I just updated from a 2014 Mac Mini to a 2020 Mac Mini for work. When the old computer was connected to this monitor, everything looked great (connected via display port).
Now when I connect the same monitor to the 2020 Mac Mini (via HDMI), it looks pixel-y, and the windows and text look a little larger than they should.
In System Preferences > Display, the resolution that the computer reports is correct for the monitor (1920x1080) and none of the other resolution options make it look any better, even after viewing the additional resolution options by pressing 'option.' I've already tried rebooting the computer and rebooting the monitor separately. Edit: I also tried resetting the display settings using the Cmd+Opt+P+R combo on startup and that didn't help either.
I don't have any other cables on hand to check if the HDMI cable is the problem, but I just bought this one. What else can I try?
As a side note, I'm also having problems with the keyboard. During setup I had to go through a process of keyboard identification, but now my 'control' or command key is not working as it did before.
Any help would be appreciated.
