Hello, I recently just bought a Mac Mini and have recently been having trouble with the display resolution. The default display resolution is 1920 x 1080 but It looks a bit blurry and doesn't correctly fit the screen so I changed the resolution to 1366 x 768. I have recently been having a problem where whenever I wake my mac mini up from sleep, the display will automatically underscan and so each time I wake up my mac, I have to go to settings and reset the underscan setting. I searched this issue online and it says that it might be a problem with the NVRAM or SMC, but I also saw that on silicone chip macs, it automatically checks for any issues and resets if needed but I am not sure if these facts are valid. Thank you.


P.S. I attached a screenshot of the display setting menu and for some reason, It says that 1366 x 768 is the default resolution even though it normally says that 1920 x 1080 is the default.

Mac mini, macOS 13.2

Hi Jaceved_jr1,


Welcome to Apple Support Communities. We understand that you're having an issue with the display resolution resetting when your Mac mini wakes from sleep. We'd like to help.


To first answer your question, a Mac with Apple Silicon does not need to physically press any keys to reset SMC or NVRAM. These are refreshed when you shut down and restart your devices.


Then, to continue troubleshooting this issue, we'd recommend that you connect with Apple Support directly. Since your Mac mini is the newest version, they may have some specific steps to help with something like this. You can start that conversation here: Contact - Official Apple Support


Hope that helps.

Take care!
