I am using my Mid 2011 iMac Sierra 10.12.6 as a monitor for my M1 2020 Monterey 12.5.1. I bought apple cables and it works. Except on my 27″ it does not use the whole screen. Just the center 50% or so. Was wondering if it could my apple cables or if there is a setting that I could change. Thank you.
I just like the large screen of my 27″mac. I use many spreadsheets and it is more efficient for me on the imac. Thank you.
