I had the idea of using a 7" official Raspberry Pi display connected to my Raspberry Pi 3 B+ as a second MM screen. Its function would be to display upcoming events in greater detail. This would also make use of the space that the Raspberry Pi is taking up on my desk (it will be a display/case combination). Is this possible? I was wondering how feasible this would be before buying the display. A few issues I feel may arise would be:

1. How MM would handle different screen sizes
2. Displaying different MM pages on each of the displays

I am new to MM and coding in general, so any input would be greatly appreciated.

Thanks!
