I have a 2015 iMac 5K 27" and a 27" LED Cinema display, side by side now.This is being replaced by an M1 Max 16" soon, so I'm looking for a new monitor solution.
My plan is to use the 16" display of the MBP along with my desktop monitor, so no matter what I choose, I'll have the "dual monitor...
If I have a 4K display scaled to 2560x1440, what should the dimensions of my wallpapers be if I want the crispest background possible? Will 2560x1440 wallpapers look as crisp as the scaled UI on a 4K monitor with native dimensions of 3840x2160? Or should I strive to download 3840x2160 wallpapers?
