Window layouts by monitor: how each big screen works on a Mac
By Guido Crego · Last updated:
Big monitors behave differently on a Mac: some get sharp Retina scaling and some don't, some reach their full refresh rate over one USB-C cable and some don't. Each page covers one model: how it works with macOS, and window layouts sized for that screen.
If your monitor isn’t listed, the general guides cover the same ground: ultrawide monitors and a different layout on each monitor.
