@peemee Interesting discovery. A rather expensive external display, but if you happened to have it lying around unused, it seems like a good option. I've never owned an iMac—my first Mac was an Intel Mac mini, with which I used a third-party external display. The Intel iMacs aren't too expensive now used, though, at least not here in Japan. Most everyone wants the flashy new colors and the Apple silicon models, even though the displays (Retina) on the newer Intel models seem just as nice.
