To add to this: I run a 32' 4k screen as my sole, external monitor. My M1 air runs it like a champ. I dislike the limit of 1 external monitor, but it does perform well regardless.

Thank you! I'm in the same boat, does your machine work hard and make noise when connected to that 4k monitor?

The MacBook Air makes no noise at all because it has no fan.
