How are you connecting the displays to the MacBook Air?

Do they not appear in System Settings ➜ Displays?

Do you see anything on each display?

Provide some details and someone may be able to advise.

13" MacBook Airs and MacBook Pros with plain M1 chips only support one external display.

So is your "MacBook with M1" actually a 14" or 16" MacBook Pro with a M1 Pro or M1 Max chip? Or are you using some sort of second-class workaround, based on a technology like DisplayLink, that requires installation of a third party driver to get a signal from any video output driven using the workaround?
