Connecting Projector to MacBook Air
I have a Sanyo projector connected to my MacBook Air via VGA/thunderbolt. The computer is recognising the projector, and the screen display is altered, suggesting that the two are speaking to one another. However, try as I might, I cannot get my computer screen to appear on the projector. Any suggestions please? I need to have this sorted by Monday. Many thanks. I am using Monterey.
MacBook Air 13″, macOS 11.1
