I simply cannot get my new M1 MBA to detect an external monitor. At all.
LG 43UD79, USB C between the MBA and the monitor (using the cable that came with the MBA.)
I've reset, restarted, pressed Option then clicked the Detect Displays button... nothing. This monitor was working yesterday with an older MBA.
Do I need a different cable? Something else?
MacBook Air 13″, macOS 11.0
Are you using the charging cable that came with your MacBook Air? The USB-C to USB-C Cable? That will not work with your external display. Contact LG and they can recommend the right cable to use with the USB-C port.
If you want to use the cable that you were already using with your older MacBook Air then you can get an adapter to work with the old cable and your new MacBook Air.

There is a cable that is designed to work with USB-C to USB-C. That will also charge your MacBook Air from the external Display. That is a separate cable and looks just like the cable that came with your MacBook Air but has other capabilities. Easy to get confused. Good Luck.

Yes, that's exactly what I was doing. The MBA starts to charge when I plug it into the monitor with that cable, so I assumed it would work.
Thanks friend!
