I have a new 16" MBP M1 PRO and I'm trying to use an external display in clamshell mode WITHOUT it being plugged in and it's not working. I'm on 12.1. I know the old laptops had this limitation but I thought it wasn't an issue with the M1. I hope there's a solution because I don't want to carry my charger around when I connect it to my TV or other screens. Thank You in advance.
