Not much else to say, I never use an external monitor or anything like that. I was working, closed my macbook, did some stuff, opened my macbook, black screen. I have reset the pram, the smc, shut down restart, but now the only way I can get it to do anything is with my bluetooth trackpad/ keyboard, and using the hdmi through usbc while the whole thing is closed. If i open the macbook while plugged into the monitor i get the blurred version of my desktop background, but the laptop screen itself stays black. Any suggestions?
