MBPro 2019 model with up to date Catalina - External Monitor sleeps when closing the lid on laptop
When I close the laptop, my external monitor will stay on for about 5 seconds, then goes to sleep. I can't get it to wake-up. Only way is to open my laptop monitor about 1/4 way open and it will come on again. Had this problem about a year ago, reset SMC, NVRAM, and it has been working great. Just moved laptop to my other desk, reconnected, same monitor, same setup, and it's not working now. Any ideas on next steps? Thanks!!
