Problem with 16" MacBook Pro and External Monitor - Seems to widespread on Apple Discussion Boards
Having an issue with an external display (LG UltraFine 5K Display) where sometimes the MacBook Pro doesn't recognize that it has the display connected to it. This is usually when it wakes from an extended sleep. I have to restart the MacBook Pro, disconnecting and reconnecting the cable doesn't seem to help. It is connected via the Thunderbolt 3 cable that came with the display (uses one cable to charge and feed video). I have the display set as my primary display with menu and the MacBook Pro is the secondary display. Prior to this display I had the original Apple Thunderbolt Display that I connected with an adapter. Same thing was happening, so I thought it was the display and adapter, which is why I purchased the new display. Tons of people having same issue with different displays. One user got a replacement MBP and same thing happened. Anyone else have this issue or a solution?
