My Late 2016 MacBook Pro with Touch Bar has problems! My internal display works only in a certain angle and doesn’t display in the 90 degree angle. I have been using the same system using Airplay through my Apple TV and also using an external Display. However not able to figure out the exact reason for the display not functioning.
Both the 13” & 15” 2016/17 MacBook Pro Touch Bar systems face the same issue its dubbed FlexGate! Apple encountered a design defect that only showed up later in use with these systems displays. The cable that connects the display to the logic board backlight logic fails. Sadly, Apple has not fessed up on this defect and you’ll need to get your display replaced out of pocket, Ouch!
