The HDMI port on my MacBook Pro doesn't seem to be functioning normally.
When I plug it into the TV, the screen temporarily turns black as if it is connecting to the TV, the mirror connection even comes up and I can see the other display (My Tv) and change the settings.
However, on my TV it shows a
No Signal message. What is the reason for this? When I hook my Xbox 360 up via the same port, it works flawlessly on the TV. This leads me to believe the is a problem with my laptop. It was just working a couple of days ago, and detects the external device just fine. What is the reason for the
No Signal/black screen issue?
