Mac Pro 16" left side HDMI out not working - screen flashes and does not connect. Right side works fine. Multiple adapters tested including apple offical
Today I bought an official usb-c to HDMI adapter as I thought this could be the issue... but its not.
As the title says, when connecting to the 2 right USB-C's the external monitor connects fine.
When connecting to either of the left 2, the laptop screen flashes on and off as does the touch bar icons. It does this flashing indefinitely and does not connect to the external display.
Could it be a hardware issue?
