I'm not really sure how to diagnose whether this is a hardware or software issue. I have a 2020 MBA and I'm outputting via an Anker USB-C to HDMI adapter to a TCL 6 Series 4K TV.
Everything looks good and works and I can output 4K @ 60Hz, but when I display video in full screen from the Apple TV app or Quicktime player and it's letterboxed, the letterbox is pink instead of black and the rest of the image has a slight pink cast to it as well.
Moving the mouse to bring up the UI snaps the letterbox back to black and the discoloration of the image clears up, but as soon as I let the UI hide again it snaps right back to pink bars.
Anyone got any theories? I don't even know how to test if this is a hardware or software issue.
