I have a Sony Bravia TV and since the very beggining some models of this band and few others invert the HDMI colors if the input was not providing RGB 4:4:4 Pixel Format PC Standard (Full RGB) output.
The manufacters never updated the affected models and they won’t see that as a issue. So my solution to every device I have is to output the video in RGB 4:4:4 Pixel Format PC Standard (Full RGB).
