It's not as simple as that with my Samsung F6100. With the Intel driver in its default automatic mode and the TV input tagged as "PC" it depends on whether it is a CEA mode or not.

Booting a desktop linux with 60Hz the HDMI link is in sRGB mode and the desktop looks normal. Changing to 50Hz with xrandr or Kodi sets the HDMI to BroadcastRGB and the desktop looks a bit odd, but the video image is good. The only defect is that 59.9Hz is sRGB when it should be BroadcastRGB according to the HDMI standard.

If the TV input is tagged as "STB" the connection is always BroadcastRGB.

With the passthrough driver mode active, it is quite broken in 60Hz "PC" mode because the driver forces BroadcastRGB when the TV and HDMI standard require sRGB. I expect that is why the Intel developers are not interested in the passthough patch.

Passthrough should only be active when both the source and destination require BroadcastRGB
