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 pass-through 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

I had problems with pass-thru driver mode as well. With some media, I noticed that small black bars would appear at the top and bottom of the screen when the pass-thru switch occurred. I think that the TV was padding extra black lines at top and bottom when the video switched to a lower frame rate from pass-thru. The media was 1920 x 1080, so there shouldn't have been any change in aspect ratio. I ended up turning the pass-thru feature off.

@n2vwz: Nope ... not at all, fix your underscan / overscan settings.

@lateadapter: Interesting ... but wrong ... as your TV ignores the infoframe, it does not care at all, so - yes - quite broken in that regard. Never plug a android box on this TV.

"Broadcast RGB" <- such mode does not exist - it's a setting to control the intel driver ... there is only Full Range and Limited Range info frames in the intel driver.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.
