Why cant i change the tint of my picture? the menue keeps skipping the tint option
If you're watching UK TV broadcasts then we don't have a need for tint. Similarly, with HDMI sources you shouldn't need tint either because the TV's colour decoder isn't active.
Tint is a throw-back to the American analogue TV system called NTSC. Their system doesn't lock the colour phase to the sync signal. So depending how far the TV was from the transmitter the colour would be further and further out of whack. Hence the industry joke that NTSC stood for Never Twice (the) Same Colour ...N - T - S - C. The Tint control was used to re-time the colour signal. The UK didn't have this issue because our TV system (PAL - Phase Alternate Line) includes information to lock the colour signal phase.
Strictly speaking, Tint is only required with NTSC analogue composite signals. This is where the brightness information is mixed with colour on a sub-carrier frequency. So, that would be signals via an aerial lead or from the yellow video connection which is how most of us first see a composite signal. These signals are encoded as NTSC. Any signals where the colour and brightness (luma) information is kept separate shouldn't need Tint. So, S-video, Component and RGB at 60Hz all bypass a TVs NTSC decoder. If the TV is correctly designed then the Tint option should not be available. Some TV manufacturers break the convention though, for the simple reason that many old school US consumers grew up adjusting Tint, so it's too much of a culture shock to take away that feature.
To recap then, if Tint isn't available then it's because the signal doesn't need that adjustment. The colour timing is already bang on accurate.
