Best way to set up focus/color/tint/contrast

[joeseattle70]

Everything is going great still with the TV since it was repaired. The technician dialed in everything but indicated I'd need to adjust to suit my preference (color/focus/tint/contrast). Do most of you set this up using a DVD signal, or a cable tv signal? There is a definate difference between the two. Thoughts?

I suspect the answer is to just adjust them to fit the source I'd be using the most, but wasn't sure, so thought I'd ask.

Many thanks!
