As far as Video in is concerned it has RCA and RF.
It has little (read nothing) in the way of adjustment (as far as I am aware) for AV mode.
ANYWAY, I do intend to upgrade it just not yet.
UNTIL I DO, I have just purchased a DSE signal converter to take the DV-I (VGA) from my Video card and stick it into the Video in (RCA) on my TV.
But it flickers (badly).
The TV does not flicker from the feed from my Sky box, nor does it flicker from any of my other video sources. It also works great on the video feed from the PS1 (yes PS1).
