Just bought one of these from QED. Basically I have two queries about this tv: This is my first post so please no flaming if the answer is obvious. 1) about the vertical position of the picture. The picture doesn't seem to be centered vertically. When I watch a program that fills the screen there seems to be more space at the top then at the bottom. Is there any way of changing this? The only settings I can find are for adjusting the angle of the picture. 2) The default channel the TV turns on to is 1. I have a Tivo and DVD player connected. I don't watch tv via normal aerial. Is there a way to get the TV to turn on to either AV1 or AV4 by default? Any help appreciated.
