#Targa + Underscan
Actually I think my problem is with the centering on my card. (Just a
guess). Because I can't see the leftmost and rightmost edges on my
monitor, I have difficulty setting the centering. About 4% of the left
side is out of view and about 2% of the right. I have fiddled with the pot
on the back of the card to get my centering close. I did some captures
once that were laid back to tape and the registration was way off, so I
tried to adjust it with the screw on the back. It helped, but I really
need to work on it some more. Probably the easiest way would be to setup
the card on a monitor that will switch to underscan so I can see all of my
edges and center accordingly.
