Similar problem w/ the Mitsubishi 42" projection on the lower right side.

Once again, similar problem since I have a 2" space at the bottom of the 42"
projection TV that has no picture. Overscan loses too much of the top and
sides.

I am about to go buy the pc-tv scan converter that has been suggested on this
list. Although there seem to be a HUGE amount of people that are happy with
their video cards, I am not. I also have the GeForce4 440MX and I have yet to
be pleased. I don't know whether it's my configuration, the large projection TV
or whether I just have super-human eyes. ;-) But I've about given up on the
TV-out.
Hey - if this works, I may just pull the NVidia card out completely and use the
on-board Intel. I'll post the results.
In addition to hopefully fixing my motion problems, this scan converter box has
X/Y positioning as well as over/underscan adjustments. So it should help to
solve your problems as well.
