> I have the 47 inch Westinghouse monitor.  I don't use a modeline in
xorg.conf at all.  X.org automatically detects the resolutions available
from the monitor.  For the VGA input on my monitor there is a menu where you
can adjust the picture position and whatnot.  I think the refresh rate
problem has to do with the RAMDAC of your videocard.  1920x1080x50/60Hz is
pushing lower end RAMDACs to the limit.  Hopefully a DVI cable will clear up
your overscan problem.
