I have this exact TV with that video card displaying over VGA myself. For
awhile, I used the DVI port on the card to the HDMI input on the TV, but the
TV thinks anything coming in from ports other than it's VGA port has
overscan, so it cuts off about 5% of the screen on all sides, which is
fixable from Myth, but a pain none-the-less. I switched back to VGA because
I could not tell any difference in quality between VGA and the DVI/HDMI
cable, and I didn't have to mess with overscan. I tried for a long time to
get a modeline that would work for the DVI cable to auto-resize the whole
screen, desktop and all, but was unsuccessful.
I have the screen displaying in 1080p from the VGA port and I've thought
that it works great, the video card has no problems with it. I've had no
need for a modeline, but you should be able to use what Rich has written
(Modes "1920x1080_60" "1280x720_60" "720x480_60"), without having to
specify the whole modeline...
If you do end up finding a modeline that works better for the display,
please e-mail the list or just me about it because I'd be curious to know...
