I have that exact same TV with a Mac Mini (Intel Graphics) and
couldn't get DVI to drive it at anything over like 800x600.  The
manual notes that the HDMI inputs are not compatible with computers...
(um even if you get a valid 720p or 1080i timing??? back to the matter
at hand)...  In the end I switched to the VGA input, and everything
worked like a charm.
