This sounds like it does the same as my 32" Vizio. Mine only accepts
the standard resolutions over HDMI (1080i/720p/480p/480i) so I use the
VGA input instead which allows me to drive it at its native
resolution, 1366x768.

Here's the relevant portion of my xorg.conf on Fedora 10. Take note of
the "ModeValidation" line. I had no end of problems until I found out
I had to add this to get the Nvidia driver to accept 1366 as a valid
width. Since I'm using US based OTA HD I stuck with 60Hz. You may try
specifying a mode like "1366x768_50" and see if it works for you.
