I have an LG DLP. It has the same story. If I connect via the HDMI then it
will accept all resolutions. The RGB input really is for VGA format input
and restricted.

One gripe I have with my LG is that they are lying about the resolution.
It says 720, and specifically gives 1280x720 in the manual, yet is does
not have that many pixels on the screen (you lose significant part of the
margins). Do you know that your model (which one?) truly shows the full
1280x720? With my machine in text mode I would lose a few characters off
each line, making it very hard to use.
