This is correct. Not all sets that are able to handle an HD signal
(720p or 1080i) are able to *resolve* all 1280x720 or 1920x1080 pixels.
These sets are approporiately called EDTV (enhanced definition TV),
although they're able to handle HDTV signals.
For example, my BenQ 20" LCD TV can handle 1080i signal, but it's only
an 800x600 resolution LCD panel.

Yes, this is very typical.
There are LCD panels that have native 1920x1080 resolution, for example
the Sceptre X37SV-Naga
I believe Sharp is or will have LCD displays with the same resolution.
For plasma, if you go up to the larger sizes (50" and greater), they're
either available now or coming.
Many (most?) rear projection LCD and DLP-based sets have a native
resolution of 1280x720. There are some exceptions. HP has a DLP-based
rear projection set that has 1920x1080 resolution and I believe Sony has
a LCD-based rear projection set with the same resolution.
Hope this helps,
