I have the same set.
The best you can get is 1080i.
If you want to get 1080p, you will have to get a HDMI Xbox360 or loop it through a upscaling 1080p amp if you've got one.
Erm, I don't think that's quite right. I've got the Sony W2000, which is the model down from the X and I'm running my Xbox at 1080p via VGA.
VGA is a progressive only cable, interlaced signals cannot be carried by VGA.
More info can be found in the Xbox FAQ
2 HDMI's are taken up by PS3 & PC.
Wait what? HDMI ...PC? You can connect a PC trough HDMI? Could you tell me more about that please?

As for the other 2 persons who replied, thanks. Yeah I don't feel like spending another 450$ on an Elite just to get 1080p as I already have a preminium XBOX360 that works great.
How does exactly HDMI splitters and 1080p amp works?
some of the more recent nvidia graphics cards have hdmi as well as dvi
