Yea I said this before, the one thing that would get me excited about a new model would be a big bump in brightness while maintaining at least similar contrast. That's really the one place I feel my 540 is still lacking. I'm using my HP screen for that reason, but I'd really like to go back to my original 126" screen. Oh and also I would like to do that in a lower power mode to keep the noise down. I can do all of this with the HP screen, but it's only 106".
