Thanks for the answer KimoProjector. And thanks for the links above. They were very helpful. Unfortunately I'm still a bit confused over this issue. I'm unsure whether it's just reporting the input signal or reporting output as 1080. So I think I'm going to play it safe and just buy a projector with 1080p Native output. That way, I'll know for sure. I'm looking at the BenQ 1200, Optoma HD33, Mitsubishi 3800, and Viewsonic Pro8200. I'll likely pull the trigger on one of those models unless I spot a deal I can't pass on a 1080p closeout. I'm just getting started down the Front Projection road. So I don't want to be too esoteric out of the gate. I am concerned however over the rainbow effect.Edit:
I got the answer to my question from this CNet article.http://reviews.cnet.com/hdtv-resolution/
I'm going with a 1080p native projector so I max out all of my sources like Blu-Ray, HD-DVD, XBox 360 and PS3. And I can max out most broadcasts in 1080i/720p. The W700 really piqued my interest because of the great price...and reputation. Thanks for the help.
