I am looking to buy my first projector, and I am leaning toward DLP. I like the X1's reviews and price, but I am worried about my low ceiling(6'8" tall) and my screen being too low, due to the big offset of X1. I want to run it in 16:9 mode with a 16:9 screen. How will this look with the X1? What's this light spill I read about? Projectorcentral.com says there is "no degredation of signal" when using keystone with DVD's or HDTV. But is there a limit to how much I can cheat my screen up by tilting projector and using keystone? Thanks for any info. you can give me.
