Re: Best 1080p Projector for Sports?
I believe the consensus here is "there is no one correct answer." DLP seems to be what is being recommended, but there are several options, even within that category.
I love watching football as well as movies, and my room dimensions and screen size are similar to yours. Because I was not going to ceiling-mount, [at least not initially] I did need placement flexibility. I ended up going with the Sanyo PLV-Z5, which is a 720P LCD model. I bought mine last year. This year, you might want to go with 1080P, although many sports programs are actually native 720P, and you could save some serious cash if you went that way. I have no complaints with sports or movies. If you are able to completely control the lighting of your room, and don't sit too close to the screen, my personal opinion is that LCD gives exactly what you want, more bang for the buck.
Good luck. Either way, you're going to have an awesome theater. There's just nothing like a big dedicated room with a great projector! As a matter of fact, I think I had better get down to my theater now.
