I am contemplating getting a new projector to get my Lumens up to where they really should be. What is the difference between 1080P and WUXGA? I am assuming that 16x10 vs 16x9 will give me a little bit more width...is that all? Will it cause handshake problems since it is not 1080P native, but supports 1080P? I am looking at a BenQ MU686 3500 Lumen projector.
