after spend week research different projector I finally decide to go with this one , and I could not be happier ! I pair it with a 120 '' screen I also buy on amazon . I have the projector mount on my ceiling . the whole project be a little bit frustrating , I be try to get the screen hang and the projector mount in just the right way . but after I get it up there I realize I way over complicate the whole thing . the keystone adjuster fix the mount angle with just a quick flick of a button . but even with all my little trouble it only take I about 2 hour to get everything set up just perfect , hidden wire and all . so no bad at all . the quality of this projector far exceed my expectation ! this be my first projector , and I be use it in my living room as a main view screen . so I run everything on it , my tv , computer screen , gaming , dvd , blue ray ... my living room be pretty dark so ambient light be not much of a problem during the day , and at night the picture be still very watchable even with all the light on . my friend love come over and enjoy my new `` movie theater '' . its be a blast for play game like call of duty and halo on as well ! the picture be just amazing ! I definitely recommend this projector for anyone who want a amazing picture and do not want to spend thousand of dollar do it .
