for college , this projector be worth the money . in a sunny day with the blind close on the east window a decent picture can still be acquire . the 16x9 picture be great but when connect to the computer , I sometimes get a greenish tent but not when it be connect to a dvd player , etc. . my only issue be that when watch a movie the projector will go out of focus halfway through the movie , probably because of the vibration of the projector itself . overall a really good product .
