ok , this be not a projector for a office , a classroom , and definitely not for a die-hard videophile for they home theater . the `` pt '' in the pt100 stand for playtime , remember that . but , for shear fun , you can not beat the bang for you $ $ $ fun factor you get from this projector ! I have it set up in my basement project onto a 80 '' projector screen with it connect to a old surround sound system for a very inexpensive but awesome movie theater-like experience ! it easily connect to my Wii -lrb- pretty much design for a Wii since it be not hd -rrb- with the one yellow composite video cable to my Wii and the two audio cable go to my receiver . the movie I stream through Netflix look really good and the surround sound make it all the better for the full theater experience . with all the light turn off , it look awesome ! -lrb- light , even small one , quickly degrade and washout the picture -rrb- . warning : do not bother use the projector 's internal speaker since it be horrible . also , forget about use this in a room with window , sunlight will make the picture impossible to see . for these reason , DO NOT BUY THIS PROJECTOR if you do not plan on USING IT for GAMES or MOVIES in a very dark room with external speaker ! if I have plan to use this in a room with any ambient light and without surround sound or for actually want to be able to read fine print such as use it for a computer monitor , I would have be totally unhappy . overall , buy this for family fun in you basement . this be not a replacement for you tv in you family room but it be well worth the money if use within its limitation . Update : after 9 month half the pixel die . the lamp may last but the lcd display die and you end up with a doorstop instead of a projector .
