do not get I wrong , there be room for improvement but for the price tag this little projector deliver . let 's start with the sound , I agree this projector do not have audio out , but this be not a issue with I , when use hdmus with my laptop because you can use smart audio software to disable the projector audio and send the sound straight to you laptop speaker or external speaker plug in to you laptop . I have Windows 7 and use a p500 Toshiba satellite laptop . I be able to connect this use a hdmus cable to both my DIRECTV HD receiver and laptop w\/hd and get 1080i picture with a 100 + '' 16:9 widescreen within approximately a 15 to 17 foot distance . if you can afford something more expensive I would say go for it , if you be look for true 720p or 1080p hd . however if you be on a tight budget this little projector be great and the picture do not disappoint even for hd . I be so happy I settle for this and do not spend so much more to get a hd -lrb- label -rrb- projector . this be very portable and I be use a regular camera tripod as a stand , and the whole experience be just awesome .
