I buy this for new comer briefing for my business . it look good but that be about it . none of the input work . after follow the instruction and plug in a VGA cable to start with , there be a `` no sync '' screen showing . then I try different input include hdmus and s-video to no avail . I have own a few projector and this be product be just a waste of money . I end up purchase a pocket projector with the build in hard drive and good battery life -lrb- mpro150 -rrb- .
