EPSON EX3200 Multimedia Projector -lrb- v11h369020 -rrb-  it come with a usb cable and all you do be plug it into you computer but that be where my problem start . there be no software disc to install but when I connect the computer a install icon appear for installation only my computer keep lose the signal from the projector cause the screen to turn blue and blank after call tech support twice for solution `` change usb cable '' which do not help and install software from epson website which would not work because the latest software have already be install I be ready to return the projector to Amazon with some choice word especially after the last tech person tell I if I want to use the projector I would have to disconnect and reconnect it to the computer every time the signal loss cause the screen to go blank . sound ludicrous right ? but have a modicum of intelligence I uninstall the latest version software and reinstall the older version software from epson website and the projector work like a charm . I have a imac run a 10.6.8 os x and a Macbook pro 10.6 os x. so the projector do all that it be suppose to do once you get past the software installation process . it would have get 5 star without that fiasco .
