I have do the research about the projector and come up with conclusion to purchase the Viewsonic pjd5122 . the power do not work properly . the light of power button be turn on but the fan do not work and there be no light out of the lense . the speaker also do not work also . the projector keep search for the signal `` signal loss '' all the time . I be so frustrated and call the technical support I be lucky to talk to a tech guy who be physically in India . I still have the problem to communicate with the guy . anyway , I be lucky to return this item back to Circuit city .
