my concern with this projector be that it be very marginal for my intended use . the resolution of the projector be only 800 x 600 and when project smaller type figure they project so fuzzy that they be almost unreadable on the screen . Epson 's tech support be very good however and they isolate the problem for I and finally suggest that I need to upgrade the projector for what I be try to do . for someone want to use the projector for power point presentation with very large letter it would be ok or for project just photo or video it work ok . for my use however , I buy cheap and pay the price in it be utility .
