Summary: I read so many good reviews that I was certain that I am buying a good product, but it has been less than 6 months and it's already dead. I had a much cheaper HP projector that lasted more than 5 years. I think the bulb went out. I used it only couple of hours per week so not sure how the bulb can go out so quickly. I think I might have received a returned/used product since the packaging tape looked like had been opened and re-applied.
Summary: I bought this projector in the middle of last year replacing an Epson 6100. This is my fourth projector, the first being a Sony 720p CRT, the second an HP6120 720p DLP I bought new and the third the Epson 1080p LCD that I bought used. The HD33 out preforms the Epson in every way but the black level and then only marginally. The super sharp picture and vivid color are great for my Home theater with a totally light controlled room that was a former bed room only 12 x 12.
Pros: Very sharp, excellent color control,FI,outsanding 3D with RF,IR or DLP link for glasses and reliable proformance.
Cons: Average 2D, poor black level, no lens shift, DC2 and no iris
Summary: An excellent projector for the money. Optoma HD33 has excellent sharpness and colors and very nice 3d. PC Gaming was very good as well. Unfortunately I wound up returning to Amazon due to seeing rainbow artifacts, or color flashes due the the spinning DLP wheel. I purchased this projector from Amazon chiefly due to their excellent return policy.
