Summary: Absolutely love it, been 3 or so weeks and the clarity is perfect, even on a textured wall; brightness is awesome, even with lights on. For darker scenes, definitely need to close curtains and shut off lights, but that is expected from projectors. It get's abnormally warm, must be well ventilated!
Summary: One of the best projectors for a great price. I use it for my home theater on an 80" screen. HDMI works great. Automatically can convert to 3D mode. HD quality is excellent. 1080p quality is excellent. Easily adapts to a ceiling mount. Only down side is when running a TV tuner (with digital antenna connected via coax) the tuner cannot go through the receiver (via RCA) which I have going out to the projector via HDMI.
Summary: Anyone else have a lag when streaming videos from a mac/macbookpro through AirPlay to their Apple TV's on this projector, or projectors in general? This is a great product, and works with Apple TV nicely, I just wish it didn't sometimes lag. It might just be my wireless internet, not sure. Any response is helpful. I also got a Soundfreaq bluetooth speaker (doesn't sync with Apple TV :p) but I plugged the audio cable into the back and the sound is a lot better!
Summary: Based on the satisfied customer feedback on this site I replaced an older Optoma 1080p with the Optoma H180X. As others have noted the picture is very clear and bright and much better than the older Optoma. The picture detail is actually better than my 46" 1080P LCD that I can view almost side by side with the H180x projecting the same image. I am very, very satisfied at this price point. Looking forward to trying the 3D capability.
Summary: very impressive picture. I mounted it from the ceiling 12 feet back and it projects a excellent 100" picture. The manual zoom and focus along with the remote keystone and lens shift allowed me to center the image perfectly. It looks awesome when the room is dark but still looks pretty good with the lights on while we're playing pool. Its very quiet and the audio is adequate on its own but I'm planning on adding speaker to enhance that.
