Summary: I own the this great projector from when it first came out aprox 5 years ago. Then i paid a good part 5 grand for it and well worth it. Still with the orignal lamp and all other parts. The 1080P images are amazing,some of the best i have ever seen. Only time i would ever replace this PJ is if we started broadcasting in a higher res than 1080P, or if 3D really takes of.
Summary: If you buy this series of projector from Optoma (or any Optoma projector for that matter based on my internet search of similar projector problems), you must be aware of the problems listed in the reviews posted here. I am currently experiencing similar problems that have already been described in prior reviews. My barely 3 year old projector has a great picture and looks great on my 100" screen when it works, however it is currently not working.
Summary: Personal Experience I did a lot of research before I bought this projector back in early 2008. Before buying the Optoma HD81-LV I had been to two CES shows in Las Vegas where this was the flag-ship model at the Optoma booth. At those shows it projected a fantastic image on one of the larger screens used by competitors at CES.
Summary: I purchased this unit in August of 2007. It produces an outstanding picture when it works, but has been returned to CA for repair twice - both times resulting in multiple weeks without the unit. The unit overheats in the cabinet we had built for it (we have had extra fans installed, special air conditioning and still can't close the front of the cabinet) and shuts down.
Summary: Personal Experience excelent adjustment , color,gray scale,size,contrast etc. little noise in normal,less in economy. almost excelent Problems no switching in autto for hdmi, sometimes,the iris closes unexpected.. maybe needs some firmwareupdate. .
Summary: I bought ours about a year ago. We enjoy watching movies in HD and this projector delivers stunning results. We have created quite a complicated set up, with dvd player, multi media computer, dvico tvix streamer, home theater receiver and hdtv tuner connected, with all this working both on the tv screen and on the projector. The one problem we had was that right after 2 months the remote simply stopped working, and I was never able to get another one.
Summary: The image from this HD81 projector from a 1080p source is stunning and with so much details. The 720p/1080i images are likewise very detailed and incredible. The connectivity is just so flexible and convenient due to the outboard scaler unit. Speaking of scaler, it's a like a high end scaler capable of de-interlacing 480i materials flawlessly. Even my old laserdisc is looking good with this projector.
Summary: Personal Experience I replaced my Infocus 7205 with this unit and I'm very happy. The picture is to die for crystal clear. Problems I have not had a single problem and I have had it for 8 months!!!
Summary: I bought this projector and scaler back in March 2007. I had it just over 3 months when it developed a problem. It was coming up with a lamp error although it was still putting out light. Even though Optoma originally told me that it was a lamp problem, it was not. I had to send it in to Malpitas, CA to have it fixed. I had to pay for shipping (because it was days older than it's poor 3 month full warranty) and insurance.
