By Brian Straight on October 17, 2006
I have owned an Optoma EP 719 XGA projector for about a year and find it an impressive unit for the price. However, when Optoma released the HD 70, a full 720p projector, for under $1000, I had to buy it. The projector is light, but substantially-constructed with a sturdy gloss white case. I was immediately impressed with the quality of the build.

I wasn't too sure what to expect--after all, it had half the rated lumens of the 719 and offered a gain of about 33% in resolution on a 16:9 movie. I plugged it in, attached my HDMI DVD player, made some minor adjustments--and was amazed at the result. The HD 70 provides a bright, crisp, high-contrast and richly-colored image that was in every way measurably superior to the 719. Standard DVDs take on a 3-dimensional look; my wife even asked if I had bought a high-definition DVD player because the images looked so sharp. The beginning battle sequence of Star Wars III is simply breathtaking; the opening "dark" scenes of "Harry Potter and the Goblet of Fire" take on a rich depth, with lots of hitherto unseen (on the 719) shadow detail available. I project on a 106" Grey Wolf screen.

The HD 70 achieves this by using some advanced technology--and it works, most of the time. The Image AI function boosts contrast to an astonishing 4000:1 by varying the light output of the projection lamp based on the scene displayed. This function really does deliver, although it can be a noticeable distraction at times. In the scene in Apollo 13 where Lovell is discussing the fire that killed his colleagues with his son, Image AI seemed to be a little "lost" and there was noticeable and almost constant adjustment to the lamp brightness. In most cases, however, the function performs admirably.

Just received 2 days ago to replace my 480p Infocus 4805 and am very happy with the step up in resolution. Much quieter than my 4805, better picture, and HDMI input are the biggest advantages so far. Seems to be very solid, light but not flimsy. Zoom and Focus dials have a little tension which makes it easier to fine tune. Great remote and easy setup. IMO the best 720p projector you will find on a budget.

I just installed this a few days ago. I haven't gotten around to writing my review till now because I've just been transfixed like a mogwai staring at the screen.
Before I ordered the HD70, I was considering the less expensive optoma H31. The H31 is only capable of projecting a 480p image. The HD70 projects a 720p image.
If you are looking to buy an entry level DLP projector, you may have to make the choice between 480p and 720p. I also used reviews from a site called projector central to make my decision.
Other germane observations about this machine:
-It's quiet. The cooling fan is not audible even during quiet movie scenes.
-It's compatable with a ceiling projector mount that cost around $40 +S/H. Google "mountdirect" to see the universal "PMS series projector mount" that I bought. Looks like Amazon's selling a mount for around $70 if you want to go that way.
-Simple remote. It allows you to adjust the contrast, picture dimensions, etc. However, the focus and zoom are adjusted with wheels on the projector itself.
If you need a little more information, head over to the projector central website. The tests and reviews seem pretty comprehensive out of all of the stuff I read online.

It will work well till you right your initial review - but soon after the warrenty period was over the color wheel started to have problem and screen will flicker with alternate colors. Initially, I had to stop it and restart (pain full wait in between as it wont start again right away) to get it to work. Later it required cleaning the dust from inside to get it to work say 30min. Family was getting frusted a lot. A 1000$ unit originally not lasting few years was very very disappointing.

Finally decided to send it for repair (150$ min cost to look at it). I was asked to replace the wheel (~90$) and that did not fix the problem. I sent it again (another 150$) and this time I was told to pay another ~500$ to replace the mother board.
Very poor quality and un-affordable repair costs. Customer service was not able to offer much help to salvage my investment. Never again Optoma anything for me.

Ended up getting a Epson for ~450$ (less than Optoma mother board cost) and happy with it as it has 1) air filter 2) no delay between stop and restart 3) sliding lense cover. Pls look somewhere else and also google Optoma color wheel issue before buying.

I've had my HD70 about 3 months now, and I'm still blown away. I work as a projectionist in a movie theatre and I've been playing with Video Projectors for a long time and bringing them home to test. I also show 16mm and Super 8 films in my living room and nothing until now ever came close to the look of real film. I have mine mounted on the ceiling, but I do have very high old Victorian Ceilings, so the off set was not a big deal, plus the mount I bought adjusts very easily. I use about 7ft of my 9ft wide pull down screen so the full 16.9 image is about 7 x 5 feet. (I never cared for that silly salesman diagonal inches crap). Even with the bulb setting in economy and all the fancy AI Image stuff turned off, this projector just blows me away. Some one mentioned not being able to find the right screws to mount this projector, I just took the Manuel to the local True Value Hardware store and asked the guy if he had these screws. He walked over to a big wall full of fasteners and gave me exactly what I needed and told me to come back if they didn't fit. Something to be said for supporting your local Mom & Pop stores when ever you can. I also bought an HD tuner and an upscaling DVD player. Over the Air HD looks fantastic. I watched most of the World Series in Hi Def this year. I can't imagine what 1080p looks like. Oh and yes, the beginning of Star Wars III is the closest we can get to the pure digital signal on regular DVD so far, and it is amazing on this projector. It's a great sequence to show off your machinery. One thing I might mention... when you blow up an image this big, you are going to see the imperfections of lesser resolutions.Read more ›
