Offering a movie theater-like experience, the H31 features a Pixelworks video scaler, de-interlacer, and advanced HD scaling, significantly optimizing video processing and frame-by-frame smoothness to unleash every aspect of the video as it was intended to be viewed--with any size from 28 to 304 inches.Providing you the ability to tune the image to match the screen, the H31's advanced functions can address issues such as artifacts appearing on one or several of the edges of the image or the need to remove the bars that appear above or below or at the sides of the projected image. These settings can also be stored in memory.
The H31 is HDTV compatible with 720p, 480p widescreen (854 x 480), 1080i, and DVI with HDCP output for maximum clarity. The 850 lumens and four-speed six-segment color wheel ensure superior color reproduction with deeper, richer blacks, detailed nuances, and a full palate of bright colors. The included adjustable color matrix lets you set reds, greens, and blues independently for a truly customized experience.
Other features include multiple quick zoom presets, a digital lens shift with two positional memories, and automatic preset reloading whenever input signal resolution changes. Easy to setup and use, the projector comes with cables, remote, batteries, and more; it is backed by a two-year warranty (90 days on lamp).

It's all about contrast, responsiveness. Not HD, but ED (enhanced def.). Matches DVD quality perfectly. Looks great with Digital over-the-air channels too.
Careful with after-market ceiling mounts, as the magnesium base strips out easily.
By Gus Bahram (CT., United States)
I have to agree with all of the positive reviews of this projector. I too researched this unit extensively online before deciding to purchase it. I am extremely pleased with this unit. Like I said in the title, I purchased this unit in January 2006, and it is still playing great. The main reason I bought this unit was to watch movies, but using it with my X-Box 360 in 720p mode it is spectacular. It may not be as crisp as a plasma or DLP TV, but on a 92 inch screen running with the bulb saver mode, I am more than impressed.

I love this projector. The picture is great. Very clear and crisp.
It looks especially good in HD.
I have had it for almost 2 years now and only one problem. One day the color just went out and I was only getting black and white. The Optoma people took it back and had it fixed quickly.
For the price I would recommend it to anyone.

Five Stars: I am extremely happy with the H31,which I've had for about five months and used for several hours. The service reps promptly replaced the projector bulb,which, fortunately, malfunctioned within the 90-day replacement-guarantee period. The machine has worked beautifully since.
Also, I just bought a $45 Insignia upconverting, 1080i (not 1080p) DVD player and connected it to the H31 using the HDMI port on the DVD player and the DVi port on the projector. (You can buy a single cord with HDMI on one end and DVi on the other, or buy a HDMI cord and HDMI/DVi adaptor separately.) While not true HD, the 1080i capability of both the DVD player and the H31 made for an astounding improvement in the image quality. Instead of being just OK, the image is gorgeous and sharp, with saturated color. One other thought: I made a 6'x6'projection screen for just a few bucks by removing a regular opaque window shade from its roller and stapling it across a home-made frame. While a little awkward to move in from the garage, it does an excellent job.
My old review: The projector did a nice job for about 10 films. It is quiet and pleasing in every way. Problem is that it suddenly decided to shut down completely without warning after five minutes; cools and restarts, then shuts down again. I called Beach Audio, which sells it for Amazon and they referred me to Optoma Tech Service (408-383-3700). The tech said it didn't sound like a bulb problem (I guess I'm thankful for that) and to send it back for service. I've had it for three months and am about to mail it out for service. I'll let you know how things turn out. It should be under service.

I will review this again later when Optoma replies to my suppor ticket, but for now, I cannot give this projector a good rating because the bulb just exploded at 300 hours. I was using this in my clean office, not a dusty room, and took good care of it. I only used it sparingly, not for more than 3 hours at a time.
As for the quality, it was not strong enough in a well-lit room. I had to turn off the lights and put a lamp on. Then it would work well for presentations and movies too. When it was completely dark, it had a nice picture for movies. But now that it exploded after only a few months of use, I am very disappointed to say the least. I just hope Optoma replaces the bulb or I am never buying their product again.
Today I spoke with Optoma, and they will not warranty the bulb past 90 days. So I just got screwed. I don't know if all manufactures have this same policy, but basically the 2 Year Warranty with Optoma is useless since the bulb is not covered. I don't know if I will buy another Optoma or not, but for now, I am not a happy customer and do not recommend this product to anyone.
