Optoma H31 Features & Favorites
We get asked fairly regularly to review more budget-minded products for our readers. In particular, everyone seems fascinated by the influx of lower-priced front projection systems that are competing for a large financial portion of the home theater display market. These front projection systems promise large viewing screens with an almost unbeatable price point. Compare, for example, a 92" front projection DLP system vs. a DLP-based rear projection unit and you are talking a potential savings of over 60-70%! It doesn't take a Nobel Lauriat to figure out where the bargain is. Sure there are trade-offs, mostly in terms of ambient light management and viewing distance, but if you can overcome these obstacles then you are looking at a tremendous opportunity.
DLP Projector Strengths
The strengths of the DLP format, at least in its current iterations, include good black levels, phenomenal color saturation, great lamp life (for the format) and full digital readiness with HDCP-compatible HD M I or DVI being readily available on most contemporary models. The format has an easier time with black levels than typical LCD-based systems due to the way the D M D (digital micromirror device) is able to turn away from the lamp and deny light to the screen. Recent advances have produced HD2+ technology (dubbed DarkChip2) which reduced the gap between mirrors, removed the dimple where each mirror is attached to its post, and provided a light-absorbing coating on the back of the micromirrors which together allows for better contrast ratios and black levels. In fact, this new technology is supposed to offer a 20-25% improvement in overall contrast ratio - with the most gain being in the more difficult-to-achieve black levels. Couple this with a 6-segment color wheel spinning at 7200RP M (4x) you have a nice projector that gets the job done with a minimum of compromises.
Features and Favorites
The Optoma H31 has a host of excellent features and functions that makes it a tremendously configurable entry-level home theater projector as well as an adaptable one. Here are a few of my particular favorites that stood out on initial use and inspection:
- 5 Calibration Modes per Input
Each of five modes, selectable by the User, are able to be calibrated for each input. This means that you could choose to setup up different settings for Day and Night viewing in addition to a special setup for, say, daytime sporting events that require the maximum brightness and color saturation at the expense of contrast. You could also set up a fourth mode for black and white movies, with a color temperature approaching 5500K for a more realistic presentation. The fifth mode - pure gravy. And this is per each input!
- DarkChip2 Technology
The ability for this projector to reproduce deep black levels was impressive for a digital display. We were able to get decent real-world contrast ratios out of the H31 as well as produce compelling scene details on darker theatrical scenes.
- Fully Backlit Remote Control
With only a few minor suggestions, this could be the greatest projector remote in existence. While you will probably not use it very often, unless you are unfortunate enough not to have a great universal remote control, the wireless remote that accompanies the Optoma projector is as ergonomic as it is attractive.
We'll expand on these features later, but Optoma's attention to detail (down to a convenient carry-bag that comes with the H31) makes this system a very compelling argument in the face of the choices one has in entry-level front projectors.

…I think the setup disk might be the way to go for me, is the avia better than the essentials setup dvd? I was trying to save myself the step and the $. I am fairly new at all this, i was not sure if I just adjusted the brightness and contrast levels and left the advanced adjustments alone if the picture would be clear and crisp…
IMO, the Avia setup disc is a bit easier to navigate than DVE. I own both however. Considering the time and money you've invested so far, the costs of the DVDs are well worth it. I doubt you'll need to go into the advanced measurements area. Between contrast, brightness, color, tint, & sharpness. You'll more than likely be very satisfied with the picture. Since you are just starting out, the truly advanced measurements are best left to trained A/V professionals.
Welcome to Audioholics, you'll find a ton of information and experienced folks here. Don't be afraid to ask.a
I understand that everyones room is different and some settings would be different, I guess I am trying to get some input on brightness and contrast levels, as well as the rgb brightness and contrast levels. I think the setup disk might be the way to go for me, is the avia better than the essentials setup dvd? I was trying to save myself the step and the $. I am fairly new at all this, i was not sure if I just adjusted the brightness and contrast levels and left the advanced adjustments alone if the picture would be clear and crisp. Some specs on my system, I have a DIY 115 inch screen and my projector is back 18ft, everything is dvi and hdmi, ps3(bluray) and I have a yamaha rx-v1700 receiver, with full B+W surround sound, expressvu HDTV.

Yea I just completed a review of a $6,000 receiver
Let me know when you need help with that Denon pre/pro and amp
Using someone else's setting can make the image display look worse, not better. The avia setup cd takes about 15-20 minutes if you take your time. I have the H30 and I usually adjust my every 250 hours on the bulb.
I am also looking for calibration settings for the h31, if anyone can be of assistance that would be great.
