A native 1080p projector that crosses the low price-point threshold and balances brightness and color.

Pretty Picture, Rounded Corners

Optoma deserves a big tip of the hat for the image quality performance that the HD20 achieves. I’d say “for the money,” but that undersells quality that I’d really put at two to three times the price, or more than that if you go back just a couple of years. Naturally, part of what makes the HD20 so good is the amazing improvement in the baseline performance of today’s technology, but Optoma has made some good choices as well and the result is a very pleasant image.

For example, I can quibble a little with blues that lean toward green and greens that are a little oversaturated, but Optoma has found a nice balance between brightness and the blended colors that are more prevalent in typical video content. Skin tones are really quite good, as is the balance between black levels and grayscales. Sure, that grayscale range could be a little wider and blacks could be a little deeper, but you’ll find products for a lot more that don’t do as good a job displaying the lower range of grays and shadow details.

So where does Optoma save costs? First, image processing is more modest than you’ll find on more premium units. That means little if the source material is high quality, 1080p or 720p, and the projector isn’t being asked to do much beyond displaying the image. If your primary sources will be Blu-ray players, HD set-top boxes, and good quality or up-sampling DVD players, then the HD20 is going to be a wonderfully affordable solution. However, if the sources are more modest standard definition—particular lower quality composite input—then more problems with jaggies and posterizing appear. I found that the HD20 did do a reasonable job with de-interlacing.

Second, I’m not sure where Optoma’s specifications come from, but it is not reality. I measured nothing close to the 1700 lumens claimed and less than half of that when using the Cinema, Photo, and Reference presets. Even using the Bright mode preset, I was able to measure barely more than 1000 ANSI lumens (1087 lumens). Brightness uniformity is down around 70 percent, and while widescreen projectors always have a more difficult time, this is below average.

Third, the most overt shortcoming of the HD20, particularly for anyone in the business, is an inordinate amount of light leakage from the front and left side of the chassis. I suspect Optoma has allowed this in order to reduce cooling costs (it is a DLP projector and does get hot), but it’s more leakage than I’ve seen from a projector in years and it dramatically affects the ambient room light.

Overall, the fine image quality should outweigh the negatives for most situations and users, particularly where the negatives are fairly specific. For installers, the light leakage will be a minor distraction if it’s in a public area. Otherwise, it might be masked with smart positioning. The same should be true for when quality source material and proper connections are the norm.

There’s a new price/performance champion out there among video projectors and it’s the Optoma HD20. Enjoy the show.
