If there’s one thing we can’t get enough of at TrustedReviews, it’s products that make our minds boggle. Kit that apparently defes the established laws of physics. And it’s fair to say that Vivitek’s D795WT projector fits squarely into this ‘brain bender’ category. Even though in one sense what it does is actually quite simple…
The D795WT’s trick is that it gives you colossal images from absurdly small throw distances. As in, you can get a 90in image from it even when it’s sat less than a foot and a half away from your screen or wall. Getting similar sized images out of normal projectors would need you to sit them anywhere between 3 and 10m away, depending on their lens configurations.
The advantages of the D795WT’s extraordinarily short throw distance are obvious. First, they don’t have to be accommodated right in the middle of the room like many normal projectors. Also, they mean you no longer have to worry about getting special long cables for connecting the projector to your source kit – or moving your source kit into the middle of your room next to the projector.
Minimising throw distance also reduces the potential for ambient light to reduce the image’s brightness. And finally the presence of the projector right next to the image helps if you’re having to use the projector’s built-in speakers, since it means the sound appears to be connected to the picture, rather than some spot three feet behind and above you.
How does the D795WT deliver its amazing image size/throw distance ratio? Mirrors. In particular, right in front of the lens sits a large, convex and aspheric mirror that bounces the image emerging from the projector’s optics back over the projector’s top and onto your screen or wall.
Simple though this procedure sounds on paper, though, it’s traditionally proved very difficult to ally such mirror dispersal technology with really high or flexible image quality. Partly because of geometry issues associated with the mirror system, but mostly because the projector engines at the heart of ultra-short throw projectors tend to be based on LCD tech optimised specifically for business presentations with no thought to catering for a potentially wider market.
The D795WT, though, uses DLP technology, immediately raising greater hopes that it might be a genuine ‘crossover’ short-throw model with as much domestic as business potential.
This potential dual appeal isn’t done any harm, either, by the fact that the D795WT is 3D-Ready (via DP Link system), or by its eye-catching price. We’ve seen it going for only a few quid over a grand, which really doesn’t seem bad at all for what’s on offer. Provided, at least, that the projector manages to deliver some quality to go with its convenience.
The need for a mirror directly in front of the lens does make the D795WT rather an odd-looking beast, especially as the chunky mirror sits so dramatically at odds with the sultry curves of the main bodywork. But the glossy white finish helps, and the mirror appendage at least feels robust.
