12. What About HD?

We chose these three projector models for their undeniable video quality, but also because their 1280 x 720 imagers give them compatibility with certain HD signals like 720P and 1080i. But finally, is that really worthwhile? The problem lies in the fact that most DVD players send a progressive 576 signal. That means that the basic resolution of DVD is below the native resolution of the projectors, which are capable of displaying 720 lines. That's no problem where the picture is concerned since individual pixels and the screen-door effect are less visible when the imager's resolution increases. That was confirmed for these three products - we were able to make out no such effects with a 8.2 ft. (2.5 m) diagonal at 11.5 ft. (3.5 m) from the screen.

Yet this small advantage doesn't always justify the price difference between an 800 x 600 or 1021 x 576 imager and a 1280 x 720 system. If you really want to optimize your video projector in the absence of HD sources, there are currently only two valid solutions. The first is to buy a top-of-the-line external processor capable of up scaling your 576 signal to 720P. But the price of these little gems puts them out of the range for most.

The second solution is a DVD player capable of doing the up scaling internally. You can find models priced anywhere from $500 up to $1,500. The results you'll see on the screen can be fairly spectacular, depending on the player, and you'll need to spend around $1,000 if you want adequate up scaling that won't deteriorate the original signal. But the investment is worthwhile if you're planning to buy a projector capable of displaying 720 lines natively - unless you're already getting enough HDTV program sources to satisfy you.

The Winners

The Sony VPLHS51 has the best quality / price ratio, hands down. Available at less than $3,000, it's an excellent tri-LCD video projector that, for once, won't make you regret not buying a DLP. Associated with a top-of-the-line DVD player connected via HDMI, it'll give you unforgettable movie-watching experiences. And its ease of installation and short focal length make it suitable for most rooms. 

If you want to go one notch higher in terms of performance, the Optoma H79 offers unbeatable performance for all types of use. Do keep in mind that its location will have to be carefully thought out, though, and ideally it should be installed by a professional. But in any case this is a product that's usually sold by specialized resellers who can provide service to match its $6,000 price.

The Mitsubishi is also an excellent product, with performance that's very close to that of the Optoma, while its price puts it at a disadvantage. Mitsubishi has lowered its price for the projector somewhat, but not enough.
