Projector Reviews

During a panel discussion at the recent Home Entertainment 2003 show in San Francisco, a few of the panelists (including me) indicated that, despite all the new flat-screen imaging technologies found in front projectors, rear-projection TVs, and plasma and LCD monitors, our preference was still for images created by CRTs. A manufacturer's representative on the panel retorted that CRTs were fine in their day, but that his company was in the business of providing the nearest thing to a theater experience in the home—and CRTs just don't cut the mustard anymore.

It's easy to visualize the operation of a CRT projector: three tubes, each operating much as the picture tube in the TV on your kitchen counter, flashing overlapping red, green, and blue analog images onto the screen. If you have a good model in top operating condition, and if you or your installer have slaved over its setup, you'll see an incredible picture—one that, on a home-size screen (not so large as to accentuate a CRT's main limitation of light output), is still as good as home video gets.

18.1 foot-lamberts. This light output would be impressive for any front projector. What makes it amazing is that I measured 18.1 ft-L on a 7.5-foot-wide (100-inch-diagonal) Grayhawk screen with a 0.9 gain. If you were to use this projector on a 6-foot-wide (82.5-inch-diagonal) Studiotek 130 screen (which has a gain of +1.3), you'd get an almost-blinding 48.6 ft-L. With that kind of light output, you'd be able to use a screen larger than 12 feet wide (165 inches diagonally) and still have a bright, watchable image. And that's in the low-power mode.

To a videophile who cut his or her teeth on CRT units, a 7-pound video projector that is no larger than a fat dictionary and can be mounted inconspicuously on a ceiling or table is hard to believe. It can even be stored out of sight and set up again, when needed, in minutes. How good can it be?

The CRT is a relatively stable, mature technology, but the new digital projection systems, particularly Texas Instruments' Digital Light Processing (DLP), are moving targets. Last year, DLP really came into its own for home theater with the introduction of TI's HD1 Digital Micromirror Device (DMD). Not only did the HD1 have a true 16:9 widescreen aspect ratio with 1280x720 resolution, but DLP projectors based upon it were significantly better than earlier designs, particularly in the depth of their blacks.

The Sony VPL-VW12HT is the latest version of Sony's flagship consumer LCD projector. In appearance it's a twin of its pre-decessor, the VPL-VW11HT (reviewed in the July/August 2002 <I>Guide</I>). Its 16:9 LCD panels have the same specifications. It will accept all of the most common source resolutions&mdash;480i, 480p, 720p, and 1080i component or RGB&mdash;and scale them to the panels' 1366x768 native resolution. The user can select any of the most common aspect ratios: widescreen (anamorphic or letterbox), 4:3, and several others, including two that pass the source through without scaling. There are six programmable video memories to store different setups, including picture adjustments, color temperature, and aspect ratio.
