LATEST ADDITIONS

Runco upped the 3D ante at its press conference with the new D-113d dual-engine projector system. Each 3-chip DLP engine includes twin UHP lamps, which means even 3D images have plenty of brightness—the company claims it can fill screens up to 420 inches diagonally. Instead of linear polarization to separate the left and right images as in the D-73d, the new model uses spectral filtering similar to Infitec/Dolby 3D, though this system was developed by Panavision with five spectral bands rather than Infitec's three.

For those who are challenged more by space than budget, Runco's new LS-100d can be mounted flush to the wall directly above or below the screen, taking only 18 inches of depth and producing a 92-inch image. Its LED light source turns on instantly and will last 50,000 hours while consuming 70 percent less power than a conventional lamp. It ain't cheap at $20,000, but that includes an outboard DHD4 video processor.

Really big 3D in the home no longer requires a special projector—with the Image Anyplace 3D Passive Viewing Kit from Flexible Picture Systems (FPS), you can display passive-polarized 3D using any pair of conventional projectors, providing greater brightness than single-projector systems. The 3D signal from a Blu-ray player or broadcast source is sent to an HDMI splitter and then on to two IA3D processors, which separate the left and right images. These signals are sent to the two projectors fitted with polarizing filters in front of the lenses. The IA3D processors also provide advanced geometry correction derived from the Silicon Optix Geo processor, making setup and alignment surprisingly easy. The kit includes two IA3D processors, HDMI splitter and cables, polarizing filters, 10 paper glasses, four plastic glasses, and a remote for $7495. Just add two projectors and a polarization-preserving screen, and you're in business.
