The other typical benefits of a laser engine are here as well: 20,000 hours to half-life at rated brightness and no lamp replacements, higher brightness and color stability than you get with a lamp, and rapid power-up and shut down. The net effect is that the VPL-GTZ380 can achieve 100% DCI-P3 color gamut for HDR10 or HLG HDR content at its full 10,000-lumen brightness, without the need of any brightness-robbing color filter. The dedicated red laser bolsters up the deep reds. One of the blue lasers is dedicated to directly reproducing deep blue while the second is put through a phosphor wheel for the remaining blue wavelengths, plus green and red. The light engine uses a clever three-laser system, with two blue lasers of different wavelengths plus a red laser. That is competitive with some other 3-chip workhorse models in or around this brightness class, but much larger and heavier-in some cases more than twice the weight-of the latest generation of "compact" 10,000 lumen projectors targeted at traditional large-venue commercial applications. All of this contributes to a relatively low noise rating of 39 dB and a reduced footprint, but this is still a substantial projector measuring 22.1 x 10.3 x 29.9 inches and weighing 112 pounds excluding lens. The new panels are mated with a liquid cooling system, a proprietary phosphor-wheel in the laser engine with a spiral fin designed for efficient heat release, and a streamlined internal airflow. Like all SXRD projectors, the GTZ380 sports a 3-chip RGB architecture, so you get equal white and color brightness and immunity to rainbow artifacts caused by the sequential color wheel found in most single-chip projectors. The first is a new, 0.74-inch SXRD native 4096x2160 4K imaging chip, used only in this model to date, with an updated liquid crystal material formulated to provide stability at the high 10,000-lumen rated brightness. Some key hardware and software advances help make the GTZ380 possible. Ditto for the well-heeled home theater enthusiast or residential integration customer who has no problem spending as much on a projector as they do on a luxury SUV. Of course, for the corporate, educational, museum, simulation, and entertainment concerns that want huge, highly color-accurate, high-contrast images, a price like that will be all in a day's work. But I first have to acknowledge its breakthrough ticket price: $80,000 prior to adding one of three optional lenses. As I did recently in my review of the VPL-VW325ES, I'll go through the key technologies in the VPL-GTZ380.
