The latest illumination options create more versatile home theaters.
At the heart of JVC’s DLA-RS10 home theater projector are three 0.7in. 1080p D-ILA devices (JVC’s version of LCoS), a new optical system that uses wire-grid polarizers, and a native contrast ratio of up to 32,000:1. The DLA-RS10 comes with a 2X lens that has a three-step fixed aperture. It boasts an advanced HQV Reon-VX processor by Integrated Device Technology (formerly Silicon Optix) and a 2X motorized zoom lens with an auto dust cover to give you 1000 lumens brightness.
In addition, bringing THX-certified performance to your home theater, JVC’s DLA-RS20 projector includes a new high-precision 17-element motorized lens with an upgraded optical path. Its three-panel D-ILA light engine produces 900 lumens brightness with a 16-step fixed aperture.
Finally, JVC also offers its 4K projector, the DLA-RS4000, for home theater. For maximum performance, the DLA-RS4000 has a patented five-element, 100-percent-glass, fully multicoated optical design corrected for chromatic aberration and astigmatism in standard home cinema environments.
It’s the unique calibration capabilities of Kevin Knoll built in to every unit that makes the home theater projectors from Knoll Systems special. The company’s HDP-1100 short-throw model features the DLP 16:9 MaxPlay DMD chip (1920x1080); Nikon lenses; manual 140 percent up, 60 percent down, and 15 percent horizontal lens shift; and ± 15 percent horizontal and ±30 percent vertical digital keystone correction. With an 850-ANSI-lumen light output at a 3600:1 contrast ratio, Knoll’s HDP-1100 short-throw projector has a 1.34-1.65 short-throw distance (1.25X zoom), and it comes with a lamp rated at 2000 hours (3000 hours in whisper mode) and a 33dBA noise level.
Knoll Systems’ HDP-1200 long-throw projector outputs 950 ANSI lumens at a 4400:1 contrast ratio, the same kind of lens shift and digital keystone correction as that of the HDP-1100, and the same Knoll calibration and processing for the best performance after installation. Like its short-throw brother, the HDP-1200 can put out a true 2.35:1 image with the addition of an anamorphic lens.
Putting out a whopping 10 megapixel (4096x2400) ultrahigh-definition display from three 1.27in. diagonal 4096x2400 D-ILA chips, the Meridian 810 Reference Video System delivers beyond-cinema-quality images, exceeding the resolution of some commercial digital cinema projectors. Using a brand-new light engine with a PKI xenon lamp, its up-to-4000-lumen output delivers SMPTE cinema reference level for reflected light (16ft.-L) from gray or white screens and a 10,000:1 contrast ratio thanks to its organic polarization grid. The 810 Reference Video Systems are fine-tuned at Meridian’s facilities over four days using exclusive calibration technology developed by William Phelps. The system boasts interchangeable lenses in short-, medium-, and long-throw packages including a motorized 2.35:1 anamorphic lens. A very-short-throw package is also available.
Mitsubishi’s new 1080p HC7000 and HC6500 3LCD premium projectors are available exclusively through custom home theater system integration and high-end retail channels as part of Mitsubishi’s Diamond Series line. The HC7000 HD projector boasts 1000 ANSI lumens at a 72,000:1 contrast ratio, and the HC6500 outputs 1200 ANSI lumens at a 15,000:1 contrast ratio. Both provide anamorphic lens Modes 1 and 2 support, giving you either 2.35:1 or 16:9 aspect ratios, and both incorporate the HQV high-performance video processor, the Reon-VX video processing chip. They also come with two HDMI version 1.3 inputs to provide easy setup options for multiple video inputs. With a lamp life estimated at up to 5000 hours in low mode, Mitsubishi’s HC7000 and HC6500 let you change the lamps through an easily accessible lamp housing without disassembling the mounting structure.
Just this month, Optoma is bringing out the first 1080p DLP projector for less than $1,000, the HD20, which comes with two HDMI inputs and provides 1700-ANSI-lumen brightness at a 4000:1 contrast ratio. Optoma’s HD20 is going to expand the audience for sharing big-screen movies and sporting events or for taking your videogaming to the next level by connecting this 1080p projector to your favorite game console.
At the high end, Optoma’s HD8600 is built around a single 0.65in. 1080p DMD DLP chip, and it features interchangeable lenses and an enhanced PureMotion engine with the latest ME/MC processing from Pixelworks. The HD8600 offers extended Pureshift (full vertical [0 percent to 120 percent] and horizontal shift [±10 percent]), has three lens options for the most flexible installation placement, and is 2.35:1-compatible when equipped with optional anamorphic lens kit BX-AL133B.
