For simulation apps, the DLA-VS2100U from JVC performs with 850 ANSI lumens, 10-bit gamma correction and a seven-axis color management system. More than 700 of the first-generation VS2000 models are currently installed in Level D simulators worldwide. With a 1920x1080 native resolution produced by three active matrix 0.7in. sim-specific digital D-ILA devices, the projector provides digital smear reduction via black frame insertion. Using a 220W ultra-high pressure lamp with a 3000-hour nominal life to 50 percent brightness, the DLA-VS2100U dips to only 0.9W power consumption in standby mode. The unit has a wide range of installation orientations and control options include IR, serial, and LAN.
LG Electronics offers the CF3D LCoS passive 3D projector with dual engine, single lens technology for a range of applications including industrial 3D CAD rendering and home theater. The projector sports a fairly wide assortment of video input formats including VGA in/out, composite, and component along with three HDMI ports. The imaging system produces native 1920x1080 resolution and a choice of 16:9 or 4:3 aspect ratios with a light output of 2500 lumens in 2D and 1250 lumens in 3D adjusted with a 1.3X optical zoom. Additional features include auto source selection, advanced digital keystone correction, and 120Hz TruMotion technology. A 3D auto picture calibration algorithm helps maximize 3D effects by automatically adjusting brightness of the left and right images.
A primary 3D home theater entry for Mitsubishi Electric is the HC9000D using high-def SXRD imaging panels to produce 240-frame operation for active shutter glasses. A separate liquid crystal panel reproduces each of the primary colors, and there is a range of display modes available. The unit displays a 16:9 aspect ratio and can illuminate a 100in. screen from a distance of 11.2ft. to 20.6ft. Video input ports include analog RGB, two HDMI, composite, S-Video, and component. Remote control options include IR and a 9-pin serial port. The system uses a 230W high-pressure mercury lamp and power consumption drops to 7W in standby mode.
The DLP 3D-ready NP216 projector from NEC offers 3D home theater users a 2500-lumen light output in normal mode, native 1024x768 picture resolution (1600x1200 maximum), a projection distance of 3.9ft. to 38.4ft. and a 1 to 1.1 zoom with manual focus. This model also provides built-in closed captioning, a Kensington lock slot, and 10-step magnification with location control. The Macintosh-compatible unit includes two 15-pin RGB inputs along with composite and component video connectors. The audio section contains 1/8in. mini stereo inputs and a 7W speaker while external control options include RS232 serial, IR, and wired LAN.
Optoma brings 3D projection and interactivity to the boardroom with the TW675UTi-3D WXGA ultra-short-throw projector. Designed to upgrade whiteboards, screens, or even blank white walls into an immersive learning experience, the unit comes with a full version of Qwizdom WizTeach interactive software and provides 3200 ANSI lumens at a projection distance from 5.5in. to 11.5in. from the projection surface with a diagonal picture size of 77in. to 100in. There is a VGA monitor loop-through along with inputs for HDMI v 1.3, VGA, S-Video, and composite. Audio inputs include both line and mic level connections. 3D compatibility includes 120Hz frame sequential 3D for resolutions up to 720p, and it offers 60Hz field sequential 3D for resolutions up to 480i.
The F10 AS3D from projectiondesign packs full 3D stereoscopic capability at a 120Hz refresh rate into a very small chassis, making the single-chip DLP unit easily portable. At the German Aerospace Center, three of these are mounted vertically next to each other to provide a resolution of 2555x1400 pixels on a rear-projected flatscreen measuring 11.5'x6.5'. Generating up to 2000 lumens to produce a picture with 1920x1080 or 1400x1050 resolution, the projector can display either 16:9 or 4:3 aspect ratio images. The 220W UHP lamp is rated up to 3000 hours in normal brightness mode while the video inputs include two DVI-D, two VGA, one component, one S-Video, and one composite terminal. Control and communication options include USB, 9-pin serial, and an RJ-45 LAN connection.
Sanyo has another notable entry in the ultra-short-throw 3D category in the PDG-DWL2500, which can throw an 80in. diagonal image from a distance of about 13in. Using the frame sequential display format, the projector emits 2500 lumens in a 16:10 aspect ratio. The unit draws a total of 400W using a 275W NSHA lamp and provides a fixed focal length with manual focus. The range of video inputs includes 15-pin D-sub, S-Video, composite, and HDMI along with a PC monitor output connector. The projector is network controllable on an RJ-45 terminal and offers closed caption capability. The entire unit is easily portable at 13.7lbs.
