The UD8400U widescreen projector from Mitsubishi uses a dual-lamp design to apply 6500 lumens to the screen at 1920x1200 resolution. It automatically corrects for color, sharpness, curved projection surfaces, and multiple screens. The unit accepts input in component, S-Video, DVI-D, composite, and HDMI along with its ability to connect HD/SD-SDI sources. Multiple units can be combined with its native edge-blending capability and its swappable six-segment color wheel can help closely match colors between multiple images. The UD8400U can accept a variety of lenses and its rotating self-cleaning air filter automatically reminds users when to remove and rinse it. A maintenance-free heat pipe system is used for cooling.
For digital cinema applications, the 33,000 lumens NC3240S 3D DLP projector is designed by NEC for use on screens up to 105ft. Eight different configurations can be button-selected with aspect ratio, lens shift position, and zoom and focus among the storable parameters. Automatic lamp brightness control adjusts the power as the lamp ages. External control is provided through a LAN port, RS-232, USB, GPIO, and a remote control connector. Video signal inputs include HD-SDI and DVI-D. The focus, zoom, lens shift, and light shutter are motorized. The unit is both liquid and air-cooled. It can be used with a variety of interchangeable lenses, and it ships with a lens holder to attach to the primary lens.
Using a single lamp to deliver 6000 lumens, the Optoma TW865-NL has a sealed light engine and a center mount lens for ease of installation and provides 1280x800 native resolution. The model has a side-loading lamp, mechanical shutter, self-cleaning filter, 120Hz 3D projection capability, Crestron RoomView for remote management, and PJ Link for LAN support. Input formats include HDMI, DVI, VGA I/O, S-Video, composite, component, and RGBHV on BNC connectors. USB connections are available for signal input and control. Remote monitoring and operation are done via RS-232 and LAN ports. Audio inputs can drive an internal 5W speaker, and there is a stereo mini audio output connector as well.
The PT-D12000 3-chip DLP projector from Panasonic uses a four-lamp optical system delivering 12,000 lumens with all of the lamps in operation and can be used in lamp relay mode to maintain steady operation for up to 24 continuous hours. Among the input formats are D-sub 15-pin, DVI-D, S-Video, composite, and component. With the addition of an ET-MD100SD4 expansion board, the projector supports HD-SDI signals. Other features include 3D color management, 10-bit color processing, a liquid cooling system, and an auto-cleaning robot that uses a brush to clear away dust adhering to the filter. The auto cleaning process can be controlled manually or scheduled.
