Technology Showcase: Corporate Projectors
Apr 13, 2009 12:00 PM, By Jay Ankeney
Today's business projectors squeeze clever features into smaller packages.
Like the NP3151W, NEC's value-driven NP600 provides up to 4000 hours of lamp life in Eco mode, where it puts out 70 percent of its normal 3500 lumens, and its complete line of optional bayonet lenses allows for quick and easy lens changes. Both NEC projectors boast an auto power-on feature, which means connecting a laptop's VGA cable turns them on. Used in combination with the Virtual Remote feature, you can still use the projector if the dedicated remote is missing from the conference room.
Entering into the short-throw projector arena, Optoma Technology has released its EX525ST, which can present a high-resolution image as large as 100in. diagonal from as close as 4ft. from the wall. The optical system incorporates an aspherical lens element that can provide a throw ratio of 0.6:1. The EX525ST features the latest Texas Instruments DLP chipset and uses Optoma's BrilliantColor technology, letting its 200W lamp provide an output of 2500 lumens and a contrast ratio of 2500:1. Optoma's EX525ST also boasts extensive connectivity options such as DVI, VGA, S-Video, composite, RS-232, USB, and RJ-45. It can be installed by itself or used with interactive whiteboard technology.
Panasonic is proud that its PT-F300 series projectors' optical blocks maintain a high level of performance over time because of the use of inorganic materials in the LCD panels and polarizers. The PT-F300 series features Panasonic's Daylight View 5 technology, and a high-performance optical system is combined with a high-efficiency 250W UHM lamp to deliver a high brightness of 4000 lumens (PT-F300NT and PT-F300) or 3500 lumens (PT-FW300NT and PT-FW300). Panasonic's original Multi Projector Monitoring and Control freeware allows the user to control and monitor up to 1,024 projectors via LAN from a remote location.
Available for the first time just this month is Panasonic's new projector lineup featuring the PT-DZ6710/DZ6700 with WUXGA resolution for widescreen images, the PT-DW6300S with WXGA resolution, and the PT-D6000S with a peak brightness of 6500 lumens. They all come with unique features such as such as the RGB booster, which provides vivid color reproduction and high brightness, and the auto cleaning filter, which eliminates the need for filter maintenance for a full 10,000 hours.
Although not providing as bright an illumination output as most corporate boardroom projectors, the LED light source in the new Plus Vision PL-105S Taxan projector means the lamp never needs to be replaced. Its 20,000-hour light-source life is the equivalent of seven to 10 normal lamps. DLP technology in the PL-105S provides a crisp image with a 1400:1 contrast ratio, and its optional high-gain screen effectively brings the brightness of the PL-105S up to 400 lumens. In addition to the computer and audio inputs, a USB port has been provided for playback of moving images, static images, and sound without a desktop or laptop.
The high-end F32 series from projectiondesign is intended for graphically demanding visualization applications where image quality and reliability are key requirements. The F32 series features WUXGA, 1080p, or SXGA+ resolution options with unique color-matching and calibration tools in RealColor with intelligently adaptive and active cooling of the entire system. The F32 series is also available in special versions for 3D stereo display by using Infitec Wavelength Multiplex Imaging, which lets a set of two projectors show passive 3D stereo for small or large groups. A significant benefit of using F32s with Infitec stereo technology is that the filters can be deactivated by remote control so that switching from 3D to 2D in the middle of a presentation is easy.
The new Sanyo 3LCD PLC-XTC50L has the benefit of being able to automatically switch between two lamps to prevent the interruption of the projector's use in extended use. This dual-lamp system provides up to 6000 hours of use, and Sanyo's exclusive PJ-Net manages a lamp-switch timer to change lamps every 24 hours for 24/7 applications. To further provide high reliability and easy maintenance, the PLC-XTC50L is equipped with Sanyo's exclusive Active Maintenance Filter (AMF), which detects air blocks or clogs and then scrolls to the next clean filter. Vertical/horizontal lens shifting and keystone correction allow the PLC-XTC50L to be used in nearly any location. With 5000 lumens and an 1100:1 contrast ratio, the PLC-XTC50L offers a wide selection of connections including DVI-D with HDCP; D-Sub 15-pin; BNC 5-pin type (Y, Pb, Pr, or RGB); composite (RCA); and S-Video mini-DIN 9-pin.
Sharp has targeted its PG-D3750W DLP projector directly at the corporate installation market with its WXGA (1280x800) native resolution and 3700 lumens. In addition to a wide complement of inputs and outputs—HDMI, DVI-I, RGB/component, S-Video, composite video, stereo audio, and outputs for stereo variable audio and RGB loop-through—the DLP light source is in a sealed system with a filter-free design. Sharp's PG-D3750W comes with anti-theft features including a LAN monitoring function, reinforced-metal security bar, metal security plate (for use with ceiling bracket), and optional heavy-duty security-cable kits to be used with Sharp ceiling brackets.
