Today's business projectors squeeze clever features into smaller packages.
Designed for widescreen-format laptops and imaging applications that use 16:10 aspect ratios, the Hitachi CPX3 3LCD projector offers 1280x800 WXGA resolution. The 2000-lumen, 3.9lb. CPX3 also offers a wide-angle lens, which allows the projector to be used close to the screen with no obstructions. The CPX3 features a new remote control with My Source and volume functions. The CPX3 also offers closed captioning and input naming, which lets users customize the names of the projector's input sources. In the same line, Hitachi's CPX4 3LCD projector comes with Wi-Fi connectivity.
For greater brightness, Hitachi's CP-WX410 3LCD projector presents widescreen capability and full connectivity. The CP-WX410 offers a 16:10 aspect ratio, 3000 lumens brightness, and optical zoom. The CP-WX410 also features a side-mounted hybrid filter that provides extended filter life thanks to a 2000-hour filter-cleaning cycle.
The InFocus IN3108 widescreen DLP projector boasts 3500 lumens and a 2000:1 contrast ratio and features a built-in InFocus Dynamic Messaging System (DMS), which allows for instant onscreen display of messages. This WXGA native (1280x800) projector also comes equipped with the InFocus LiteSwitch instant on/off feature—which, along with DisplayLink content-over-USB connectivity, allows fast and easy setup. The InFocus IN3108 also offers a nifty LiteTouch control panel, which stealthily disappears under a sleek high-gloss finish when the projector is not in use, and assignable audio that lets the presenter sync any audio source with a selectable video input except, of course, those coming in over HDMI. Combined with HDMI, VGA, composite video inputs, and a wireless-ready port for LiteShow II Wireless, the IN3108 will project from any video source or wireless computer.
Known for its higher-resolution, higher-contrast projectors, JVC has released its new 10-megapixel 4K/2K Direct-drive Image Light Amplifier (D-ILA) projector, the DLA-SH4K, which provides four times the resolution of full HD. The projector's chassis achieves a 65 percent reduction in size compared with conventional projectors in its class thanks in part to JVC's latest 1.27in. D-ILA devices and a new optical system that features an 825W xenon lamp to generate a light output of 3500 lumens. Two DLA-SH4Ks can be stacked for increased light output, and the projector can be inclined up to a ±90-degree tilt angle and has a horizontal lens shift of ±25 percent and vertical shift of ±50 percent, which enables flexible installation. The DLA-SH4K includes dual-link DVI-D input terminals that accept a wide variety of input resolutions in addition to the RS-232C and USB connections and an Ethernet interface that enables installation and adjustment from web browsers.
Mitsubishi has recently released two new high-brightness installation DLP projectors, the XD3200U XGA (1024x768) and the widescreen WD3300U WXGA (1280x800), each with a new virtually sealed color wheel that helps prevent dust accumulation. This new color wheel design, along with an improved cooling-duct path, allows both the WD3300U and XD3200U to operate at a low 26dBA noise level (Low mode). In addition, both models include a new lamp-drive system that reduces the overall deterioration rate of the lamp, resulting in an estimated lamp life of up to 4000 hours in Low mode. Starting with these two models, Mitsubishi is greening its projectors with energy-efficient, long-life lamps; lead-free solder on all printed circuit boards; digital user manuals; and use of recycled paper in printed materials and packaging.
Silicon Optix HQV technology produces improved video processing in the NEC WXGA (1280x800) NP3151W projector, which features a 4000-lumen output and a remote desktop connection that allows the projector to connect to a networked computer. The NP3151W can provide up to 3000 hours of lamp life in Eco mode. The NEC NP600 is a value-driven projector with dual computer inputs, including DVI-I, which makes it easy to quickly switch between presenters. It even has a Virtual Remote (DDC/CI) to control the projector over the VGA cable directly from a computer without the need for additional control cables.
