The new model is joinning the DLA-SH4K, which debuted in January 2008. Like its predecessor, the DLA-SH7NL achieves an ultra-high resolution of approximately 10 megapixels (4,096x2,400), or more than four times full HD, plus a 10,000:1 native contrast ratio.
Notable features of the new DLA-SH7NL include the following Dual 330W ultra-high-pressure mercury lamps, producing 5,000 lumens of brightness. In single lamp mode, the DLA-SH7NL can automatically choose the lamp with less cumulative operating time for maintenance efficiency. This, plus the addition of a low-power mode, enable lamp life of approximately 3,000 hours, about double that of conventional projectors.
JVC's own 4K2K D-ILA devices deliver approximately 10 megapixels of high-resolution, and can simultaneously display two or four screens in WUXGA (1,920 x 1,200) and full-HD resolution. Multi-screen projection is facilitated by four DVI (Dual-Link) input terminals supporting an array of PC input formats.
The device Weighs about 50 kg, excluding lens. Elaborate design offers operational flexibility, including stacking two projectors to display 3D images or installation on a 90-degree tilt.
The DLA-SH7NL operates on normal AC 100-220V power and consumes less than 1.1kW,. Color registration of RGB panels in the optical system can be mechanically adjusted in 1/10 pixel accuracy. Six test patterns, including a crosshatch and color bars, enable image adjustment without external signal sources. Three types of gamma tables are incorporated to set tone expression in accordance with specific images.
The Ethernet-compatible DLA-SH7NL can be configured via a PC web browser. Multiple projectors are networkable for operation via a single PC. E-mails can be generated automatically to send lamp-replacement reminders and error-status notifications for enhanced maintenance. The projector's configuration data can be stored in a USB memory device.
