The latest LCD options incorporate robust and interactive feature sets.
Sony’s two newest LCD full HD (1080p) displays are the 42in. FWD-S42H1 and 47in. FWD-S47H1, designed for commercial installations. For lobby signage applications, each has a higher brightness than previous versions, typically 700cd/m2 at 1000:1 contrast ratio, with a brightness boost setting for even brighter images, and the displays are specially designed to accommodate Sony’s HD player, model VSP-NS7. Users can remotely control and manage the displays from a central location, with firmware upgrades available over a local area network. Three types of screensavers are available: standby, which is activated while the backlight is off; all-white; and sweep. They automatically detect use in landscape or portrait mode, and illuminate a logo in the appropriate orientation. Invisible loudspeakers, rear control buttons, and a slim bezel design allow the displays to easily blend into the décor of any setting.
The new ClearScan 240 technology in Toshiba’s Regza ZV650 LCD display combines 120 frames per second with advanced Backlight Scanning Technology to create a 240Hz effect. This new system also helps the ZV650 series attain its high 100,000:1 dynamic contrast ratio, combining amazing picture clarity and enhanced picture depth. To make connecting source devices simple and flexible, Toshiba’s ZV650 incorporates an expanded array of connectivity features including a USB port for playback of digital video, audio and picture files, an SD card slot for playback of digital picture files by simply taking the SD card from the camera and inserting it into the TV, four HDMI inputs with InstaPort for faster switching, and Regza-Link for two-way device control. The ZV650 series also features an IR pass-through port to control source devices that may be hidden in a cabinet or closet, and a high-resolution PC input that allows you to use the TV as a big-screen PC monitor for multimedia or gaming.
ViewSonic’s 42in. CD4230 LCD display that is appropriate for lobby installation features a 14mm bezel, 500cd/m2 brightness at a 2500:1 contrast ratio, and a fast 8 millisecond response time that delivers blur-free scrolling text or video. It also has HDMI and VGA inputs, and the DVI and RS-232 inputs/outputs on the CD4230 allow you to daisy-chain multiple displays into your network and still control each display individually. For many customers, ViewSonic has found the TV equivalent of the CD4230, the N4285p, can be a cost-efficient alternative so ViewSonic gives it a one-year warranty just like the commercial model. The N4285p has 500-nits brightness, a contrast ratio of 2000:1, and plug-and-play connectivity of two HDMI inputs for HD set-top boxes, standard and HD DVDs, game consoles, Blu-ray Discsall accompanied by 20W Dolby Digital stereo sound.
The 42in. D42FMP1 LCD display monitor from Westinghouse Digital Electronics showcases images and content in landscape and portrait modes and features Westinghouse Digital’s 1080Pure for 1080p resolution out of all HD connectors. Its DayBright technology allows for high-contrast viewing both during the day and night, and the D42FMP1 provides a multitude of input connectors including RS-232 in and out, DVI and VGA, S-Video, component, and composite. Westinghouse Digital’s D42FMP1 LCD display monitor’s component inputs can easily be daisy-chained with other displays via specially-designed cables that eliminate the need for splitters or the unsightly long cables usually needed to hook up DVD players or related devices, and its RS-232 inputs can also be daisy-chained to other displays so that multiple units can be controlled from one PC source.
