The 52in. GM-F520S from JVC has an ultrathin 0.68in. (17mm) bezel for either single- or multimonitor videowall applications. Its built-in motion detector can sense movement at a distance up to 16.4ft. and remains activated until the motion stops. This feature can be used to turn the monitor on or off, control the volume level, select inputs, swap in main and subpicture, and control the backlight for power saving. The screen can be positioned horizontally or vertically, and its 700cd/m² brightness and 2000:1 contrast ratio work for outdoor display areas. Input formats include composite video on BNC with output, RGB in and out, and DVI input. External control connections for RS-232, RS-485, and LAN are included.
With an ultraslim .676in. (16.9mm) bezel for videowall applications and the ability to divide its own screen into a 5x5 videoscreen display using Split Zoom, the M4224C-BA from LG Electronics offers both LAN and RS-232 remote control. Via the serial connection, the monitor can be powered on and off, its color calibrated, the aspect ratio changed, and many other adjustments can be done, and over a LAN, both content and multiple-monitor control can be distributed. Video sources include composite, component, S-Video, RGB, and HDMI with line audio and loudspeaker outputs. The unit uses 200W of power, making it Energy Star 5-compliant.
For command and control, digital signage, and other such applications, Mitsubishi offers the MDT521S 52in. LCD monitor with 1920x1080 resolution, 700cd/m² brightness, 178-degree horizontal and vertical viewing angles, and up to 50,000 hours backlight life. Video-signal inputs include DVI-D, VGA, and HDMI. The monitor also features a built-in Cat-5 receiver for video and control signals on one cable. An RS-232 loop-through allows control signals to daisy-chain between multiple monitors. The unit weighs 88lbs. and has VESA-standard mounting points and external loudspeaker terminals along with dual ambient light sensors to allow the monitor to automatically adjust its brightness to suit the environmental light level.
The P521 from NEC is a 52in. monitor designed with the Digital Signage Technology Suite, a set of more than 30 features applicable to digital signage applications. The monitor has a native 1920x1080 resolution with a 2000:1 contrast ratio. Daisy-chain controllability for multiple monitor setups, TileMatrix for creating videowalls, and a realtime clock and scheduler. CableComp+ automatically compensates for cable length with a digitized signal-delay circuit. The unit also provides Ethernet connectivity for the same control as with the serial connection plus automatic email notification for diagnostics. The P521 is designed and built for long-uptime applications.
Networkable customization is carried to the maximum with a variety of optional slot-in boards on the new Panasonic TH-103PF12U 102.5in. high-definition plasma display. With built-in videowall image enlarger, dual-picture mode, serial control, and a power-saving features, the monitor is intended for signage and other public display applications either alone or in a monitor-wall group. A contrast ratio of 40,000:1 rates the display ready for brightly lit public areas, and the unit is equipped with audio output on RCA jacks. LAN control is also available with an option board, and the monitor weighs 443lbs.
The BDL5231V 52in.-diagonal LCD multi¬media monitor from Philips has a full 1080p capability with enhanced zoom for tiled-matrix applications up to a 25-monitor wall and a slim, 1.04in. bezel. In the back cover is the Smart insert that will fit many small-form-factor PCs for self-contained public signage. Advanced remote control and adjustments may be made through the RS-232 port including serial number lookup and backlight remaining lifetime, along with cooling and wattage control to lower reduce power consumption by up to 50 percent and extend the product’s lifespan. The unit features a brightness of 700cd/m² and contrast ratio of 4000:1.
