The latest round of display monitors for commercial operation have followed the trend toward networkable connectivity in all AV devices with RS-232 and LAN management. Digital signage applications especially benefit from the combination of automatic responses to ambient light levels, custom software applications for remote control, and more durable hardware for outdoor and other challenging environments. The models shown here are typical of the march toward networked display systems and automatic environmental adjustment mechanisms used on commercial display units in public areas. Most of these also represent the new power-efficiency efforts of manufacturers in recognition of the latest green AV developments in the industry.
The ALM series monitors from Akira are designed either for single-display applications or to form monitor walls. With its 1.36in. (34mm) bezel, the 82in. ALM8201 is typical of the line. The monitor provides a brightness of 600cd/m², a native screen resolution of 1920x1080, a 1200:1 contrast ratio, and a viewing angle of 178 degrees. Along with its PC input, the unit also accepts composite, component, and HDMI/DVI, and it has outputs for each of these video formats. The monitor can be controlled on an RS-232 connection, and Akira provides software for handling monitor-wall setups. The design is suited for long-duty-cycle applications with a mean time between failure specification of 50,000 hours and power consumption figure of 1100W maximum.
With HD/SD-SDI digital inputs, DVI, S-Video, composite, component, and VGA, the Boland Communications DHD55Wa is a 55in.-diagonal monitor with a 1400:1 contrast ratio, 10-bit digital processing, 178-degree viewing angle, and 1920x1080 screen resolution. The image can be adjusted with presets for adjustable aspect ratio. The unit has picture-in-picture, splitscreen, and remote control by infrared and RS-232 with optional LAN connectivity. A video source may be placed side by side with an HD or PC image, with the window size and position adjustable. The color-matched fluorescent backlight has a 50,000-plus-hour lifetime, and the monitor uses 345W on AC power, 300W on DC. The rear of the chassis includes 100 and 200 VESA bolt patterns for standard mounting.
The 42in. LD4200 widescreen LCD display from HP has an active-matrix, thin-film-transistor panel and is intended for long-duty-cycle operation in public display areas such as airports, retail stores, and restaurants. It has a contrast ratio of 1000:1 and screen brightness of 500cd/m². Mounted in landscape or portrait position, the monitor offers picture-mode and tile-mode control with HDMI, composite, and S-Video inputs. For signage applications, it includes remote control through an RS-232 port. Options include a thin client mounting adapter plate and mounting loudspeakers. The unit has a VESA-compliant 600x400 hole-mounting pattern and weighs in at 46.7lbs. without stand and loudspeaker.
The Hyundai D467ML 46in. LCD display is designed for out-of-home advertising applications. It has a resolution of 1920x1080, a brightness of 700cd/m², and a contrast ratio of 4000:1. The screen has a horizontal and vertical viewing angle of 178 degrees and an average lifetime of 50,000 hours. The input formats include VGA on a 15-pin D-sub, HDMI, composite, and component on BNCs and a 9-pin D-sub RS-232 port through which remote setup can be done. The remote setup can include a monitor wall position assignment which can also be done through an onscreen menu. The ultranarrow-bezel design permits a very close spacing of screens in a monitor-wall setup. For daisy-chaining video signals, there are VGA, HDMI, composite, and component video outputs as well as the RS-232 loop-through. The unit weighs in at about 70lbs. and uses 260W of power. It is loudspeaker-ready and has a VESA mounting-hole pattern of 600mmx200mm.
Another entry in the 46in. screen size is the HLM-4600W TFT LCD display from Ikegami. It has a brightness of 450cd/m², a 176x176-degree viewing angle, native 1920x1080 resolution, and 266W power consumption, and the monitor drops to 3.5W in standby mode. The sturdy unit has carrying handles and no raised front-panel connectors or controls to break off. The 1700:1 contrast ratio and 6-millisecond response time make clear pictures from the HDCP-compatible DVD-D, analog RGB, composite, and component video-input signals. Remote setup and status monitoring may be done through RS-232, and there is a loop-through for this port as well as the DVI-D for daisy-chaining up to five monitors.
