At the top of Samsung's EX-Series, the 55in. 550EXn touts a mercury- and halogen-free design with an LED backlit screen and 120Hz scanning for smooth motion graphics in digital signage applications. Among the video signal interfaces included is a DVI output for easy distribution of high-def video among units in a videowall. Control is done through RS-232 serial and LAN connections. It also features an integrated PC and web-based server software. The screen features 450 cd/m² brightness, 6000:1 contrast ratio, 1920x1080 resolution, and a 6-millisecond response time. Audio connections include a stereo mini jack, dual 5W outputs, and well-hidden built-in speakers. The unit's typical 200W power consumption drops to less than 3W in standby mode, and the chassis weighs in at 46.3lbs.
For high-uptime display duty in either landscape or portrait orientation, Sanyo offers the PID-42AE1 42in. LCD panel with a 1000:1 contrast ratio, 500 cd/m² brightness, 9-millisecond response time, 1920x1080 resolution, and a wide range of computer resolution compatibility. In addition, the unit accepts video in composite, component, RGBHV, and DVI-D with HDCP along with audio on RCA and stereo mini jacks. Audio line output RCA connectors and 6W external speaker connections are included, and control is done through RS-232 input and loop-through for multi-unit display arrangements, which may be expanded with the monitor's picture-in-picture and picture-by-picture features. Power consumption is 210W, which drops to .8W in standby, and the weight is 40.57lbs.
Special digital signage features top the specs list for the Sharp PN-E521 52in. professional monitor with fanless design for quiet operation, zoom display mode, and Sharp Digital Signage Software (SDSS) compatibility. The thin bezel allows the screens to be stacked in a videowall up to 5x5, and the optional digital signage controller PC can attach directly to the back of the chassis. Certified for continuous 24/7 operation, the unit has a display resolution of 1920x1080, 500 cd/m² brightness, and can be oriented in landscape or portrait mode. HDMI, D-sub, and 15-pin are standard video inputs while the optional PN-ZB01 interface board adds DVI-D in/out, RGB analog input on BNC connectors, component, S-Video, and composite video. Stereo sound in and out connections are also standard. Serial control may be used with 9-pin D-sub ins and outs and optional LAN connection.
The new FWD-S42E1 42in. LCD monitor from Sony offers 700 cd/m² brightness, 1920x1080 resolution, 1000:1 contrast ratio, and an 8-millisecond response time to suit a range of installations. Video interfaces include HD 15-pin, S-Video, composite, and DVI, and control is connected through RS-232 in and out ports along with Control S out and optional RJ-45 network port (standard on the FWD-S47H1 and FWD-S42H1). Audio inputs for the video connections are on stereo mini jacks. Left/right 7W external speaker outputs use grip connectors. The unit runs on 160W maximum, and power consumption drops to 98W in Eco (low brightness) mode and .5W in standby. For its size, the monitor is fairly light at 66lbs.
Seven-day on/off scheduling, screen saver image sticking protection, and remote/panel control lockout top the list of public display features on the Viewsonic CD5233 LCD monitor. Designed for high-uptime applications, the unit includes both internal dual 5W speakers and external speaker terminals for 7W output. With a 4000:1 contrast ratio, an 8-millisecond response time, and 700 cd/m² brightness, the unit can be used in high ambient light locations, and the RS-232 serial control input and output connectors suit videowall installation. Video inputs include HDMI, DVI, component, and VGA while there are VGA, component, and DVI outputs. The monitor runs on 360W power and weighs 83.8lbs without stand.
