With a kiosk housing and capability for internal PC and network connections, the 70in. portrait screen D705SLI stands out in malls, airports, and other busy public places. Hyundai IT added an automatic cooling system, stereo speakers, and touchscreen for high interactivity and low maintenance. The monitor includes VGA, HDMI, composite, and component inputs along with automatic power control, tempered glass, and an optional anti-reflective coating. The CCFL backlit unit has a 178-degree horizontal and vertical viewing angle.
The Breeze Linux-based media player from Keywest Technology can be used as a low-cost hardware component in the company’s new scalable Breeze Digital Signage System, built to run on cloud-based networks. Capable of handling images, HD video, audio, web pages, and text, the player also supports layering as part of the overall system. Breeze Digital Signage has widgets that allow the addition of clocks, calendars, weather data, Twitter feeds, RSS feeds, streaming video, Facebook content, Sales Force CRM events, and QR codes to digital signage screens.
Designed by LG in the form factor of a slide-in card, the NA2100 media player fits into the port of a compatible LG LCD monitor to provide programmed playback through its HDMI video output. The included management software provides menus for control of networked displays and running video, stills, audio, and flash files. The panel has two USB 2.0 ports and a PCI Express card slot. Main memory is DDR3 SDRAM unbuffered 1066 1024MB SODIMM type with Windows 7 as the embedded OS.
When HD video signals must be sent long distances, Magenta Research has the ability to extend HD up to 500ft. with the HD-One DX500 and LX500 transmitter/receiver pairs. The DX500 handles uncompressed 1920x1200 video, HDCP, and embedded audio in Dolby TrueHD and DTS-HD Master Audio the full distance over UTP cable. The LX500 pair adds bidirectional RS-232 and IR over a single UTP cable, with two IR dongles included. The video connection is HDMI, while RS-232 is on 9-pin D-sub, and IR is on mini jacks.
The LM55S1 55in. full HD, direct-lit LED, super-narrow bezel LCD monitors from Mitsubishi combine a thin 5.3mm bezel with compatibility for Crestron RoomView and AMX Device Discovery along with an OPS slot to accommodate a PC or 3G-SDI video input. Up to four monitors can be daisy-chained through the DVI connections. On larger videowalls, tiling compatibility with frame compensation adjusts the image to compensate for the bezels. The unit also supports closed captioning and picture-in-picture.
For larger lobbies and retail areas, the NEC 80in. V801 LED edge-lit commercial display is hard to miss and its built-in OPS slot simplifies digital signage installations. The monitor can accept VGA, RGBHV, composite, S-Video, HDMI, DisplayPort, and DVI video, and pass on the DVI-D via loop-through. Audio connects on a mini jack for sound through the internal speakers, and there are external speaker terminals. Control can be connected with LAN or RS232 inputs and serial control can be looped through, as well.
New from Opticis, the compact optical DisplayPort extender, DPFX-100-TR enables transmission of 2560x1600 resolution video signals at 60Hz up to 985ft. over two LC connected fibers without any scaling or data compression. 10.8Gbps (2.7Gbps per lane) data throughput is provided, and it can be run on USB power through a DC adapter. The HDFX-150-TR, an optical HDMI extender, is compact with four LC fiber connections. The transmitter/receiver set enables a 1920x1200 or 1080p/60Hz signal to be sent up to 985ft. and supports 3D content with the same powering method as the DPFX-100-TR.
