Gefen EXT-HD-VWC-144: Videowall controller in 2×2 by HDMI for digital signage applications

The videowall controller that Gefen has developed is a robust and cost-effective solution for feeding HD content through HDMI. An ideal equipment for digital signage applications in commercial environments, Entertainment & Corporate, as well as control rooms.

With the EXT-HD-VWC-144, Gefen has developed an ideal solution for digital signage applications in stores, Entertainment Centers, lobbies of buildings or companies, as well as for visualization in control rooms. It is a videowall controller designed for the supply of content in high definition in compositions of 2×2 via HDMI (HDCP protected). HDMI outputs are freely scalable to suit different types of content playback devices.

HDTV screens are installed in a configuration of 2×2 To create a large videowall. Accepts a single HDCP-compliant HDMI source and splits the image across four equally sized displays, each with up to 1080p Full HD resolution. Its versatile bezel compensation capability allows it to adapt to any format.

Power-on functions, the lock buttons and control menu are accessible via the front panel or from the IR remote control, as well as via RS-232 and IP (Web Server Interface, Telnet and UDP). Intuitive graphical user interface simplifies commissioning and configuration. HDMI inputs identify a high-definition signal with a resolution up to 1920×1200 (WUXGA) and 1080p (Deep Color). On the output side of an image can be scaled from 480p to WUXGA.

An essential feature that should be highlighted is the proper representation of the high-definition video displayed on the screen by so-called web compensation.. This is done depending on the type of display used in the installation. This Gefen videowall controller allows the pixels to be perfectly adjusted and compensated in length and width. In addition, Gefen offers the ability to independently figure each output in terms of video quality, brightness, contrast, colour, Saturation and color temperature since each monitor does it differently.
