The Video Wall System

The LAN based controllers offer coherent multi-screen graphics surface combined with live video or RGB input source visualization over the wall of multiple projectors. The graphics system is Microsoft Windows or Linux X Window compatible. The live video windows display full motion video from multiple PAL or NTSC sources while the real time RGB windows visualize graphics information of RGB or DVI inputs. Advanced wall management and easy-to-use remote control tools handle graphics, video and RGB/DVI windows that can be opened, moved and zoomed over the multi-screen wall area freely.

Wall Management

The DXWall management software offers tools for any job of a complex video wall system. All the activities and controls are managed by easy-to-use graphics user interfaces. The local operators of the wall can use English, Chinese, Japanese, or Korean user interface.

The client-server based DXWall software system offers different modules for operator administration, remote wall control, input source display, layout definition, scenario handling, on-screen-display handling, and touch panel interfacing.

Typical applications can be summarized as follows:

DEXON’s DXN-2200 controllers are multi-screen graphics servers working on Microsoft Windows XP/Vista/7 platforms and networks. The DXN-2000 video wall servers drive multiple screens to form one large video wall. The wall displays Microsoft Windows graphics
desktop and overlay windows of multiformat inputs displaying DVI, RGB, component video, S-video or composite video input signals in real time. DXN-2000 controller family applies advanced Express
Crossbar technology for the full digital display of digital and analogue input information. Graphics, live video and DVI/RGB windows can cover multiple screens as the windows can cross the borders of monitors. Highly optimized graphics functions, quick window positioning, unlimited zooming, automatic cursor and input handling
give unprecedented freedom to control the wall area.
