group of smaller displays tiled together in a matrix to create one large display. iView Data provides the controller box
that drives the display over multi-screens. All the video wall controllers support different configurations of the
video output signals. The videowall control (OSD) buttons are located on the front panel of the video wall controller
for easy access, while all the video and power cables are connected to the rear panel for
convenient cabling. The video controllers can be connected to LCD or DLP panels, video wall cubes, projectors or
any monitor that accepts a DVI input signal.
