HDTV Supply's WolfPack Quad Video Wall supports simultaneous viewing of four separate high definition input sources on one screen and it has three different multi-view modes. The Quad Video Wall is also a very fast seamless four-input HDMI switcher. The WolfPack Quad Video Wall seamless switching feature eliminates virtually all of the switching delay, commonly found in most switchers. A front panel button allows you to instantly switch between the normal matrix mode and the quad video wall mode.
