The Monoprice Blackbird™ 4x4 HDMI® Seamless Switching Matrix is an easy to use solution for distributing any of four connected HDMI sources to any of four HDMI displays, in any combination. It supports video resolutions to 1080p@60Hz and includes support for PC control via the RS232 port. The seamless switching feature eliminates virtually all of the switching delay, commonly found in most switch and matrix devices. A front panel button allows you to instantly switch between normal matrix mode and the video wall mode, which splits a single source into four parts for distribution to a 2x2 array of HDMI displays to create a single larger image.
