Key Digital just debuted something called the KD-MLV4x2. It’s basically a four-input, two-output video matrix where all four images can be displayed simultaneously or one at a time. It supports input resolutions up to 1920×1200 on HDMI or VGA, and audio-follow video and can combine them to output 4K (3840×2160).
This is an inexpensive way for installers to give any large panel or screen video-wall-like functionality. In full screen mode the screen will display any of the eight (four HDMI and four VGA) video sources, in quadrant mode this view is all four video sources in equally sized-quadrants, and in multiview mode the option is to choose a primary video source on the top, bottom, left, or right of the screen while still viewing the additional three sources. In addition to multiview picture-in-picture functionality, KD-MLV4x2 is Key Digital’s first ever seamless switcher.
The KD-MLV4x2 can be controlled by IR, RS232, IP or open API, in addition to Key Digital’s control system Compass Control Pro.
