4 Ports 4K Multi Format Video Switch, combines the video Auto-switching with audio embedder, IR, and RS-232 serial/ GUI control function - VKSMC-421

VKSMC-421, Multi Format Video Switch, allows users to switch between 4 video sources (VGA, HDMIx2, DP) and then delivers the selected video stream to HDMI output. The “Auto-switching / input auto detecting” function always routes the last connecting stream (as first priority) to the output. Audio embedder function embeds audio from a 3.5-mm source to an HDMI signal. EDID Auto learning ensures that every video source is displayed at the optimal resolution and format without any compatibility issue.
