You need four displays running 4K off one matrix switch, and you don't want to babysit EDID handshakes every time someone plugs in a new laptop. The VM8814 slots into the VM1600A or VM3200 and gives you four HDMI outputs with a built-in 4K scaler on each. Seamless Switch keeps the picture moving even mid-switch. EDID Expert sorts the resolution negotiation so displays power up at the right spec, first try. Pull stereo audio out of any HDMI source on dedicated connectors. Build video wall layouts through the web GUI when the room demands it. Hot-swap the board without powering down the whole chassis
