ATEN VM8824 4-Port True 4K HDMI Output Board with Scaler for VM3250

"4K" on a spec sheet means a lot of things. The VM8824 is the one that actually pushes 4096 x 2160 at 60 Hz in full 4:4:4 colour — no chroma subsampling, no bandwidth compromise. It drops into the VM3250 chassis and gives you four HDMI outputs with a True 4K scaler on each port. HDCP 2.2 means your protected content plays without handshake drama. Seamless Switch keeps the feed live during transitions. EDID Expert picks the right resolution per display so your wall doesn't flicker on power-up. Audio extraction on four dedicated connectors. Five-metre max cable run — plan your rack-to-display distance around that
