Control video and audio routing across two HDMI displays without moving cables or reconfiguring sources. The Black Box VSW-HDMI4X2-4K is a 4 x 2 matrix switch designed for professional AV environments that need flexible source selection and consistent 4K output. Each of the four HDMI inputs can be routed to either output, allowing one source to feed both displays or different sources to appear on each screen. That makes it a strong fit for conference rooms, training spaces, and monitoring setups where presentation flow changes often and uptime matters. By centralizing routing in the switch, teams reduce wear on ports and avoid the operational friction of manual cable swaps. The rack-mountable form factor supports clean integration into AV cabinets and equipment racks. With HDMI input and output support, wired connectivity, and 4K graphics mode capability, this matrix switch is built for installations that need dependable signal control at the edge of the display chain. A 3-year limited warranty adds confidence for deployments where the switch becomes part of the daily workflow.
