Quad Monitor KVM for Four Computers

The AUTYUE KC-404DH connects four computers to four monitors using one HDMI and three DisplayPort outputs per system. A single keyboard and mouse set controls all four PCs through the integrated USB 3.0 hub. The unit supports extended desktop or mirrored display modes for multi-monitor workflows.

Video Bandwidth and Cable Limits

Maximum supported resolution reaches 8K at 30 Hz or 4K at 120 Hz when using certified 8K-rated HDMI and DisplayPort cables. Shorter cable runs are recommended to maintain signal stability across all four video channels. The switch does not support EDID emulation, so display handshake depends on direct monitor connection.

Graphics Card and Power Requirements

Each connected computer must provide a dedicated graphics card with three DisplayPort outputs and one HDMI output to drive the quad-monitor layout. The host system must also support four simultaneous displays. A 12 V DC power adapter is required for operation and is included in the package.
