KVM Switch ATEN CS1944DPA 4-port Dual-Display DisplayPort USB 3.0 8K

ATEN CS1944DPA is a 4-port KVM switch built for dual‑display DisplayPort environments. It enables one keyboard, mouse and dual monitors to control up to four computers, while providing USB 3.0 peripheral sharing and support for high-resolution video up to 8K. The unit is intended for multi‑system workstations in offices, creative studios, control rooms and testing environments where space efficiency and fast switching between hosts are required.

Advantages

The CS1944DPA supports dual-display DisplayPort connections and 8K video throughput, allowing clear, high-resolution output on two monitors simultaneously. Integrated USB 3.0 ports provide fast peripheral access and data transfer rates for external drives, webcams and other devices without the need to reconnect hardware when switching hosts. The switch offers simple host selection and consistent signal handling across all connected systems, reducing cable clutter and improving workflow efficiency.

Suitable for

• Multimedia editing workstations requiring dual-monitor, high-resolution output
• Offices and shared desks managing multiple PCs from a single console
• Control rooms and monitoring stations with simultaneous display requirements
• Test labs and development environments needing rapid host switching

Key specifications

• Number of ports: 4 computer ports supporting dual DisplayPort outputs
• Video interface: DisplayPort for each display channel
• Maximum resolution support: up to 8K (dependent on cable and host GPU capabilities)
• USB: USB 3.0 host/peripheral ports for shared keyboard, mouse and USB devices
• Console configuration: single keyboard and mouse with dual-monitor support
• Form factor: desktop KVM switch designed for rack or desktop placement

How to use

Connect two DisplayPort cables from each computer to the corresponding dual-display input ports on the KVM switch, and plug the console monitors into the dual DisplayPort console outputs. Attach the keyboard, mouse and USB devices to the USB 3.0 console ports. Power on the KVM switch and then the connected computers. Use the front-panel controls, hotkeys or on-screen display (if available) to switch control between computers. Ensure host video outputs and display settings match the monitors' supported resolutions to achieve optimal 8K or high-resolution performance.

Usage recommendations

For reliable 8K performance, use certified high-bandwidth DisplayPort cables and verify that each connected computer’s GPU and operating system support the target resolution and refresh rate. Place the switch in a well-ventilated location and keep firmware updated according to the manufacturer’s guidance to maintain compatibility and stability.
