Four-computer dual-monitor KVM

This SMA KVM switch lets four PCs or laptops share one keyboard, one mouse and up to two monitors. It accepts both HDMI and DisplayPort inputs on each computer port and provides two monitor outputs that support 4K at 60 Hz as well as 1080p and lower resolutions. Three USB 3.0 ports add shared peripheral connectivity for printers, scanners or storage devices.

Rear-facing ports and wired remote

All video, USB and audio connectors are located on the back of the unit so cables stay hidden and the desk remains tidy. A wired push-button remote is included for switching computers without reaching the main box, while front-panel LEDs show the active port. The package supplies four USB 3.0 cables, a 12 V power adapter and a user manual for immediate setup.

Passive cooling with external power

The switch draws power from the included 12 V adapter and operates without internal fans, so it adds no audible noise to the workspace. USB 3.0 ports deliver up to 5 Gbps data throughput for connected peripherals. Video bandwidth reaches 18 Gbps per DisplayPort 1.2 channel, supporting extended, mirrored or spliced dual-monitor modes depending on the host graphics card.

Questions about this item

What resolution does the DP 1.2 interface actually cap at on this KVM?

The DP 1.2 interface supports up to 4K at 60 Hz, with a transfer rate of 18 Gbps, and is downward compatible with 1080p at 60 Hz.

How much desk space do the 9.06 x 6.77 inch dimensions need?

The unit measures 9.06 by 6.77 inches and stands 2.24 inches high, so allow roughly that footprint plus cable bend radius behind it.

Which cables go in first so the front buttons and remote both work?

Connect the 12 V power adapter first, then plug each computer's DP or HDMI and USB 3.0 cables into the rear ports, attach monitors to the two outputs, and finally link keyboard, mouse and USB peripherals to the front USB 3.0 ports.
