Dual-computer KVM for two monitors

This SMA KVM switch lets one keyboard, one mouse and two monitors control two separate computers. Each computer connects through HDMI 2.1, DisplayPort 1.4 and USB 3.0 cables, and the unit provides four downstream USB 3.0 ports for shared peripherals. The package includes two 1.5 m USB 3.0 cables, a 4.92 ft wired controller and a 12 V power adapter.

Passive cooling and external power

The aluminium enclosure runs without a fan, so operation is silent during normal use. A 12 V DC adapter supplies the switching logic and the four USB 3.0 ports, removing any draw from the connected computers. LED indicators on the front panel show the active computer at a glance.

Wired controller and dual display modes

The supplied 4.92 ft wired remote duplicates the front push buttons, allowing convenient switching from a distance. The switch supports both extended and copy display modes across the two monitors, with the HDMI path handling up to 8K at 60 Hz or 4K at 120 Hz and the DisplayPort path handling up to 8K at 30 Hz or 4K at 144 Hz.

Questions about this item

How do I install the SMA 2-Port HDMI+DP KVM Switch, and which step do people often get wrong?

Connect each computer to both the HDMI 2.1 and DisplayPort 1.4 inputs plus a USB 3.0 cable, then attach the 12 V power adapter; the step most often missed is using certified HDMI 2.1 and DP 1.4 cables kept as short as possible.

What maintenance or replacement will the SMA 2-Port HDMI+DP KVM Switch need later?

No scheduled maintenance is required; only the included 1.5 m USB 3.0 cables or the 4.92 ft wired controller may need replacement if they become damaged.

What limit appears first on the SMA 2-Port HDMI+DP KVM Switch under sustained use?

The DisplayPort path is limited to 8K at 30 Hz or 4K at 144 Hz, while the HDMI path reaches 8K at 60 Hz or 4K at 120 Hz, so the DP bandwidth ceiling is the first constraint.
