4-Port USB 3.0 HDMI KVM Switch

This new USB 3.0 HDMI KVM switch lets one monitor, keyboard and mouse control four computers. It also shares four USB 3.0 peripherals such as a printer or wireless receiver across those systems. The unit is aimed at home offices, families and light-duty workstations that need to toggle between several PCs without extra cables.

Suited for multi-PC desks.

Buyers who want to drive two or more displays from the same four computers should look elsewhere, as the switch provides only a single monitor output. Users who need powered USB ports for high-draw devices will also need a different solution because the unit draws power from the connected computers alone.

Maximum video resolution 3840 x 2160 at 60 Hz

The decisive specification is the maximum supported video resolution of 3840 x 2160 at 60 Hz. If your workflow requires higher refresh rates at that resolution, or resolutions beyond 3840 x 2160, this KVM switch will not meet the requirement.

Questions about this item

How can I confirm the SMA 4-Port KVM Switch is passing 4K@60Hz after I connect everything?

The LED for the active port lights up, and your monitor's on-screen display should report 3840 x 2160 at 60 Hz.

Which cables and accessories are included, and what must I supply myself?

The box contains the switch, one HDMI 2.0 cable (1.5 m), four USB 3.0 cables (1.5 m), a wired remote (1.5 m), a power adapter and a manual. You only need to provide the monitor, keyboard, mouse and four computers.

Should I choose the push-button or the wired remote for switching between my four PCs?

Both methods are included; the panel buttons give tactile feedback at the switch, while the 1.5 m wired remote lets you change ports from your desk without reaching.
