4 Port VGA USB KVM Switch

The StarTech SV431USB lets you command up to four PC or Mac computers from one keyboard, mouse and VGA monitor. A built-in USB hub shares any connected USB device across all four systems. Solid steel construction supports desktop or rack mounting for professional environments.

Ideal for users who need simultaneous USB peripheral sharing alongside video switching. Not suitable for buyers who require digital video interfaces such as DVI, HDMI or DisplayPort. Also not suited for setups needing more than four computer connections or higher resolutions beyond 1920 x 1440.

Simple installation with push-button and hotkey

Connect each computer using the supplied VGA and USB cables, attach the console peripherals, then power the unit via the 5 V DC adapter.

Questions about this item

What console-side connectors do I need on my keyboard, mouse and monitor to use the SV431USB?

The console side provides one 8-pin DIN female for keyboard, one 8-pin DIN female for mouse and one high-density DB15 female for the VGA monitor.

Can I keep my older PS/2 keyboard and mouse when connecting four USB-only computers to this switch?

Yes. Each computer connects through a USB-B port and a high-density DB15 VGA port, while your PS/2 keyboard and mouse plug into the console DIN ports.

How can I verify the switch is scanning correctly after I power it on?

Press the front push-buttons to cycle through the four ports; the active port LED will change and the attached computers will display at 1920 x 1440 resolution.
