What it is and who it is for

The StarTech SV431HDU3A2 is a 4-port HDMI KVM switch with an integrated USB 3.0 hub. It lets one operator control four separate computers from a single monitor, keyboard, mouse and speaker set. The unit is aimed at IT administrators, developers and multi-system workstations that need to share peripherals without unplugging cables.

The specification that decides fit

Video support tops out at 1920 x 1080 at 60 Hz, so the switch is unsuitable for 1440p, 4K or high-refresh-rate displays. Each host connects through one HDMI input, one USB Type-B 3.0 link and a 3.5 mm audio jack; the console side provides one HDMI output, four USB Type-A 2.0 ports and one 3.5 mm audio output.

Installation and common issues

The device draws power from an included 12 V DC adapter that accepts 100 to 240 V AC, and switching is done by front-panel push buttons or configurable hot-key sequences. No drivers are required on the host computers. Buyers sometimes forget that the console USB ports are limited to 2.0 speeds even though the upstream link is 3.0, and that only two-channel stereo audio is passed through the 3.5 mm connections.

Questions about this item

What does the 1080p 60 Hz rating mean when I connect four computers to one monitor?

The switch passes up to 1920 x 1080 at 60 Hz from whichever computer is active, so the console monitor shows that resolution without scaling.

How does the USB 3.0 host port and the four USB 2.0 console ports work together in practice?

The single USB 3.0 Type-B upstream link carries keyboard, mouse and hub traffic at 5 Gbps, while the four Type-A downstream ports provide USB 2.0 connections for peripherals.

What clearance and power connections does the unit need to sit on a desk?

It measures 8.70 x 5.10 x 1.70 inches and weighs 3.55 lbs, and it ships with a 100–240 V AC adapter that delivers 12 V DC at 1.5 A.
