4-Port HDMI KVM with Dual 4K 30Hz

This new StarTech.com SV431DHD4KU switch lets one operator command four HDMI computers from a single keyboard, mouse and two monitors. Each console screen can show 3840 x 2160 at 30 Hz. The box includes a universal AC adapter and rubber feet for desktop placement. No drivers or software are needed on any host.

Suits admins running four workstations

Not for users who need higher than 30 Hz refresh at 4K, nor for setups that require more than four computer ports. Builders without dual-display consoles will leave one HDMI output unused. Environments above 40 °C or below 0 °C fall outside the rated operating range.

Dual 4K 30Hz over two HDMI console ports

The defining spec is the pair of HDMI console outputs that each support 3840 x 2160 at 30 Hz, letting two monitors run at that resolution simultaneously from any of the four connected computers.

  • Dual 4K 30 Hz video on two HDMI displays

Questions about this item

How do I connect both monitors and all four computers to the SV431DHD4KU, and which step is most often missed?

Connect each computer using two HDMI cables and one USB 3.1 Type-B cable, then link the console HDMI outputs to your monitors; the step most often missed is plugging in the separate USB 3.1 Type-B cable for each host so the keyboard, mouse and USB 3.0 peripherals actually switch.

What maintenance or replacement will the SV431DHD4KU need over time?

The unit has no user-serviceable parts; keep the ventilation slots clear and operate within the 0 to 40 °C and 0 to 80 % humidity range, and replace only the external 12 V DC power adapter if it ever fails.

What limit appears first when the SV431DHD4KU runs continuously at full load?

The 18 W power budget and 1.5 A DC output cap are reached before thermal limits, so sustained use with all four hosts and both USB 3.0 ports active will hit the adapter’s current ceiling first.
