Four-computer KVM control

This Vszerda HDMI KVM switch lets one monitor, keyboard and mouse manage four computers. It supports video up to 4K resolution at 30 Hz and carries USB 2.0 signals for shared peripherals. A wired desktop controller and front-panel buttons both change the active system instantly. The unit draws power from the connected hosts so no external adapter is required.

Check host ports and cable reach

Each computer must provide an HDMI output and a USB 2.0 type-A port for the included 1.5 m combination cables. Verify that your four systems run a supported OS such as Windows 10 or 11, Mac OS, Linux, Unix or DOS. The switch adds three USB 2.0 ports on the front for shared devices like a printer, scanner or flash drive. No driver installation is needed on any host.

Single-screen, shared-peripheral hub

Connect the four 2-in-1 cables to the switch inputs and the monitor to the single HDMI output. Plug keyboard, mouse and up to two more USB 2.0 devices into the front hub so all four computers share them. Hot-plug support lets you attach or remove hosts without powering down. The compact switch sits on the desk and keeps cabling tidy with the bundled 1.5 m cables.

Questions about this item

What cables and accessories are included, and do I need to buy anything else to connect four computers?

The box contains the 4-port KVM switch, four 1.5 m 2-in-1 HDMI-plus-USB cables, a wired desktop controller and a user manual. Each computer plugs directly into one of the supplied cables so no extra cables are required for a four-system setup.

Which video resolution and refresh rate does the switch support, and is there a higher-spec version to choose from?

The unit handles up to 4K at 30 Hz; the product data lists only this single version so there is no alternative capacity or refresh-rate option to select.

When I run a 4K monitor at 30 Hz through the switch, will I see any drop in image quality or input lag?

The switch passes 4K 30 Hz video natively with no driver installation, so the monitor receives the same signal it would get from a direct HDMI connection. USB 2.0 peripherals share the same 3-port hub, adding no perceptible latency for keyboard and mouse use.
