Vszerda 4-Port Dual Monitor KVM Switch

The Vszerda 4-port dual monitor KVM switch lets four computers share two HDMI displays and three USB 3.0 peripherals with one keyboard and mouse set. It supports duplicate, extend and spliced output modes depending on the host graphics card. Plug-and-play operation requires no driver installation across Windows, Mac, Linux and Unix systems. Switching is handled by front-panel buttons or the included wired remote control.

HDMI 2.1 8K@60Hz 4K@144Hz Video Bandwidth

The single specification that determines compatibility is the HDMI 2.1 interface delivering 8K at 60 Hz and 4K at 144 Hz, with backward compatibility down to 1080p. Both monitor outputs maintain this bandwidth simultaneously so each connected PC can drive high-refresh or high-resolution content without downscaling. If a source cannot output HDMI 2.1 timings the switch will fall back to the highest common mode automatically.

Sustained Multi-PC Operation

Under continuous use the switch maintains stable video and USB 3.0 data paths across all four inputs without thermal throttling or signal dropout. The three USB 3.0 ports sustain 5 Gbps throughput for storage or peripherals while the additional USB 2.0 port handles legacy devices. Remote and button switching remain responsive during extended sessions, keeping workflows uninterrupted for multi-system setups.

Questions about this item

What does the 8K@60Hz rating mean when I connect two monitors to this KVM?

The switch can pass an 8K signal at 60 Hz to each of the two outputs, so both monitors can show 8K content simultaneously, provided your graphics cards and cables also support that bandwidth.

Which HDMI version does the switch use and what refresh rates does it actually allow at 4K?

It uses HDMI 2.1, enabling 4K at 144 Hz and 120 Hz as well as 8K at 60 Hz, with backward compatibility for 4K at 60 Hz and 1080p.

What cables and ports do I need on each computer to use the dual-monitor and USB sharing features?

Each PC needs two HDMI outputs (one for “HDMI IN A1” and one for “HDMI IN B1”) plus a USB-A port for the upstream cable; the switch provides three USB 3.0 downstream ports and one USB 2.0 port for shared peripherals.
