Vszerda 8K Dual Monitor KVM Switch 4 Computer 2 Monitors

Four-computer dual-monitor control

This KVM switch lets one keyboard, mouse and dual-monitor set manage four computers while sharing four USB peripherals. It supports both copy mode, where both screens show the same image, and extend mode, where each screen shows a different desktop, provided each source has two HDMI outputs. The unit works with Windows, Vista, XP, Mac OS, Linux and Unix without driver installation. Switching is done via front-panel buttons or the included wired remote, with LEDs indicating the active system.

Sustained 8K60 and 5Gbps throughput

The switch maintains video bandwidth up to 8K at 60Hz and is backward compatible with 4K60 and 1080P signals during continuous operation. Three USB 3.0 ports deliver up to 5Gbps transfer speeds for attached storage or peripherals, while a dedicated USB 2.0 port is reserved for 2.4GHz wireless dongles to avoid interference. The 12V power adapter ensures stable performance across all four connected computers and shared devices without signal degradation over time.

Verify dual-HDMI sources and cable budget

Each computer must provide two HDMI outputs to use extend mode; single-HDMI systems can only use copy mode or a single monitor. No HDMI cables are included, so you need eight male-to-male cables for the four dual-HDMI inputs plus two more for the monitor outputs. Confirm that your graphics cards support the desired resolution and refresh rate combination before ordering.
