Triple-monitor KVM for four computers

The Vszerda NW-KVM403DH lets one keyboard and mouse control four computers or laptops across three displays. It adds four USB 3.0 ports at up to 5 Gb/s for shared peripherals such as printers or storage. Driver-free operation works on Windows, macOS and Linux. Switching is handled by front-panel push buttons or the included wired remote with LED indicators. A 5 V power adapter is supplied.

Video interface limits

Each computer must provide two DisplayPort outputs and one HDMI output to drive the three monitors. The switch passes signals up to 8K at 60 Hz and is backward compatible with 4K at 144 Hz, 4K at 120 Hz and 1080p at 240 Hz. HDMI 2.1 and DisplayPort 1.4 cables are recommended for the highest resolutions; shorter cables improve signal integrity. Extended and mirrored display modes are both supported.

Capacity and headroom

Four USB 3.0 ports give enough bandwidth for keyboard, mouse and two additional high-speed devices without bottlenecks. The unit operates reliably up to 50 °C ambient temperature. It handles four systems and three displays simultaneously, but cannot support a fifth computer or a fourth monitor. Buyers needing more than four connected hosts or more than three screens will need a different solution.

Questions about this item

Should I pick the 8K@60Hz or 4K@144Hz capability for my setup?

The switch handles both; 8K@60Hz is the ceiling resolution, while 4K@144Hz, 4K@120Hz and 1080P@240Hz are supported as lower refresh options.

What does 8K@60Hz actually deliver when I connect three monitors to four PCs?

Each of the three displays can run at up to 8K resolution at 60 Hz, provided every computer has two DP 1.4 outputs and one HDMI 2.1 output and you use matching cables.

Which video interfaces are on the box and what bandwidth do they limit me to?

The unit provides one HDMI 2.1 and two DisplayPort 1.4 ports per channel, capping the link at the 8K@60Hz or 4K@144Hz levels listed.
