Three-monitor KVM for dual computers

This Vszerda KVM switch lets two desktops or laptops share one keyboard, one mouse and three displays connected through one HDMI and two DisplayPort outputs. Each source must be able to drive three independent screens for extended or mirrored layouts. The unit is powered by an included 12 V adapter.

Video bandwidth and switching

The HDMI output handles up to 8K at 60 Hz, 4K at 120 Hz, 3440 x 1440 at 144 Hz and 1080p at 240 Hz. Each DisplayPort output supports 8K at 60 Hz, 4K at 144 Hz, 3440 x 1440 at 144 Hz and 1440p at 165 Hz. Users change the active computer with a front-panel button or the wired remote control.

Four USB 3.0 ports and cable routing

Four downstream USB 3.0 ports run at 5 Gbps and accept keyboards, mice, printers or other peripherals, all switchable between the two hosts. All video and USB cables plug into rear-facing ports, keeping the desktop clear of clutter. The switch works with Windows, Linux and macOS without extra drivers.

Questions about this item

How do I connect two laptops to three monitors using the HDMI and two DisplayPort inputs, and what step is often missed?

Connect each laptop to the HDMI IN 1A, DP IN 1B, and DP IN 1C inputs with matching cables, then attach monitors to the HDMI and two DP outputs; the step often missed is plugging in the 12 V power adapter before switching.

Which ports or cables will need replacement first with daily switching between two computers?

The HDMI and DisplayPort cables plugged into the input ports see the most wear from repeated unplugging; the front-panel button and wired remote are rated for long-term use but the cables are the practical maintenance point.

What resolution and refresh-rate ceiling will I hit first when gaming at 4K across all three monitors?

The DisplayPort outputs max out at 4K 144 Hz while the HDMI output reaches 4K 120 Hz, so the HDMI-connected monitor will hit its refresh ceiling first during sustained high-frame-rate gaming.
