Dual-Monitor DP 1.4 KVM Switch

This DisplayPort 1.4 KVM switch lets two computers share one keyboard, one mouse, two monitors, audio, microphone and two USB 3.0 peripherals. It is built for users who need to move between a work machine and a personal system without re-plugging cables. The metal housing keeps the unit stable on a desk.

Resolution and refresh limits

The switch supports a maximum resolution of 7680x4320 at 30 Hz, 3840x2160 at 144 Hz and lower combinations such as 5K at 50 or 60 Hz and 2K at 144 Hz. HDR10 pass-through is included. Final output depends on the graphics cards and monitors connected, so the highest modes may not be reachable with every hardware pair.

Installation notes

Four switching methods are available: push buttons on the unit, a wired remote button, keyboard hotkeys and mouse gestures. The package supplies all required cables except the monitor leads, which normally ship with the displays. Power everything off first, then power the KVM, then the monitors, then the computers in that order to avoid detection issues.

Questions about this item

Should I choose the 4K 144 Hz or 8K 30 Hz mode for my dual monitors?

The switch supports both 3840x2160 at 144 Hz and 7680x4320 at 30 Hz simultaneously on two displays; pick the resolution and refresh rate that matches each monitor’s native capability.

What does the 7680x4320 resolution actually deliver on my PC?

It provides an 8K signal at 30 Hz per DisplayPort output, so you can run one or both monitors at that resolution provided your graphics cards and cables support DP 1.4 bandwidth.

How does the DisplayPort 1.4 interface limit what I can connect?

DP 1.4 caps each video link at 8K 30 Hz or 4K 144 Hz, and the USB 3.0 hub shares 5 Gbit/s bandwidth for peripherals across the two computers.
