Two-computer KVM with 8K HDMI 2.1

This KVM switch lets you operate two computers from one keyboard, mouse and monitor. It accepts two HDMI 2.1 sources and routes the selected signal to a single display. Switching is done by a front-panel button or a keyboard hotkey, so you can move between systems without unplugging cables. The unit is aimed at users who need a clean desk shared by a work laptop and a gaming rig.

48 Gbps bandwidth with four USB 3.0 ports

The HDMI 2.1 path delivers 48 Gbps throughput, supporting 8K at 60 Hz, 4K at 120 Hz, YUV 4:4:4 and HDR 10 with HDCP 2.3 compliance. Four downstream USB 3.0 ports share peripherals such as keyboards, mice, scanners, gamepads, card readers, printers and webcams between the two connected PCs. A dark-grey enclosure keeps the cabling tidy on a crowded desktop.

Replaces manual cable swapping for dual-PC setups

If you currently unplug and replug HDMI and USB cables to switch machines, this switch removes that wear and delay. The upgrade is worthwhile when both sources need 8K 60 Hz or 4K 120 Hz output and you want shared USB 3.0 accessories without a separate hub. It does not suit setups that require more than two computers or displays with resolutions beyond 8K 60 Hz.

Questions about this item

What does the HDMI 2.1 connection cap at for 8K and 4K refresh rates?

The HDMI 2.1 link runs at 48 Gbps and supports 8K at 60 Hz and 4K at 120 Hz with YUV 4:4:4 chroma, HDCP 2.3 and HDR 10.

What cables and space are needed to connect two computers and four USB 3.0 devices?

Two HDMI cables from the computers to the switch inputs, one HDMI cable from the switch output to the monitor, and USB cables from each computer to the two upstream USB 3.0 ports; four downstream USB 3.0 ports remain for peripherals.

How do I switch between the two computers and what is the common mistake?

Press the front button or use the hotkey combination; the common mistake is forgetting to connect both upstream USB cables, which leaves keyboard and mouse control active on only one computer.
