2×2 HDMI KVM Switch for Dual 4K 60 Hz Displays

This 2×2 HDMI matrix switch connects two computers to two monitors simultaneously. It handles 4K at 60 Hz, 1080p at 144 Hz and 1080p at 120 Hz over HDMI 2.0 with HDCP 2.3 compliance. USB 3.0 peripheral sharing and a 3.5 mm audio jack are built in.

Ideal for multi-system desk setups.

Professionals running a laptop and a desktop side by side can switch both displays together using front-panel buttons, hot-keys or the supplied remote. The semi-DDM USB mode supports wired, wireless and gaming keyboards and mice with near-zero latency. Buyers who only need one monitor or who require more than two computer ports should consider a different unit.

Driver-free installation with cables included

The package provides two USB cables, one USB-C cable, a remote control and a manual so most users can connect everything without extra purchases. No external power adapter is required. The remote ships without the two AAA batteries it needs, and hot-key sequences vary by operating system, so allow a few minutes to learn the switching method.

Questions about this item

What cables must I already have to connect two computers and two monitors to this 2x2 HDMI KVM switch?

You need four HDMI cables — two from each computer to the switch inputs and two from the switch outputs to your monitors — plus the two supplied USB cables and the supplied USB-C cable for computer connections.

Will my older 1080p monitors running at 120 Hz or 144 Hz work alongside a 4K 60 Hz display on this switch?

Yes — the switch supports 1080p at 120 Hz and 144 Hz as well as 4K at 60 Hz, so mixed-resolution dual-monitor setups work without extra configuration.

How do I confirm the switch is passing 4K 60 Hz video and USB 3.0 data correctly after setup?

Check that each monitor shows 3840 x 2160 at 60 Hz in its OSD or OS display settings, verify USB 3.0 device speeds in Device Manager or System Information, and use the front-panel LEDs and hot-key switching to confirm active ports.
