4-Port HDMI KVM Matrix Switch

This 4x2 HDMI KVM matrix routes video from four source devices to two independent displays at up to 3840x2160 resolution and 60 Hz refresh rate. It supports HDMI 2.0 and HDCP 2.2 for protected content playback. Each output provides separate audio extraction via optical SPDIF or 3.5 mm jack. Four USB cables are included for keyboard and mouse connectivity across all connected systems.

Dual-monitor operators and multi-system managers

The matrix suits users who need simultaneous, independent display of different sources on two screens, such as control rooms, training suites or content-creation desks. It also fits setups requiring shared keyboard and mouse control across four computers. Buyers who only need single-monitor switching or who require more than four inputs should consider alternative configurations.

Installation notes and common issues

The unit connects via standard HDMI and USB cables, with switching available through front-panel buttons, the supplied infrared remote or configurable keyboard hotkeys. No software drivers are required for basic operation. Ensure source devices output compatible HDMI 2.0 signals; older HDCP versions may block protected content. Verify monitor EDID handshake if a display fails to show an image after switching.

Questions about this item

What HDMI cables and USB cables do I need to connect four computers and two monitors to this KVM matrix?

You need four HDMI 2.0 cables for the computer inputs and two HDMI 2.0 cables for the monitor outputs; the box includes four USB cables for keyboard and mouse connections.

Will my existing 1080p monitors and older HDMI 1.4 sources work with the 4K 60 Hz HDMI 2.0 and HDCP 2.2 specification?

Yes, the matrix is backward compatible with lower resolutions and earlier HDMI and HDCP versions, so 1080p displays and HDMI 1.4 devices will function normally.

How can I verify that the matrix is delivering 3840x2160 at 60 Hz with 4:4:4 colour to each monitor after setup?

Check the on-screen display or graphics control panel on each connected computer to confirm the active resolution reads 3840x2160 at 60 Hz with RGB or YUV 4:4:4 colour format.
