4×2 HDMI 2.0 Matrix Switch

This four-input, two-output HDMI 2.0 matrix routes any source to either display independently, letting two screens show the same or different 4K content. It suits home-theatre owners, multi-console gamers and small meeting rooms that need flexible source distribution without rewiring.

Metal shell with gold-plated ports

A sturdy metal enclosure and gold-plated connectors reduce signal loss during continuous operation. Independent SPDIF 5.1, coaxial and 3.5 mm stereo outputs de-embed audio for amplifiers or speakers, while ARC returns TV audio via SPDIF or coaxial without an extra cable.

Check your sources, displays

Verify that each source outputs HDMI 2.0 signals and that both displays accept 4K at 60 Hz with HDCP 2.2. Ensure you have enough HDMI cables for four inputs and two outputs, plus any SPDIF, coaxial or 3.5 mm leads required for the audio extraction paths you plan to use.

Questions about this item

What does the 18Gbps HDMI 2.0 bandwidth cap in practice?

It caps native 4K resolution at 60Hz with full 4:4:4 chroma sampling, HDR support and HDCP2.2 compliance for protected UHD content.

What physical space and connections does the metal enclosure need?

The unit needs room for four HDMI inputs, two HDMI outputs plus SPDIF, coaxial and 3.5mm audio ports; its metal shell and gold-plated connectors are designed for stable desktop or rack placement.

How is the matrix configured and which step is often missed?

Use the IR remote or front panel buttons to assign any input to either output, then set the adjustable EDID to match each display — skipping EDID setup is the common cause of no-signal or wrong-resolution issues.
