SMUGDESK 4×2 HDMI 2.0b Matrix Switch 4K@60Hz HDR10 HDCP2.2 Audio Extractor

SKU CH-AVDW-ERB9C

Routes four HDMI sources to two independent 4K 60 Hz displays with HDR10 and extracts audio via coaxial, optical or 3.5 mm outputs

  • Routes any of 4 sources to 2 screens independently
  • 18Gbps HDMI 2.0b delivers 4K at 60Hz with HDR10
  • Extracts audio via Coaxial, Optical and 3.5mm ports
  • Built-in downscaler converts 4K input to 1080P for mixed displays
  • Switch by IR remote or front buttons without drivers

True 4×2 HDMI Matrix Routing

This SMUGDESK switch lets you assign any of four HDMI sources to two independent displays at the same time. Each output can show a different 4K signal or mirror the same source for flexible distribution. It is built for home theatres, conference rooms and digital-signage installations that need simultaneous multi-screen playback. The 18 Gbps HDMI 2.0b backbone keeps 4K 60 Hz 4:4:4, HDR10 and HDCP 2.2 intact across both paths.

Independent Audio Extraction for External Sound

Builders who want to feed a soundbar, DAC or stereo amplifier from the HDMI stream get coaxial, optical and 3.5 mm analogue breakout ports. The audio is stripped without occupying an HDMI output, so both screens stay connected. Users who only need a simple splitter or who require more than two display zones should look at other form factors. No network or serial control is included for centralised automation.

Built-in EDID Downscaler to 1080p

A single specification decides fit: the switch can automatically convert a 4K input down to 1080p for mismatched displays. If your installation mixes 4K and 1080p screens this feature resolves handshake failures instantly. If every display in the chain is native 4K the downscaler remains idle but does not degrade the signal.

Questions about this item

What comes in the box with the SMUGDESK 4×2 HDMI matrix and which cables must I buy separately?

The package includes the matrix unit, an IR remote control and a power adapter. You must supply four HDMI cables for the sources and two HDMI cables for the displays, plus any coaxial, optical or 3.5 mm audio cables you need for extraction.

When should I use the downscaler instead of passing 4K straight through?

Enable the built-in downscaler when one display only supports 1080p while the other handles 4K@60Hz; it converts the 4K input to 1080p for that screen without affecting the 4K output.

Does the 18 Gbps bandwidth guarantee HDR10 and HDCP 2.2 on both outputs at the same time?

Yes, the HDMI 2.0b chipset delivers the full 18 Gbps on each output, so both screens can show 4K@60Hz 4:4:4 with HDR10 and HDCP 2.2 simultaneously.
