4x4 HDMI Matrix for multi-display routing

The ESTONE OZJ4 is a 4x4 HDMI matrix switch that routes four source devices to four displays independently. It suits installers and enthusiasts who need flexible signal distribution across multiple monitors or projectors in home-theatre, classroom or digital-signage setups.

Verify HDMI 2.0b ports

Each of the four inputs and four outputs uses an HDMI 2.0b connector with HDCP 2.2 support. Source devices and displays must provide HDMI 2.0b outputs and inputs respectively, and cable lengths should stay below eight metres using AWG26-rated leads to maintain the 18.5 Gbps bandwidth at 4K@60Hz.

IR remote and EDID learning simplify

The bundled infrared remote lets you switch or split inputs from a distance without front-panel buttons. Built-in EDID extraction and pre-programmed EDID profiles automatically negotiate the correct resolution and deep-colour format up to 12-bit, reducing handshake failures when sources and displays have mismatched capabilities.

Questions about this item

Does the ESTONE OZJ4 package include HDMI cables or must I buy them separately?

The package contains only the 4x4 HDMI matrix unit; four input and four output HDMI cables need to be purchased separately.

Should I choose the EDID learning mode or a pre-programmed EDID for my 4K@60Hz displays?

Use EDID learning when a connected display reports its capabilities correctly; switch to a pre-programmed EDID if a source refuses to output 3840x2160@60Hz YUV4:4:4.

What does the 18.5Gbps bandwidth mean for a real 4K@60Hz setup?

It carries full 4K@60Hz 4:4:4 8-bit video with HDR; 10-bit or 12-bit deep colour at 60Hz would exceed the 18.5Gbps limit.
