4x4 HDMI Matrix Switch for multi-source

The LUOM OZJ4 routes four HDMI sources to four independent displays so each screen can show a different input or the same signal. It handles 4K at 60 Hz with 18 Gbps bandwidth and HDCP 2.2 compliance. Deep-colour support at 8, 10, 12 and 24 bit preserves colour accuracy for compatible sources. The unit measures 230 by 90 by 25 mm and weighs 11.9 ounces.

IR remote and EDID management simplify operation

An included IR remote lets you change routing without reaching the switch. EDID learning copies the capability of a connected display, while pre-programmed EDID tables cover common formats; after any EDID change a restart of the switch is required. Independent audio extraction on each output provides both optical and stereo headphone paths for external sound systems.

Verify cable lengths and source compatibility

Input and output cables must not exceed 8 metres when using AWG 26 HDMI 2.0b cables to maintain the 18.5 Gbps data rate. Confirm that each source device outputs a resolution and refresh rate within the 3840 by 2160 at 60 Hz limit and that your displays accept HDCP 2.2. The switch requires a power supply; ensure a suitable outlet is available near the installation point.

Questions about this item

How often will the IR remote control need its batteries replaced?

The IR remote uses standard button-cell batteries; typical life is many months of daily switching, and replacement takes seconds when the range shortens.

What limits the 18.5 Gbps bandwidth during a full-day 4K 60 Hz session?

The 18.5 Gbps ceiling is set by the HDMI 2.0b TMDS clock at 600 MHz; sustained 4K 60 Hz 4:4:4 signals run at that limit continuously.

Does the unit get hot or draw much power when all four outputs run 4K 60 Hz all day?

The aluminium chassis passively dissipates the low heat from the 18 Gbps switching engine; no fan is fitted and power draw stays modest.
