Bi-Directional HDMI 2.1 Switch

The LUOM TJ-A041 routes HDMI 2.1 signals in either direction. Use it as a 2-in-1-out switch to select between two sources on one 8K display, or as a 1-in-2-out splitter to send a single source to one of two screens. Gamers with a PS5 or Xbox Series X and professionals juggling multiple devices both benefit from the 48 Gbps bandwidth.

Passive Operation With Status LEDs

The unit draws power from an included DC 5 V line and runs without audible fans. Dual indicator lights show the active port at a glance. With no moving parts and a compact 12 x 6 x 0.08 inch form factor, it adds negligible heat to a desk or media cabinet while maintaining full 8K@60 Hz and 4K@120 Hz throughput.

Simple Integration For Two Displays Or Sources

Connect up to three metres of certified HDMI 2.1 cable on each side to preserve signal integrity at 48 Gbps. The switch supports Dolby Vision, HDR10, HDCP 2.2 and 2.3, plus DTS-HD Master Audio and DTS:X pass-through. Only one output displays at a time, so buyers needing simultaneous dual-monitor output should choose a different solution.

Questions about this item

How do I install the LUOM TJ-A041 HDMI 2.1 switch and what step do people often miss?

Connect up to two HDMI sources to the two input ports, or one source to the single input for splitter mode, then attach the display to the output. The step often missed is plugging in the included DC 5V power line; the unit needs external power for reliable 48Gbps operation.

What maintenance or replacement will the LUOM TJ-A041 switch need later?

No scheduled maintenance is required. Keep the ventilation slots clear and avoid bending the attached cables beyond a gentle curve. If the indicator LEDs stop showing the active port or signal drops appear, replace the unit.

What limit appears first on the LUOM TJ-A041 during sustained 8K@60Hz use?

The HDMI 2.1 specification caps cable runs at 3 metres on each side of the switch. Exceeding that length causes signal degradation before the 48Gbps bandwidth or the PI3HDX1221 chip’s 12,000 operations per second become limiting factors.
