What this HDMI 2.1 switch does

The LUOM TJ-A041 is a bi-directional HDMI 2.1 switch that operates as a 2-in-1-out switcher or a 1-in-2-out splitter. It connects two source devices to one display or one source to two displays, switching between them with a button. Only one output is active at a time.

Bandwidth and resolution limits

The unit passes up to 48 Gbps, supporting 8K at 60 Hz and 4K at 120 Hz for high-refresh gaming or detailed media playback. It handles Dolby Vision, HDR10, HDCP 2.2 and 2.3, plus DTS-HD Master Audio and DTS:X. Cables on each side should not exceed 3 metres for reliable 8K transmission.

Build integration and power needs

The compact black enclosure measures 12 by 6 by 0.08 inches and weighs 1.2 ounces, fitting easily behind a monitor or in a media cabinet. A DC 5 V power line is included to drive the PI3HDX1221 chip, which manages 12,000 operations per second. Dual indicator lights show the active port at a glance.

Questions about this item

Will the LUOM TJ-A041 pass 4K 120 Hz from my new console to an older 4K 60 Hz TV without manual downscaling?

The switch supports 4K@120Hz input and intelligently outputs a compatible picture, so a 4K 60 Hz display will receive a signal it can handle.

How do I confirm the LUOM TJ-A041 is actively passing an 8K 60 Hz signal after I press the switch button?

Dual indicator lights show the active port and work status at a glance, confirming the selected 8K@60Hz path is live.

Does the LUOM TJ-A041 box include HDMI cables for the two inputs and one output, or must I buy them separately?

The package contains the bi-directional switcher, a DC 5V power line and instructions; HDMI cables are not included and must be purchased separately.
