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.
