Two-source HDMI 2.1 switch for one display

The LUOM TJ-A002 routes two HDMI sources to a single screen, supporting 8K at 60 Hz and 4K at 120 Hz with 48 Gbps bandwidth. It is built for users who need to share one monitor or projector between a console, a PC or a media box without unplugging cables.

Passive cooling and USB-powered operation

The aluminium-alloy chassis dissipates heat without a fan, so the unit runs silently on a desk or in a rack. Power comes from the included USB-A-to-Micro-B cable; the switch will not pass a signal until that cable is connected to a live USB port.

Compact metal build with front-panel switching

The 70 × 51 × 13 mm black enclosure weighs 60 g and fits behind most displays. A tactile button on the front toggles between inputs in under a second, while blue LEDs show the active port. The device is strictly 2-in-1-out and cannot be used in reverse.

Questions about this item

How do I install the LUOM TJ-A002 HDMI 2.1 switch and what step is often missed?

Connect both source devices to the two HDMI inputs and the display to the single output, then plug the included USB A to Micro B cable into a powered USB port to supply the required external power; the unit will not pass any signal without this power connection.

What maintenance or replacement will the LUOM TJ-A002 need over time?

The switch itself has no user-serviceable parts or consumables; long-term reliability depends on keeping the USB power cable and both HDMI cables firmly seated and free from dust or physical stress.

What is the first limit I will hit when running the LUOM TJ-A002 at 8K 60 Hz continuously?

The 48 Gbps bandwidth ceiling of the HDMI 2.1 implementation is the primary limit; sustained 8K 60 Hz 4:4:4 content requires the full 48 Gbps link, so cable quality and length must support that rate without signal degradation.
