Bi-directional USB-C video switch
The LUOM TJ-A034 is a compact bi-directional switch that handles 8K at 30 Hz and 4K at 120 Hz over USB-C. It operates as a 2-in-1-out switch for two source devices sharing one display or as a 1-in-2-out splitter sending one source to either of two monitors. A 50 cm tethered cable connects to the display, while two additional USB-C ports accept host devices. External power via the included micro-USB cable is mandatory for operation.
Suited for dual-PC or laptop-plus-desktop setups
This unit suits users who alternate between two USB-C video sources on a single high-refresh monitor, or who need to route one source to one of two displays without simultaneous output. It supports 10 Gbps data and up to 100 W power delivery for charging the host. Buyers who require both attached monitors active at the same time, or who need HDMI or DisplayPort native outputs, should consider a different device.
Verify host and display USB-C capabilities
Before ordering, confirm that each source device and the monitor provide USB-C ports with DisplayPort Alt Mode video output. The monitor’s USB-C input must support video reception and have the function enabled in its menu. Ensure you can supply the required external power through the provided micro-USB cable. Cable reach is limited to the 50 cm fixed lead, so check placement relative to your screen.

Questions about this item
Does my monitor need a USB-C port that carries video for the LUOM TJ-A034 to drive it?
Yes, the fixed 50 cm USB-C cable must plug into a monitor USB-C port that supports video transfer and has the video function enabled.
Can I keep my existing USB 3.1 Gen 2 cables and still get 10 Gbps data through the switch?
Yes, the switch complies with USB 3.1 and 10 Gbps bandwidth, so Gen 2 cables will pass full speed.
How do I confirm the switch is delivering 100 W power to my laptop after setup?
The laptop should show it is charging at up to 100 W via USB PD 3.0 when the supplied micro-USB power cable is connected to the switch.
