LUOM TJ-A034 bi-directional USB-C video switch
The LUOM TJ-A034 is a bi-directional USB-C switch that operates as a 2×1 selector for two source devices sharing one display or as a 1×2 splitter sending one source to either of two monitors. It supports video resolutions up to 8K at 30 Hz and 4K at 120 Hz alongside high-speed data and power delivery. The compact unit is aimed at users who need to toggle between laptops, desktops or Thunderbolt devices on a single USB-C monitor.
Check your monitor and cables before ordering
Verify that your monitor’s USB-C port accepts video input and that the video function is enabled in its on-screen menu. The switch requires external power via the included micro-USB cable; without it no image will appear. You must supply two USB 3.1 Gen 2 cables to connect your source devices to the switch’s two USB-C ports. The fixed 50 cm lead reaches the display.
Thermals noise and power in normal use
The aluminium-bodied switch runs passively with no fan, so it adds no audible noise to a quiet workspace. It draws the few watts needed for its own logic from the supplied micro-USB connection while passing up to 100 W of USB Power Delivery through to the host. Typical operation stays warm to the touch but does not throttle or require additional cooling.

Questions about this item
Does the LUOM TJ-A034 include the cables needed to connect my two laptops and one monitor, or must I buy them separately?
The box contains the bi-directional switch with a fixed 50 cm USB-C cable and a Micro-USB-to-USB power cable; you must supply two USB 3.1 Gen 2 USB-C cables to link your source devices.
The specs list 8K@30 Hz, 4K@120 Hz and 1440p@165 Hz — which mode should I pick for my setup?
Choose the highest resolution and refresh rate that both your source device and monitor support; the switch simply passes the signal up to 10 Gbps bandwidth.
What does the 10 Gbps bandwidth mean when I plug this switch between my laptop and 4K@120 Hz display?
It provides enough throughput for 4K@120 Hz video, 100 W power delivery and USB 3.1 Gen 2 data simultaneously over the single USB-C link.
