What this switch does

The LUOM TJ-A034 is a bi-directional USB-C video switch that works as either a 2×1 selector or a 1×2 splitter. It lets you route one source between two displays or choose between two sources on a single display. External power via the supplied micro-USB cable is required for operation.

Resolution and bandwidth limits

The single specification that decides fit is the maximum video capability: 8K at 30 Hz or 4K at 120 Hz over a 10 Gbps link. Lower resolutions such as 1440p at 165 Hz or 1080p at 165 Hz are also supported within the same bandwidth envelope.

Thermals noise and power

The unit draws up to 100 W of USB Power Delivery 3.0 pass-through for connected devices while consuming minimal power itself. It has no fan, so operation is silent and the aluminium casing stays cool during normal switching use.

Questions about this item

What does the 10Gbps bandwidth mean for my monitor setup?

The 10Gbps bandwidth carries DisplayPort 1.4 video up to 8K at 30Hz or 4K at 120Hz, plus USB 3.1 Gen 2 data and up to 100W power delivery over the same USB-C cable.

Which USB-C standard caps the video and data performance?

USB 3.1 Gen 2 with DisplayPort 1.4 alt-mode sets the 10Gbps ceiling; Thunderbolt devices work but run at this switch's 10Gbps limit.

What does the 50cm fixed cable and 12 x 6 x .08 inch body need to fit my desk?

The 50cm tether reaches a nearby monitor port, the slim 12 x 6 x .08 inch enclosure sits flat, and the micro-USB power input must reach a USB charger or port.
