USB-C to HDMI converter for 4K 60Hz output

The StarTech 109B-USBC-HDMI adapter adds an external display to a laptop or desktop through a single USB-C port. It supports 4K resolution at 60Hz for sharp video playback and multi-tasking. Professionals who need extra screen space while travelling or at a permanent desk will find it useful. The compact dongle draws power from the host connection.

Thermals noise and power draw

The unit is passively cooled and has no moving parts, so it runs silently in normal use. Power is supplied through the USB-C link with Power Delivery pass-through, keeping the host port available for charging. Heat output remains low during typical office workloads and video streaming. No external power brick is required for operation.

Build integration and freed resources

The adapter plugs directly into any USB-C port that supports DisplayPort Alt Mode and Power Delivery. It occupies one port while returning a charging path, so the laptop retains its power input. An HDMI cable completes the link to a monitor, projector or TV. Users who need more than one additional display or a different video interface will need a separate solution.

Questions about this item

How do I connect the STARTECH 109B-USBC-HDMI to my laptop for dual 4K 60Hz displays?

Plug the single USB-C connector into a port that supports video and Power Delivery, then attach two HDMI cables to the adapter's outputs; the step often missed is confirming the host port carries DisplayPort Alt Mode and enough power for both monitors.

What part of the STARTECH 109B-USBC-HDMI is most likely to need replacement after heavy daily use?

The integrated USB-C cable and its strain relief see the most physical stress; if the connector loosens or the cable frays, the whole adapter must be replaced because the cable is not detachable.

What limit appears first when driving two 4K 60Hz screens continuously through the STARTECH 109B-USBC-HDMI?

Thermal throttling from sustained bandwidth load can reduce frame stability before any firmware or port limit is reached, especially if the adapter sits in a confined space with no airflow.
