USB-C to HDMI adapter for 4K output

The Cables To Go 29474 connects a USB Type-C port to an HDMI display, supporting 3840x2160 resolution at 30Hz. It carries both audio and video signals to compatible HDTVs or projectors. The compact black adapter suits bring-your-own-device setups in education or corporate spaces. It requires a host port with native video-out capability.

Passive conversion with no active cooling

As a passive adapter, it draws minimal bus power and has no active components to throttle under sustained load. Video delivery remains stable for the duration of a session, limited only by the host controller and cable quality. There is no onboard processor or memory to saturate during extended use. Performance is consistent for static content and standard desktop workflows.

Silent operation with negligible power draw

The unit produces zero audible noise because it contains no fan or moving parts. Heat generation is negligible, so the housing stays near ambient temperature during normal operation. Power consumption is limited to the signalling requirements of the USB 3.1 interface. No external supply is needed, and the adapter adds no measurable thermal load to the host system.

Questions about this item

Does the USB 3.1 Type C to HDMI adapter generate noticeable heat or noise when driving a 3840x2160 display at 30Hz all day?

The passive adapter has no fan or active electronics, so it runs silently and produces only minimal warmth during continuous 4K 30Hz use.

Must my laptop or tablet provide a USB-C port with DisplayPort Alt Mode for the C2G 29474 to work?

Yes, the host USB-C port must support DisplayPort Alternate Mode to carry the video signal; a data-only USB-C port will not drive the HDMI output.

Will this adapter downscale 3840x2160 at 30Hz correctly on an older 1080p projector or HDTV?

The adapter passes the native 4K 30Hz stream, and the connected display handles any downscaling to its own maximum resolution automatically.
