Can a USB-C charging cable carry 4K video?

Usually no — video needs high-speed lanes and DP Alt Mode, which charge-only cables do not have.

Answer: usually not. Video over USB-C needs high-speed lanes plus DisplayPort Alt Mode support; a charge-only cable has neither.

Check the cable is rated for USB 3.2 / USB4-class data, not just power.
Check the host port supports DP Alt Mode — a charging-only port will not output video whatever the cable.
4K60 needs more lanes than 4K30; state the resolution and refresh in the requirement.

Our USB-IF membership has since lapsed, so that entry is no longer in the public USB-IF product search; the certificate itself is published on our credentials page.
