Does USB-C Support Monitors?
USB-C is a connector shape, not a guarantee of video output. Whether a given USB-C port can drive a monitor depends on which protocols that specific port implements — and not every USB-C port on a laptop necessarily supports the same set.
What actually carries video
Video over USB-C requires DisplayPort Alt Mode (or, on some docks, Thunderbolt/USB4, which carries DisplayPort as one of the protocols it tunnels). A USB-C port that only implements USB data and charging — with no DP Alt Mode, Thunderbolt, or USB4 support — will not output video no matter what cable or adapter is used.
How to check a specific port
Manufacturer spec sheets typically list this per-port rather than assuming every USB-C port behaves the same — look for "DisplayPort Alt Mode," "DP over USB-C," "Thunderbolt," or "USB4" next to the specific port. A laptop with multiple USB-C ports may have video output on only one of them.
Cables and adapters
Even when a port supports DP Alt Mode, using a USB-C cable that's only rated for USB 2.0 data/charging (common on cheap charging-only cables) can fail to carry the video signal. A full-featured USB-C cable, or the adapter/dock's own captive cable, is generally the safer choice.
