Why USB-C Cables That Look the Same Perform Differently

USB-C describes the connector shape, not a single level of performance. Two cables that look nearly identical can support different charging power, data rates, and video capabilities. That is why changing only the cable can sometimes change how quickly a laptop charges or whether an external display works at all.

When replacing a cable for a specific job, match its stated power and data capabilities to the equipment rather than assuming every USB-C cable is interchangeable.
