How to use

Connect one end of the cable to a Thunderbolt 4 port on a computer or compatible host and the other end to a Thunderbolt 4 peripheral, monitor or docking station. If using video output, ensure the connected display supports DisplayPort 1.4a modes for the requested resolution and refresh rate. For power delivery, verify that both host and device support USB PD 3.1 and the required EPR profiles before supplying up to 240 W.

Recommendations

Use certified Thunderbolt 4 ports and compatible devices to achieve full performance. Avoid coiling the cable tightly during high-power charging or sustained high data transfer to reduce heat buildup. If a connected device does not negotiate the expected features, check cable endpoints and device firmware for compatibility.
