Tips

To get the most out of this dock, ensure your laptop has a Thunderbolt 5 port. For dual 4K displays at 120Hz, use the DisplayPort and HDMI outputs simultaneously. The included 0.8m Thunderbolt 5 cable is certified for full performance; avoid using longer or uncertified cables as they may reduce bandwidth. If you manage multiple docks, take advantage of the firmware update via host feature to keep all units secure and up to date.
