Tips

To achieve 8K resolution, ensure your laptop's Thunderbolt 5 port supports DisplayPort 2.1 and use a certified 8K cable. For dual 4K @ 120Hz, connect displays to both DisplayPort outputs or one DisplayPort and HDMI. The dock's 140W power delivery is sufficient for most high-performance laptops, but check your laptop's power requirements if it demands more than 140W. When daisy-chaining Thunderbolt devices, connect them to the downstream Thunderbolt 5 port for optimal bandwidth.
