Products Affected:   Thunderbolt Station 3 Lite [TS3 Lite], Thunderbolt Station 3 [TS3]

Customers using the 2 meter long CalDigit Thunderbolt 3 Active cable with non-CalDigit Thunderbolt devices may experience issues with their connected displays flickering after extended use. This is due to a vast and diverse Thunderbolt 3 hardware landscape which makes it difficult to account for every hardware variation present in the different Thunderbolt 3 devices currently on the market. As a result we have discovered that the CalDigit 2 meter Thunderbolt 3 Active cable may run into certain video issues with non-Caldigit Thunderbolt 3 products.

For instance, when using the CalDigit Thunderbolt 3 Active cable with a Lenovo's Thunderbolt 3 dock, users may notice that the video on their connected display(s) blink on and off after extended use. This is due to an inherent hardware difference between the 2 meter CalDigit Thunderbolt 3 Active cable and the Lenovo dock’s handling of video streams. In this case, please contact your Thunderbolt 3 device vendor to verify if your device is capable of using 2M cable. Some devices may only be able to connect with 1 meter or less than 1 meter cable. Some devices may also require video firmware update from time to time. Please check with your device vendor.

This issue is NOT present when the 2 meter CalDigit Thunderbolt 3 cable is used with any of CalDigit Thunderbolt 3 hardware including the TS3 and TS3 Lite docking stations.
