Both the CRD and T14s support altmode for external DisplayPort over the
USB Type-C connectors. The CRD has 3 such connectors while the T14s has
only 2.

Enabling DP altmode requires the support for the Parade PS8830 USB Type-C
retimer. [1]

Currently, only the DP 4lanes and USB3 modes have been successfully
tested on both CRD and T14s. The DP 2lanes + USB3 mode seems to suggest
that changes are further needed in the QMP PHY driver.
