If you set your display to 4K@60Hz and connect a display to the DisplayPort output on the laptop docking station, your display may flicker. This issue only affects certain monitors and is a result of an interoperability issue between the hardware used in the display and the docking station. This issue is not specific to StarTech.com docking stations.
To resolve this issue, try any of the following:
Connect a USB-C to DisplayPort cable from the USB-C Thunderbolt 3 port on the docking station to the DisplayPort input on the display. (StarTech.com product ID for the USB-C to DisplayPort cable: CDP2DPMM1MB.)
Connect a USB-C to HDMI 2.0 cable from the USB-C Thunderbolt 3 port on the docking station to the HDMI input on the display. (StarTech.com product ID for the USB-C to HDMI 2.0 cable: CDP2HD4K60.)
If you are using a dual monitor setup, connect a dual DisplayPort adapter from the USB-C Thunderbolt 3 port on the docking station to the DisplayPort input on the displays. (StarTech.com product ID for the Thunderbolt 3 dual DisplayPort adapter: TB32DP2.)
Disable MST (Multi Stream Transport) or DisplayPort 1.2 mode on your display and enable 4K@30Hz. Refer to the information provided by the manufacturer for assistance.
