Thank you for contacting Plugable support! I’d be more than happy to assist you.
Native Thunderbolt and USB-C devices like the TBT3-UDZ and USBC-HDMI will handle color calibration without issue. Color calibration is only not possible for docks/adapters that are not using the system graphics chipset (like other DisplayLink or Silicon Motion based USB graphics adapters and docks we offer).
So for your TBT3-UDZ dock it will support color calibration as the displays attached through this dock are ultimately being driven directly from the graphics chipset in your computer and the dock is not DisplayLink/Silicon Motion based. The USBC-HDMI adapter will also support color calibration as it’s just converting the USB-C DisplayPort video signal to HDMI, but is also driven by the graphics chipset in your computer.
When using a color calibration device (like the SpyderX) it will not know that your displays are not directly attached to the system and it will calibrate them as expected. So you should be good to go with the equipment that you have.
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
