Why Doesn't the "Display Color Calibration" Tool in Windows Affect the Display(s) Attached to My DisplayLink-Based Docking Station/Video Adapter?

The "Display Color Calibration" tool in Windows is designed to adjust the color output of the primary display (the monitor connected directly to your computer's GPU). It uses the graphics card's capabilities to modify the color settings.

However, when you connect a display to your computer through a DisplayLink-based docking station or video adapter, the graphics processing for that display is handled by the DisplayLink chipset rather than your computer's GPU. DisplayLink technology compresses and transmits the display information over USB or Ethernet, which allows for convenient multi-monitor setups but bypasses the native graphics capabilities of your computer's GPU.

As a result, the "Display Color Calibration" tool doesn't have direct access to the color settings of monitors connected via DisplayLink. It can only affect displays connected directly to your GPU. To adjust the color settings of displays connected via DisplayLink, you may need to rely on the color adjustment options available on the monitors themselves.
