Getting Night Light to work with a docking station in Windows 10

This comes from How to enable Night Light feature on DisplayLink devices in Windows 10.

I have a Targus docking station and luckily it used DisplayLink, the key does not exist with the Targus drivers installed so…

1. Go to https://www.displaylink.com/downloads/windows and download the DisplayLink drivers.
2. Install them.
3. Start RegEdit
4. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core
5. Create new String value with name EnableGammaRamp and set the data to be: true
6. Unplug and plug your DisplayLink device
7. Enable Night light in Windows

All your monitors should now be at the same gamma settings.
