I have a Targus docking station and luckily it used DisplayLink, the key does not exist with the Targus drivers installed so…
- Go to https://www.displaylink.com/downloads/windows and download the DisplayLink drivers.
- Install them.
- Start RegEdit
- Navigate to
- Create new String value with name
EnableGammaRampand set the data to be:
- Unplug and plug your DisplayLink device
- Enable Night light in Windows
All your monitors should now be at the same gamma settings.
