Windows 10 Creators Update comes with a cool new feature called “Night Light“. It allows you to warmer the colors of your monitors during dark hours (or in a dark room) so your eyes feel more comfortable (programmers will appreciate it much!). It supportsf.lux‘s basic functionallity, but now it is a built in Windows 10 feature. Great!
But it does not work with DisplayLink devices due to some software limitations. Here is a picture of Notepad’s window that is positioned between two monitors (the right is connected via DisplayLink device):
As of driver version 8.2 there is a way to enable “Night Light” on these devices via the registry:
- Update your DisplayLink with latest drivers
- Start RegEdit
- Navigate toHKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core
- Create new “String value” with nameEnableGammaRamp and set the data to be: true
- Unplug and plug your DisplayLink device
- Enable “Night light”
It should be working now:
Personally I prefer to use Night light because of issues with f.lux (flickering, screen captures looks warmed etc.). Hopefully Microsoft will add a keyboard shortcut to enable/disable Night light mode easily.
