I mainly use Windows 10 on my devices, which have lots of nifty features. One such feature is night light. I recently started using a USB docking station with DisplayLink support, which makes life much easier when switching between computers, but wanting to use the same accessories (monitors, keyboard, mice, speakers, etc.).
I was therefore disapointed that the night light feature was not working out of the box. A search showed me there is an article on the DisplayLink website that shows how to activate this feature also on DisplayLink displays.
Ensure you have a DisplayLink driver version of 9.0 or above. This can be checked in Device Manager in
Display Adaptors > [docking station] > Driver. I have version
10.0.82.0at this point in time.
Open Registry Editor and navigate to:
Note: I did not have the keys
Core. If these keys are missing, create them.
String valuewith the name
EnableGammaRampand the value
Unplug and re-plug the docking station.
Turn on night light.
If you wish to use a
.reg file instead, paste the following into an empty
.reg file and execute the file.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core] "EnableGammaRamp"="true"
