Knowledge sharing: FIXED Brightness setting on DisplayLink monitors
I would like to share with you the solution to a problem I have been facing for a long time, and it made me extremely unhappy :)
I like to use the f.lux feature where I use keyboard shortcuts to change the brightness of the screen using ALT+PGUP, ALT+PGDOWN.
About half a year ago it stopped working for me, and today I finally found out a solution.
- Lenovo laptop T14s
- USB-C Docking station
- 2x Dell 27" QHD Monitor connected using display port to docking station
So what you need:
Latest displaylink drivers
Run Registry editor as administrator.
Create a new key of type string with name "EnableGammaRamp" and value "true".
Disconnect the USB-C docking station from the PC, wait a few seconds and reconnect
I've also re-run f.lux application.
That's all :)
ALT+PGUP, ALT+PGDOWN is working again.
Live long and prosper.
