Just discovered: disabling Windows HD Color option returns this to proper f.lux color, i.e. virtually the same as the other 3 monitors.

@herf, Hello Herf and especially thank you for your link. I dug up the topic, because I did the procedure and unfortunately the DisplayLink folder doesn't seem to exist in my registry.
See the screenshots in on the link page:

Thank you in advance for your answer.

@tjerino yes I agree - we definitely have it planned for the website!

The original issue with the interface is that it is very hard to pick a whitepoint if there is not much white stuff on screen, so we have tried dark mode UIs a few times and not been able to sort it out. I will think again if we can do something better here.

@Kosake see our thread on displaylink adapters here, you may be able to fix it:

The power saves feature on your computer automatically switches off the monitor when the computer hasn't been used for a set period of time, saving energy bills and preventing a condition known as "screen burn" that can permanently damage the monitor display.

@TwoCables said in Flickers daily for a bit at 9pm sharp:

The actual fix is, disable Microsoft's Night Light feature in Windows 10. The flickering is caused by a conflict between Night Light and f.lux. Turning off Night Light is the solution. Anything else that solves it is just "a Band-Aid solution", and is therefore incorrect.

Hey all, reviving this thread for future f.lux users. I tried TwoCable's fix and it worked perfectly. Turn off Microsoft's Night Light feature in Windows 10/11. The night light feature effectively does a similar thing to flux (reduces blue light), and it turns on at a certain time every day. This is causing Flux to flicker at X:00pm sharp.

"Select Start, then enter settings in the search box. Select Settings > System > Display > Night light", then turn off Night light.

done and done.

Found the issue, f.lux had turned off Windows' dark mode but didn't turn it back on again when un-checking the option. Bug fix?

Install Autohotkey and use this code and run the script.

Scroll the mouse wheel up/down at the very top of your screen only to adjust brightness.
If you don't know how to use Autohotkey then msg me and I'll send you the .exe file

#NoEnv SetWorkingDir %A_ScriptDir% CoordMode, Mouse, Screen #SingleInstance, Force #If MouseIsOvertop() $~WheelDown:: send, !{PGDN} return $~WheelUp:: send, !{PGUP} return #If MouseIsOvertop() { MouseGetPos,,y Return y < A_ScreenHeight - 1070 }

thank you so much!!
