Hi macbain, I too am trying to apply the flux filter to my Samsung TV using AirPlay however the flux settings are not carried over and the TV screen is bright enough to wake up the neighbors! Wondering if you may have found a way to wirelessly carry over the flux settings? Thank you for any thoughts you be be able to share. Steven

Hello. So sorry for not replying... Chronic migraines will do that to a person...

What is the "expand color range" menu item? Is it in the Options screen? It can't be the "expand slider ranges" check box. Under the color menu there are just special effect options...

Heres my driver info. I have an old Thinkpad W530, it has a wide gamut monitor. If I use certain color profiles with this monitor then when f.lux ramps down the color temperature then it seems to maintain the white point better, but at the trade off of not having as intense of color.

I have three profiles I am playing with, the best one with the deepest colors is the one that even on the Sunlight setting if I click the box to use the internal color table then I can see that the white point is moved way into the yellow...

Same behavior if you disable f.lux for a specific app disables f.lux across all monitors now :(

@moomoolan we do have a feature for this and it's only available via a hotkey: windows+End will toggle it on or off. Possible to do accidentally?

@ersanzop
how to resolve it.? . .

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.

@CTS_AE please post f.lux options > driver info here. Usually f.lux uses its "fallback" mode due to a lack of driver support, such as with a USB adapter.

I have two monitors. One is on DVI mode - one is on DisplayPort mode. My monitors go to sleep after 1 minute of idle time. But when I use the mouse to wake it back up, the DVI mode doesn't always go back into Flux mode, instead hitting full blast blue light and all those melatonin-shattering shenanigans.

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

@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?
