Turn off "Night light" in Windows. It's in Settings > System > Display. You'll find it at the very top.

Interesting stuff, I didn't know that. I can't find my laptop's lcd profile on the database, I will check QuickGamma for sure.
Thank you.

Sorry herf, I though that i'llreceive an email for answers...
So i look at driver info on tuesday because I'm not near the concern computer.
thank'you very much !

There is a detail view with three sliders, so you can adjust all the parts of the schedule at once.

But my recommendation is that you should reinstall just in case the resource files became corrupted.

Hi, this is not our doing - do you have any other software trying to change color settings?

Hey, could you help me to set them out?

Interesting question here.
I actually have set my wake time as 3 hours earlier than my actual wake time, as I want my computer to dim earlier than the software allows.
I was listening to a Podcast episode with Dr Rhonda Patrick, and her sleep expert guest - and suggestion was to start reducing light/ wearing blocker glasses/ sun glasses from 5pm if you are sleeping at 11pm.
So I was hoping for a "red" screen from 8pm or so.... or even earlier... at dusk ideally...

Basically I agree with the ability to be more flexible...

Did you find a solution to this? I'm having the exact same issue
