@crazydef After some tests, for 10.50E, 55.30N is max you can set without curve being broken. So, it breaks only far from equator ;)
Also, hello from 59.9 N :)

Turn off Microsoft Night Light.

Can confirm this morning all working OK with 3 screens and F.lux 4.74!

Only 25 GDI Objects in use! Thanks!

4.74 seems to have fixed the problem with crashes when connected to Displaylink. Great! Thanks!

Worth noting - checking and unchecking "Use display data for better color accuracy" in the options menu provides only a negligible difference for me, and is not the source of the difference.

@herf

Thanks. The issues in this thread seems to be resolved.

I am seeing some differences in color accuracy between v3 and v4, which I will note in a separate thread.

Is there a changelog to view the updates for each version? I'd like to pick one that works for me and stick with it.

Thanks

GASP! How did I never know about Alt+pgdn?! Thank you!

Now, If you could get the flickering to stop, that would be wonderful! BTW, I love using f.lux, it's an amazing tool to have while using a computer.

Do you happen to know what your DPI (screen scaling) setting is? I wonder if our sliders have a bug for some case we haven't tested.

We shipped a bug with DisplayLink monitors (USB) - if this sounds like it could have affected you please download again at https://justgetflux.com/

Our older installer (about 6 months ago) had a case where it wouldn't uninstall entirely, but we have fixed it in the newer versions.

So if you want to uninstall completely the easiest thing to do is download a current version and immediately uninstall it. (Easier than step-by-step instructions.)

Turn off Backwards Alarm Clock.

Flux added a new hot key feature in January 15 2018 to do exactly this request. Alt + Shift + End THANK YOU SO MUCH FLUX! I only found it today while reading the update notes. This just made my day!

Can you post the driver info (Options menu) also?

Yep, Alt+F12 is the alternative to Alt+Page Down, and Alt+F11 is the alternative to Alt+Page Up.
