Are you seeing anything at all? The intended appearance is mostly red and black with a "photo negative" appearance, just like a photographer's darkroom.

I wonder if the location wasn't actually set in the first install? There should not be much difference after upgrading.

@johnedwa I understand that, but what's with the sudden drop even though I have the 60 minute slow change enabled? Or the weird dip during the day?

Are those simply the result of the whole thing "breaking down" like you said?

@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
