@james_s We've been giving f.lux away since 2008 for free. Some of the comments we get from users make it all worthwhile. I regret to say that your comment doesn't fall into that category.
Nevertheless I appreciate you took the time to write to us. Future versions of f.lux will be more customizable, and I hope you'll try it again in the future. For now, there are plenty of clones (even built into the OS) who offer manual timers, and hopefully one of them will offer the features that you are looking for.

"Translating it into Chinese"? That's what I could help with. I am a professional mandarin language translator working with a team of fellow translators/localizers. Will see what we could take part in...
Forgot to say that I am also running a language team dedicated in Chinese mandarin translation. Visit our team website at:

SOLUTION! I got this sorted! I am using MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports). I was using a docking station that is connected via USB and then HDMI cable from the docking station to my external monitor. When I started using USB-C to HDMI adapter and then HDMI cable from this adapter to my monitor, it worked. Enjoy!
I guess everyone knows it but those who use Windows 10 have a built in option that does the same as f.lux. It can be fount in settings -> display -> night light.
I have been using it for a long time and it works fine.
