To me, is something like this. Main Monitor vs 2nd monitor, connected directly to the same Graphic Card without any extra hardware: [image: Sem Título.jpg]

@herf Thank you.

Dear @herf, I think it's an emergency that you implement as soon as possible the option to simply turn on Grayscale at a given time and to turn it off at a given time. Anything fancier can come late, but people are literally dying from tech addiction, and it's high time f.lux evolves to help people use tech less than simply helping people go to sleep.

I have tried to set the key HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core\EnableGammaRamp = true, but that disables f.lux from working on the external monitoring completely.

@saimon yes you should turn off the f.lux setting that switches and use your system preferences to do it instead. We are built on top of those settings.
