Emerald City only working on main monitor?

Peppy

Hello,

Been using f.lux for years for regular night time usage but due to studies showing green light helps with migraine pain, been looking around for programs that do a green tint to screens to see if the effect helps there too.

I found the Emerald City effect with f.lux but for some reason it is only being applied to the main monitor and not my second and third monitors. I see when I active it that the other 2 monitors start to get a green tint and then stop and go back to daylight/white light.

Note that the regular dimming for night time and giving red/orange tint works fine for all monitors, so is something odd with just Emerald City effect.

Side note, as mentioned at first, there has been research showing that green light helps migraines. If tinting does offer some of the same benefits as direct green light, it may be a good idea to have it made clearer that this option is for green light and maybe even mention something about migraine relief from green light.

@Peppy it should work the same on all displays. If you'd like to post f.lux options > driver info we can take a look at the details
