On the other hand, you have the possibility to adjust the screen lighting and colors manually, which is convenient in case you are in an environment with special lighting conditions. Therefore, if you find that you are not satisfied with the settings, you can go back and make more adjustments. It is worth mentioning that f.lux enables you to preview an entire day’s lighting changes in just a few seconds. Automatically adjusts the screen brightness and tone It then renders the appropriate light tones and intensity depending on this schedule. In other words, once your position is set on the map, the application calculates the precise time of the day and puts your PC on a 24-hour transition schedule. The main perk of f.lux is that once set up, it can automatically adjust the screen's brightness and color to the night or day conditions, without your intervention.Īt first launch, it requires you to enter your current location (the nearest city will do) to determine your local time and get information about the lighting conditions, depending on the time of the sunset and the sunrise.

To see what this might mean, click the blob representing the sun in the program's Settings dialog for a quick preview it'll be at normal brightness levels during the day, but change to warmer, more orange/ yellow glow at night.Ĭlick "Change Settings" and you can further customise the program to better suit your needs, by more accurately setting your location and deciding how quickly you want the colour temperature change to occur (it's annoyingly fast by default, but setting to "Slow" here will help).Īnd you can also adjust the colour temperature you'd prefer at day and night, but unless you're extremely sure what you're doing we'd recommend you try out the defaults for a while, first. To avoid all this, F.lux uses your location, the date and time of day to figure out your sunrise and sunset times, then automatically adjusts your monitor's colour temperature to a more appropriate level.
