For all of these software packages, you should change the color temperature to the lowest possible usable value (1000K for redshift, 800K for f.lux).

For the purpose of DP management on Windows OS, '''SunsetScreen''' is the preferable choice over the widely more popular f.lux, as the latter does not allow setting user defined start and beginning times in conjunction and enforces a preset duration for the color shift, which will not be optimal for many schedules, to circumvent this, the user has to manually shift down the color temperature (by repeatedly pressing '''"Shift+Alt+Page Down"''' key), moreover, this custom setting is not stored and overwrites the automatic color shift timing, forcing the user to repeat the same procedure at least once per day.

Additionally, SunsetScreen allows setting predefined values for brightness for day and night setting separately and offers the option of toggling a color inversion mode by hotkey.

An alternative, potentially more effective, method of software based color filtering is employed by '''NegativeScreen'''.

It offers 12 different predefined color modification schemes, which tend to produce more usable and vastly more customizable results (it is possible to create custom inversion profiles with the help of a GUI application) than the more basic color inversion software like the integrated Windows color inversion mode. Of particular interest for the purpose of DP management is the "'''inverted red'''" mode, which drastically reduces the amount of visible light emitted by the display (especially when originally light colored content was presented on the screen), while having a similar color shifting effect to the other software presented above.
