F.lux brightness
-
I know you can decrease brightness using keyboard shortcut Alt+PgDn, but is this a white point value adjustment or simply an overlay?
I am trying to compare it to software like Iris Tech, which claims to control brightness with a different hardware-based method altogether: “At the end of the graphics pipeline, just where the image leaves the computer to make its journey along the monitor cable, there is a small piece of hardware that can transform pixel values on the fly. This hardware typically uses a lookup table to transform the pixels. Iris controls this hardware and uses it to decrease your brightness. You get flicker free low brightness”
My goal is to be able to decrease brightness without introducing/increasing PWM flickering.

@karahbit yes we have been saying this since a few years before Iris existed, though it sounds like our marketing isn't as good!
With a majority of LED backlights today showing essentially no flicker when they dim (see https://www.notebookcheck.net/PWM-Ranking-Notebooks-Smartphones-and-Tablets-with-PWM.163979.0.html), we don't think this is for everyone, as it has an impact on contrast and power usage. But with a display with bad flicker, it's absolutely a good way to do it.
