I am using a regular external monitor with a PC and would like to be able to adjust the brightness of the monitor according to daytime automatically.

So, in the morning it should start a bit darker and gradually get brighter towards midday. And in the evening it should slowly get a bit darker towards night.

How can this be achieved?


I found this one called iris, but don't know if it works with multiple screens and the worst part that it's not free. Below is a 7 day trial. https://www.softpedia.com/get/Desktop-Enhancements/Other-Desktop-Enhancements/Iris-Pro.shtml#download


I'm using f.lux now and am very happy with it :)
