I'm a bit tired of setting my screen contrast and brightness manually for each screen every morning and evening, so I'm looking for a way to automate this.
I'm already using F.lux and it's great, but it only changes color temperature. In the night, I still find my screens too bright. Recently I found Screenbright which does exactly what I want, that is, changes hardware brightness and contrast, and works from the command line as well.
Now I'm off to automate this. Is there a way to set Windows task scheduler to trigger task on every sunset and sunrise? I can set it to a fixed time every morning/evening, but that's not as elegant as I want it to be.
1No, you would need a program which has the algorithm to calculate the sunrise and sunset times and then you could use those times to set scheduled events for the next 9069 days. – Dan D. – 2013-03-04T00:07:26.543
That's not enough- sunrise/set times don't take into consideration the direction the OP's window faces, or if it will be overcast or sunny on any given day. Without an ambient light sensor this is going to be a source of constant frustration. There are far too many variables to accurately predict the brightness in the room based on information from the internet. – Austin ''Danger'' Powers – 2013-03-04T00:57:58.940
Instead of changing brightness & contrast settings, inverting screen colors achieves almost an instant 90% drop in brightness. (wiki/Light-on-dark color scheme). And Windows Magnifier is all you need.
