For using the tablet in a dark room, I am trying to set my screen dimmer than the lowest brightness setting that windows provides. Just like you would use screen filter in Android devices.
So far I have only found 2 portable apps that does this:
However, while they do dim the screen, it only dims the normal desktop applications. Once I switched to Metro interface, the screen still shows as its normal brightness.
Is there a way to dim the metro interface screen brightness dimmer than the windows lowest brightness setting?
