Brightness Control

I already stumbled over this thread that says brightness should be controlled by the TV. The problem is that I use my PC monitor and controlling brightness without a remote control is tedious. Therefore I would highly appreciate having the option to control brightness. There should at least be a way to enable brightness control again. As far as I've been reading all of this has been existing for years.

Okay, stupid me. How in the world is the Raspberry Pi going to control the Backlight of my monitor? It is impossible unless there is an interface for it. Changing the contrast and brightness in software is not going to be satisfying.
