How to reduce brightness

[vlada572]

I'm looking for a way to reduce brightness on lg 23mp68vq. I already set brightness to 0. Tried some programs that add black layer but it doesn't work properly. (sometimes taskbar is not dimmed and doesn't work in games)

The graphics card should also have its own settings to lower it more.
