Since a few days, my screen goes black after a few minutes of inactivity. My PC isn't going in stand-by, nor is the screen. As soon as I move my mouse or press a key on my keyboard, it just goes back to normal.
I have checked W7's power management, the screen itself and my graphics card. Nothing is wrong with them.
Any idea what could cause this and how to solve it?
The screen is an LG Flatron W2361V.
