Monitors are plug and play meaning you don't need a driver for it

However, if your talking about your video card drivers refer to

no video signal - video card broke down or screen resolution is to high
try boot in safe mode and un install de video card

You should google this. After looking myself i have seen that it should play HD movies without a problem.

This is more likely an issue with you video card than your monitor, do all the monitors you have tested operate at the same resolution and refresh rate? It sounds like the LG monitor is running at a higher resolution and refresh rate which is causing addition load to be placed on your video card causing it to crash

i have the same thing, monitor display is dark and tick tick sound audible and thats all it do untill now..

Your resolution or screen refresh rate sounds like it is too high.

Try dropping your resolution to 1024 x 768 and see if the issue persists.

If it does then perhaps your game is trying to force you into a higher resolution output and faster screen refresh rate than your graphics card or your screen can handle.

Assuming that the graphic output is fine when your not playing this game and just using windows?
