Hi everyone!

A few weeks ago my laptop (benq joybook r56 ) went wrong, and I decided to save its monitor. I suppose I could use it as an external display, or a secondary monitor for my pc.
As I know this controller board can be connected to the monitor:

laptop monitor:

But where to connect the 3 additional cables (black white and grey)? These can be connected to the controller board or I have to use an external power supply for it? In this case wich cable is the ground and what voltage sould I use?
