It is better to know where the problem lies before proceeding with other solutions. If the fault lies in the monitor it would be a waste to go through the hassle.

Graphics card issues

If your PC has a dedicated graphics card, this may be the cause of the black screen. Check to make sure that the graphics card is properly seated in its slot and that its power cables are connected.
