DVI Black Screen Problem ( read first )

[Miroslav2]

Ive always used a HDMI on my monitors until I bought a ps4 recently which can only be connected to e monitor vie HDMI and my monitor only has 1 HDMI port so I now use a DVI cable to establish a connection between my PC and monitor .

Well , many times when I lock my PC and I come back after a few minutes when the screen has gone dark and try to resume it , I just black screen and nothing . If I connect a HDMI to my GPU to the monitor , the screen goes back to normal , as well as if i connect a HDMI to my motherboard , the scree goes back to functioning as well. If I unscrew and unplug the cable from my PC and plug it back in , it sometimes fixes it or sometimes when I unplug it from my monitor , that fixes it.

So , this can eaither be a faulty DVI cable , faulty DVI ports on either my PC or monitor and a compatibility issue with my GPUs drivers , which one do you specialists think is most likely to be .

• ■Remove the DVI cable, connect the end that was connected to the video card, to the monitor.
  ■If you have another DVI monitor, try it.
  ■Try to use a different DVI cable. Buy or borrow one if need be.
  ■Open the case, and make sure the video card is firmly seated in its slot. Remove it, and reseat it.
  ■Make sure the power cable(s) connected to the card are firmly inserted into there socket.
  ■If the power supply is modular, make sure that the end of the power cable at the power supply is also firmly inserted.
  ■Move the monitor to another computer that has a DVI port, and see what it does there.

If the monitor works on another computer, then its likely the video card, but I would still want to try the video card on another machine to see what it does in the other machine. Why? Because while the odds are very, very low, this could somehow be a motherboard problem, and checking the video card on another machine would answer the question of which was faulty.
