Recently, all display has completely vanished from my monitor, however it still comes off standby when I turn on the PC.
I was told that this could be the graphics card, so I bought and installed a brand new one, however that doesn't seem to have worked. It can't be the cable or monitor because I have tried hooking them up to a friends laptop and it works absolutely fine.
You can only really plug it in one way and to one connection so if it fits it should be ok. The clue is that it is the same as with the other card so i would try and connect another monitor up to see if it's that.
