My monitor is quite old and so I'm using a VGA connector, of which there doesn't seem to be a similar fitting one on my motherboard :S
Thanks guys, I'll try and search for a different cable and get back to you.
Edit: VGA connector as opposed to DVI-D. The only ports on my monitor are VGA and DVI-D.
I don't have a VGA to DVI-D connector and so can't currently connect my monitor to the graphics card, instead of the motherboard.
Any other solutions? Thanks for your help so far.
