So for some reason mid way through a Skype call, my monitor developed an issue with several blue dots climbing up the screen in vertical lines. As this was a cheap monitor from a charity shop, I wasn't expecting the earth. I think I may have had it 2 months absolute tops. I have tried unplugging and reconnecting the vga lead, at both monitor and PC end. It is going through a DVI adapter,but I personally doubt it could be that, but I'll check it later. Picture (hopefully) attached to show you what I mean.
