Screen looks greenish
I recently installed a 4850 hd. But when I tried to plug the screen into it, it looked okay for a moment and then started looking greenish, as if it lacked the color red. I tried to force it so it would make better contact, but I only managed to break one of the pins of the cable. So I got another cable and tried to plug it, but now the screen still looks as green as ever, no matter how I plug it. It also can't be the screen, because the menus of it show the red perfectly. I looked at the plug of the card and I seem to have poked a small hole into it by forcing it. What can I do?
