bad DVI Cable = hosed dvi input?

[Double Jesus]

I have an LG 204wt that was hooked up to my 7800gt and the DVI cable broke on one end. The flat pin (blade) broke off the cable and was stuck in my video card's dvi port. I pulled it out as soon as I noticed and then stopped using the cable but now it seems that the DVI connection to my monitor doesn't want to work and now the output from my card is always greenish. Would this be the result of the cable being broken??? I'm going to try my monitor on another computer to see if that helps any... but the output from my card is definately always green no matter what monitor/cable i use. (i'm using a dvi-vga converter on it and the converter is definately ok as it works fine on the other dvi-out port).
