Old vidya' card

One of my old computers' runs Linux Ubuntu, but with an annoying shade of blue caused by the physical output1 port being damaged. Is there a way for me to force the output to the second port so I can get around this?

maybe this'll help oops no that's only sound, I try and find something else ;)
