VGA connector is blue and a DVI connector is white. Which connector do you have on your monitor? Im assuming you have DVI (white) on your gfx card right? Which connector does your cable have?
I have 2 white connectors (I assume it's DVI, the holes are a grid of holes, 3x8, and then next to it is a +-shaped hole with another 4 regular holes altogether in the space between the prongs of the +) that are both the same. I have 2 connectors I can use on my monitor, one, is a white connector that has to sets of 3x3 pins, and then a - shaped pin on their left. The other one is blue and it has 3 rows, 1 and 3 are in line, then row 2 is staggered so it's between, so it looks like this:

EDIT: Dangit, the layout of the dots didn't work in the actual post. it looks like that, but with the middle row staggered to the right a bit so each hole is between the space of the holes on the two sides of the 1st and last rows, and the last one is just outside on the right
