shouldn't matter. At least with my 6800GT my monitor will display the image no matter which port I plug it into. But still worth a try.
But trying another vid card would be a good idea. I doubt it's the adapters, since it's very unlikely that both of them are messed up. Though again, you could always try an adapter that has been tested and is working fine.
I had the same kind of problem when building this pc, turns out my mobo was busted.
