So was playing FF14 just fine last night on beta, this morning I boot it up, it goes full screen and I get a message "Input not supported" dancing around on my monitor in the same message box that usually comes up if you have a disconnected cord from the monitor or it can't pick up a display.
Any idea what would cause this? Other games function just fine, and my account works fine on my wifes PC which is only running a GT250 card.
I tried swapping around my 6870 cards since I had 2 of them, but both wont work.
