Hello, I have spent some time seaching for the answer to no avail. I have a HIS Radeon 6870HD graghics card and an old dell monitor that has been functioning just fine until I found my computer in this state today after my wife powered up the computer this morning. I have tried to use the monitors shift to the left to get the screen centered to. It doesn't go far enough. Everything is there but just offset. Any ideas as to what is happening and how I get it back to the way it should be?
