I'm using my wife's Macbook, and I just noticed that her screen is off axis, but I can't find a way to adjust it. I've tried playing around with resolution in preferences, but nothing.
Maybe a terminal command for adjusting the x and y values of the screen?
Any and all suggestions welcomed 
What does it mean to be "off axis"? Can you describe the problem in more detail?
It was intended to mean that the viewable area of the screen was not in the actual middle of the screen.
If we apply x and y values to a screen, we might imagine that coordinates 0,0 would be the center. The problem then was that the point 0,0 was where you might expect -10, 3 to be, for example.
