in prototyping my auto rotating monitor, I was rotating to the right. for a better viewing angle while vertical I have decided to rotate to the left. I have mame rotating fine and of course the horizontal layout is fine. However the vertical layout is upside down. I can't find where to flip it permanently, just momentarily in the main context menu. I must have looked at every tab in setup and everything in layout 3 times, and I'm just not seeing it.
can someone tell me where so I can say "DERP!" Thanks.
