I had already looked in display driver, nvidea control panel, tried the ctrl+alt+arrow etc, and nothing works. so i would have mame the right way up, and windows upside down, which given I would need to do stuff on would be a pain.
I was thinking this community might know of other ways if this was more common than among the common public who rarely need an upside down screen.
glad to hear it does happen, however seems like I will have to upgrade to windows 7 rather than buy an IPS. everything bar the artwork is going to be recycled materials...
