I'm working with/on a software that is optimized for screens in portrait mode and some of the features rely on this orientation, so things won't work or won't be displayed correctly with landscape orientation.
In the Windows 7 settings, I can rotate the screen content which works fine, but I'd have to physically rotate my screen to make this useful, which I unfortunately can't. Rotating my head isn't the most ergonomic solution either.
So a tool to rotate the screen content and display the result in portrait mode would be useful. Of course, there would be some scaling drawbacks involved as the vertical resolution is much smaller, but I could live with that.
Is there something like this? Of course, feel free to recommend alternative solutions.
