With most monitors that rotate, they come with a piece of software for Windows that automatically adjusts the image so that the menu bar is at the top of the screen, etc. (Basically so you aren't looking at a sideways image)
Usually, it automatically does this. My monitor doesn't come with Mac software to do this, only Windows, and I wanted to know if OS X automatically did this without any extra software.
& to Unity, I've seen the rotation preference but I wanted to know if you could have it automatically rotate the image when the screen was rotated 90 degrees.
Thanks
