I just found an odd thing. The Nvidia graphics drivers come with one of those little systray apps to allow you to fiddle with the settings. One of them, I just noticed, was ‘Rotation’. Indeed, as you might guess, you can rotate the screen through 90,180 or 270 degrees. I can just about think of reasons for this being useful (reflection arcade-console style, or a feature-lacking projector). I tried it just to see if it worked, and it did. It also popped up a box labelled ‘confirm display change’, just like it would with any other change. The fun part is that the box’s contents were something entirely different, not including OK or Cancel, but some slider to do with powersaving. Now, the display properties changes that you make normally time-out after 15 seconds, so you can’t blind yourself. I can now get rightside-up desktop for only 15 seconds at a time! What fun!
