What software is used to pivot the screen?
The pivot software requires you to manually check out the orientation, unfortunately there is nothing to sense how you are looking at the screen. The Silicon Motion has drivers for 9X, ME, 2K, XP and Linux on their web page http://www.siliconmotion.com/eng/pageHub.html?band=highband&url=accept.html&title=Support) PivotPro is a general application that works with many display’s including Viewsonic.
