Just out of curiosity: What do you use a three-monitor setup for? Uber-mega-jumbo productivity, I suppose. Gaming? Graphic design?
Stictly business. The XLS' that we use are 2-4 MB and rather than continous panning back and forth on 1 monitor I stretch it over 2. The 3rd monitor I then have Outlook.
We are slowly migrating to Win 7 but have some legacy apps that need to run under XP.
That's why my question stands as to what resolutions are available under XP Mode.
