I've been running dual monitors at home for years with no problems. My problem here is at work: I have a laptop and a 17" LCD. When I first connected the LCD, it defaulted to using that one as my "primary monitor." That was no problem, because it was bigger than my laptop screen and I liked using it as the primary. A few weeks later, I went to give a presentation and connect my laptop to a projector. The projector worked just fine as a second monitor, but when you do a "view slideshow" in PowerPoint, it will only display on the primary monitor. So no matter what, the slideshow would appear on my laptop, but not on the projector. The option in setup to "use this device as my primary monitor" was greyed out. Now I'm back at my desk, and I reconnected the LCD monitor to my laptop, and it's forcing it to be the secondary monitor again. So my question is, how do I force a certain monitor to be primary? I know it's possible, I just can't figure it out.
