I purchased a 19" Samsung 930B monitor tonight just before leaving for church. I had just enough time to plug it in. I tried one setting in the display properties to try to get it to come on, but no luck and I was out of time. When I got back home, I found that it had sorted itself out, and both monitors were on. All I had to do was swap the primary and secondary monitors so that the new, bigger monitor would be the primary. I'm really going to enjoy the additional desktop space, but I think the most useful thing for is going to be the fact that I'll be able to use one screen for RDP (remoting into my work machine) and the other for my local machine. Pretty exciting stuff.
BTW, I signed the contracts for showtimemaps.com last week, so real-time data should be available within days!
