I frequently move my desktop from my dorm room to my home. I have a 19" LCD (DVI) in my dorm and a 21" CRT (D-sub) at home. When I leave the dorm, all I do is shut off the computer w/out changing any settings. When I get home, I plug everything in, and the monitor never detects anything, I start the computer and the monitor just proceeds to suspend mode. Only after numerous restarts does the monitor all of a sudden detect a signal and I get post. This same thing happens whenever I'm changing monitors (even when going from D-Sub to D-Sub), is there something I'm doing wrong?
