hmmm....I wonder if I have a similar problem. Most of your conversation was way over my head, but I'l like to post my problem anyway to see if someone can help. I have a compact pressario notebook...2100 series. I want to use the notebook like a desk top when at home. We have a wireless keyboard and mouse....just got a lcd tv monitor. Instructions state to plug in vga cable to both pc and monitor and it should work...WRONG. As I power on the PC..when I see the blue compact screen, but before the log on and music...the lcd monitor displays the same blue picture....then seconds later right when the pc asks for my log in, the lcd monitor goes blank/black....and a message states "no signal detected". I have no idea what to do. Any suggestions in simple terms?
