I have a Dell 2005FPW that I have connected to my PC via DVI. I like to use it with my powerbook when I'm at home as well and for convenience (not having the unplug the DVI from the PC) I've been using the VGA connecter with the DVI/VGA adapter that comes with the PB. I've noticed that there are faint vertical lines across the display when I do this. When I hit the auto-adjust button on the display the lines typically reappear in other places. I'm guessing this is an artifact of the signal conversion? Does anyone else see anything like this?
