every time i start my computer, it automatically detects and connects a 2nd monitor that is not attached. it even does this when i have the "use manual detection only" option ticked in AMD vision control center. the monitor it detects says "analog, CRT, 1024x768". every day i have to open the control center and disable the 2nd monitor, only to have it reappear if i restart.
for some background, i'm running windows 8, my graphics card is a MSI 5870 Lightning II. it has never had a second monitor attached. i have the most recent updates for both windows and the graphics driver. i don't know for sure if this happened in windows 7, but i don't recall it doing so.
