Why does Windows 7 recognize my second monitor yet the second monitor remains blank?

Why does Windows 7 recognize my second monitor yet the second monitor remains blank? I bought a new monitor (Acer X203H) and wanted to plug it into my graphics card but on my graphics card one plug says CRT which is already filled with the first monitor and the second says DVI, which I don't have a cable for on my second monitor.

"The issue is that you are using a video card, so the VGA port on your motherboard is disabled. I wouldn't expect the monitor plugged into the motherboard to be recognized even, but I suppose it's possible.

I'd recommending connecting to your monitor using the video card's DVI slot (the white port next to the VGA connection). If your monitor does not support DVI, you can plug a DVI -> VGA converter into the slot.

DVI usually provides a higher-quality connection, so you should plug your new monitor in the DVI slot if possible, and your older, CRT monitor, into the nearby VGA slot."
