Windows 7: Ghost monitor left in control panel after testing three monitors

Ghost monitor left in control panel after testing three monitors

I have 2xSapphire Radeon 6750 1GB DDR5linked with a Crossfire cable.
More accurately, this card

Normally I have only two monitors connected, one on HDMI and one on DVI.
Yesterday I brought home a third monitor just to test around a bit, to see if I could get a third monitor working. I had the cables so I tried connecting it to either DisplayPort, HDMI or DVI on either of the cards, alternating. So far I have failed. This is not really a big surprise since I got info from Sapphire telling me it would most likely not work, since the cards do not support multiple monitors beyond two.

The most surprising part was Windows. It tried to detect the third monitor as connected via VGA and extend desktop to it. I went along and played with the settings a bit to no avail. The third monitor (an older Eizo) does not have a VGA port.

So I disconnected it, rebooted just in case, and left the matter for another day.

To my surprise, Windows still claims there is a VGA monitor, diconnected, but it is there.

My display settings:

And the "ghost" display setting:

How do I remove this last entry of a monitor that is no longer connected??
