It may not be a bug with the Intel driver but the hardware. I have
seen several PCs show 2 monitors when the driver is told their is only
one. As long as the there is not a problem with the hardware
(yellow !) you can / should just ignore this. If yoy remove the
"repeated" monitor, XP will re-install it.
