Why does it think I have a second monitor?
I have a Power Computing Power Tower 180.. I installed a PCI Video Card, but the Mac OS still thinks I have something connected to the old monitor. Is there any way to kill the internal video?

If the old monitor was connected to a PCI video card, you'll need to remove the other video card. I'm not sure about PowerComputing, but most Macs that have a built-in video port will disable the built-in automatically if you use a PCI card and only one monitor. I've got a PowerTower at work, and I'll check it when I go in this evening.

Also, if you have a Mac-VGA converter still attached to the old video connector it will be "fooled" into thinking there's a monitor there.

It appears, upon inspecting a PowerTower, that the "built-in" video is actually a PCI card. If you upgraded to a new card to replace the old one, then just remove the old card.

The the PowerTower 180s are built anything like the PowerCenter Pro line, you can't do that. The circuitry, though PCI based, is for all practical purposes integrated as it sits on a riser card which contains connectors for the other PCI slots.
