we recently purchased a new W2K Terminal Server. naturally, i wanted three displays. so i uninstalled the cheap ATI AGP video card and installed a maxtor dual-head card. at the next boot, both displays worked perfectly. the problem is when i installed a single PCI ATI video card. the system recognized the card and the device manager showed the card to be working but, when you go into the display icon in control panel and click on the setings tab, the single card monitor is not visible. when you click on the drop down arrow in display, the matrox card is the only option. i'm at a loss as to the problem.
