SYMPTOMS

You experience the following issues on a computer that is running Windows Vista or Windows Server 2008.

Issue 1

Consider the following scenario:
  • The computer supports hot-plugging of Peripheral Component Interconnect (PCI) Express graphics devices.
  • On the computer, you install the driver for an external PCI Express hot-pluggable graphics device.
  • You hot-plug the graphics device into the computer through a PCI Express cable or by using another method.
In this scenario, the external graphics device is not recognized the first time that it is hot-plugged. Or, the driver for the external graphics device is not loaded as expected, and you receive the following error message:
Incompatible Display Adapter is being disabled

Issue 2

Consider the following scenario:
  • The computer supports hot-plugging of PCI Express graphics devices.
  • The computer has an external PCI Express hot-pluggable graphics device.
  • You connect multiple monitors to the computer.
  • You configure a monitor on the external PCI Express graphics device as the primary monitor.
  • You put the computer to sleep (S3) or into hibernation (S4).
  • While the computer is asleep or in hibernation, you hot-unplug the PCI Express graphics device.
  • You resume the computer from sleep or from hibernation.
In this scenario, you see a black screen. However, on a monitor that is connected to the internal graphics device, you expect to see either a logon dialog box or the desktop.

Note These issues occur even after you apply hotfix 956756 on the computer.
