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.
