A WHQL test does not finish successfully on a Windows Vista-based computer that has multiple display adapters in an LDA configuration

Consider the following scenario:

  • You are running a Windows Vista-based computer that has multiple display adapters in a Linked Display Adapter (LDA) configuration.
  • You use the Driver Test Manager tool on the computer to run a Windows Hardware Quality Lab (WHQL) test that includes a Logo stress subtest.

In this scenario, the Logo stress subtest triggers a Windows Display Driver Model (WDDM) aperture corruption. Therefore, the WHQL test does not finish successfully.

There is a download that resolves this issue. See Hotfixes for details.
