Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: Graphic Adapter or Chipset Testing Prerequisites.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting Device.Graphics Testing.

More information

For an N-bit-per-component RGB frame buffer format, the lowest N bits must contain the blue component, the next N bits must contain the green component, the next N bits must contain the red component, and the remaining 32-(3 x N) bits may contain alpha. The resulting 32-bit value must be stored in memory in little-endian format.

Note

   This requirement is "If-Implemented" for Windows Server.
