VPE and Kernel Tests
This automated test performs a variety of subtests. These subtests include video-port flipping, scan-line and vertical-blank synchronization, and bandwidth and pixel format reporting.
If the video driver claims to support video port extensions (VPE) via the DDCAPS_VPE option, DVD and/or analog capture hardware must be available for the test. The analog decoder must have a valid video signal, and the DVD player should have a disc loaded.
The complete list of subtests is as follows:
KERNEL_ReleaseKernelHandle
KERNEL_GetKernelHandle
VPE_UpdateVideo
VPE_GetVideoPortConnectInfo
VPE_StopVideo
VPE_StartVideo
VPE_CreateVideoPort
VPE_QueryVideoPortStatus
VPE_GetFieldPolarity
VPE_GetVideoSignalStatus
VPE_SetTargetSurface
VPE_Flip
VPE_WaitForSync
VPE_GetBandwidthInfo
VPE_GetInput/OutputFormats

Running the test
Before you run the test, complete the test setup as described in the test requirements: Graphic Adapter or Chipset Testing Prerequisites.
In addition, this test requires the following software and hardware:
Microsoft® DirectX® 7.0 or later versions
Video card with Microsoft DirectDraw capabilities
Troubleshooting
For troubleshooting information, see Troubleshooting Device.Graphics Testing.
Turn off the screen saver and disable power management before you run this test. Mode changes and full-screen applications can cause failures. Therefore, you should avoid them.
More information
Most of the DirectDraw tests (including the Blt - Exotic test) are in Fnddraw.exe. You can run Fnddraw.exe outside the Windows HCK, and then select initial tests. On the Tests menu, click Select Tests.
The test titles that are listed in the HCK do not directly match the test names in Fnddraw.exe. In fact, the names in the DCT often refer to a group of Fnddraw tests. You can obtain the Fnddraw test names from the HCK log file.
You can pause many Fnddraw tests (especially Blt-related tests) to give you time to visually analyze the Blt results. Use the Pause key to pause and resume.
Use the Esc key to stop a test run. Be patient, because some tests are stop more quickly than others.

| Command option | Description |
