OPM_GET_ACTUAL_OUTPUT_FORMAT

Returns a description of the video signal that is being transmitted over the connector.

Requirement Value
Request GUID OPM_GET_ACTUAL_OUTPUT_FORMAT
Input data None
Return data An OPM_ACTUAL_OUTPUT_FORMAT structure

 

Remarks

The video signal that is transmitted over the connector does not necessarily have the same format as the desktop display mode. For example, the desktop display mode might be 1024 x 768 pixels at 85 Hz, while the connector might be an S-Video connector that transmits a video signal at 720 x 480 pixels, 60/1.01 Hz interlaced. In that case, the driver would return the resolution of the S-Video signal, not the desktop resolution.

This query is equivalent to the DXVA_COPPQueryDisplayData query used in Certified Output Protection Protocol (COPP).
