Abstract
A system and method for determining whether a target display subsystem is compliant with a reference display subsystem is provided. A target display subsystem is selected for outputting image data. Drawing instructions are generated and applied to the target display subsystem. Image data generated by the target display subsystem, responsive to the applied drawing instructions, is periodically captured and recorded. The reference subsystem is selected, and the same drawing instructions are applied to the reference display subsystem. Image data generated by the reference display subsystem is periodically captured and recorded from the reference display subsystem. Thereafter, the captured image data from the target display subsystem and the reference display subsystem are compared to determine whether the target display subsystem is compliant with the reference display subsystem.
