A system for packetizing parallel image data for serial transmission includes a software element configured to receive a bitmap image file comprising R, G and B pixel data, receive information relating to display and timing information associated with a device under test, receive a vertical synchronization signal, and receive at least one horizontal synchronization signal, packetize the vertical synchronization signal, wait a period of time before packetizing the horizontal synchronization signal, and packetize the R, G, and B pixel data associated with the bitmap image file to form a parallel packet stream. The system also includes a hardware element comprising a parallel data sequencer comprising a memory, the memory configured to store the parallel packet stream, a parallel-to-serial converter configured to convert the parallel packet stream into a serial packet stream, and a serial line driver configured to transfer the serial packet stream to a device under test.
