    These numbers has to come from the processor manufacturer.
    From what I see here, the active horizontal pixel is 1024. Active vertical line is 820.
    Total lines include active lines and blanking period.

    Blanking period could be any arbitrary number generated by the processor. Please check with the processor manufacturer.

    Best Regards,
