  12  Data (SDA)
  13  Horzontal Sync
  14  Vertical  Sync
  15  Data clock (SCL). Should only be used for DDC2 devices

  There are 3 different protocols defined for DDC:

  DDC1 - A unidirectional (display to host only) serial comm system which
         provides basic display ID and feature support information (including
         supported timings, display size, colorimetry and gamma, etc.) to the
         host. This uses pin 12 on the 15-pin "VGA" connector as a data line.

  DDC2B - Adds clock (pin 15) and return (pin 11) to enable at least ID
          information to be obtained via an I2C interface. I2C is a
          bidirectional interface, but display control via DDC2B is not
          defined at this time.

  DDC2AB - Full ID and control of the monitor via ACCESS.bus. As ACCESS.bus
           is basically a command and protocol definition on top of the I2C
           hardware interface, this uses the same lines as DDC2B.
