Raspberry Pi Pinout

DPI - Display Parallel Interface

DPI (Display Parallel Interface) is a 24-bit parallel interface with 28 clock and synchronisation signals. The Pi uses a cut-down, 6-bit, 22 pin version omitting the least significant R, G and B colour bits.

DPI, combined with a simple adaptor consisting of 20 resistors, allows you to add a VGA connector to the Pi which supports resolutions from 640 x 480 up to 1920 x 1024 at 60fps and 6bits per channel.
