If not, see VGA: DPI/VGA adapter for the Raspberry-Pi Rev 1.0, 8 September 2014 The video shown uses an adapter with 1% SMD resistors. There is a slight colour banding and with 6 bits per channel you have a maximum of 262144 colours. Double screen In contrast to the composite video, the DPI interface can be run independent of the HDMI. Thus next to the HDMI screen, the VGA can be used as second monitor. The software for that is still under development but I expect that to arrive in the next two week. Beware that running two screens at maximum resolution will really eat into your SDRAM bandwidth. In fact it has not tried yet, so it might not be possible. Where to buy Nowhere: you cant buy this anywhere for several reasons which you can find in the manual. But you can make it yourself, or find yourself an enthusiastic partner and have it made. All the data is in the public domain at Github:
