-The following display outputs are supported on the board:
-* Composite video (NTSC and PAL) via an RCA plug (the yellow socket on your TV) or [[SCART]] socket.
-* HDMI 1.3a standard output.
-* Display Serial Interface (DSI) - via unpopulated 15-way flat flex connector.
-−
-These interfaces allow the use of a broad range of displays, including:
-* Televisions (HDMI or composite).
-* Computer monitors (HDMI/DVI-D cable) (VGA monitors would require either a composite or HDMI to VGA or component scan converter box).
-* DLP/Laser Pico Projectors (HDMI/DVI-D cable).
-* RAW LCD panels (DSI + interfacing hardware)
-* Composite and HDMI outputs can not be used at the same time (one or the other.)

-The SOC (system on a chip) does not support any kind of analog component video, including VGA, since the SOC is designed for mobile phone use where this would not be a requirement. Additional componenty would be needed to generate RGB signals. Additional componentry would push the price beyond the $25 target and therefore won't happen.
