DSI Video

The final video output on the Pi can be found above the SD card slot on the top of the printed
circuit board—it's a small ribbon connector protected by a layer of plastic. This is for a video
standard known as Display Serial Interface (DSI), which is used in the flat-panel displays of
tablets and smartphones. Displays with a DSI connector are rarely available for retail pur-
chase, and are typically reserved for engineers looking to create a compact, self-contained
system. A DSI display can be connected by inserting a ribbon cable into the matched connec-
tor on the Pi, but for beginners, the use of a composite or HDMI display is recommended.

Connecting Audio

If you're using the Raspberry Pi's HDMI port, audio is simple: when properly configured, the
HDMI port carries both the video signal and a digital audio signal. This means that you can
connect a single cable to your display device to enjoy both sound and pictures.
Assuming you're connecting the Pi to a standard HDMI display, there's very little to do at
this point. For now, it's enough simply to connect the cable.
