HPD: Hot Plug Detect Input signal. +5V_HDMI electrical level signal.
For ESD protection, on all data and voltage lines are placed clamping diodes for voltage transient suppression.
Always use HDMI-certified cables for the connection between the board and the HDMI display; a category 2 (High-Speed) cable is recommended for higher
resolutions, category 1 cables can be used for 720p resolution.
Please be aware that only HDMI displays are fully supported through connector CN14. DVI displays, although having a similar TMDS interface, are not supported.

The Rockchip PX30 Processor includes an Image Processing Subsystem, that can
be used for video applications, like video-preview, video recording and frame
grabbing.
It is possible to access to the video input port through an FFC/FPC connector, type OMRON p/n XF2M-
1815-1A which is able to accept 18 poles 0.5mm pitch FFC cables.
