Chapter 9. Display

Orin module designs can select from either VESA
embedded displays, and HDMI or DisplayPort (DP) for external displays. Only one interface is
available. However, DisplayPort does support multi-head display through MST.

Notes:
1. In the Direction column, Output is from Orin module. Input is to Orin module. Bidir is for Bidirectional signals.
2. The direction shown in this table for DP_AUX_CH[1:0]_HPD is true when used for Hot-plug Detect. Otherwise, if used as GPIOs,
the direction is bidirectional.
A standard DP 1.4 or HDMI v2.0 interface is supported. These share the same set of interface
pins. Therefore, either DisplayPort or HDMI can be supported natively.
