Chapter 9. Display

Jetson Orin NX designs can select from either VESA
embedded displays, and HDMI
available. However, DisplayPort does support multi-head display through MST.

Notes:
1.
In the Direction column, Output is from Jetson Orin NX. Input is to Jetson Orin NX. 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.
