AGX ORIN 32GB carrier HDMI has been forced to 1080p@60hz, can not adapt to 4K@60hz

如果你也是在自己做的底板上碰到這個問題
那我這裡簡單說明一下:
你們如果使用的是預設device tree, 那行為就會跟NV devkit一樣. NV devkit預設的功能是DP port. 沒有HDMI port. 想要把HDMI功能打開就得照下面的post更改software.


Just to clarify. If you are also using custom board and hit this issue, then you need to modify the device tree to configure the display function. The default one is same as devkit so it is DP, not HDMI.
