hello nv team
Now I use the self-developed carrier board with the orin nx module, I brush 35.5.0, and then use the 4k display, the system enters the resolution is 4k, and now I use the same set of devices to write version 36.3 into the only 1920x1080
I am now brushing the official bsp, using jetson-orin-nano-devkit.conf, and I have only changed the eeprom related value. Now I use the xrandr command to see the DP related, the current HMDI interface does not have 4k resolution, is there any file missing? Could you take a look for me, please

預設的display mode都是DP mode. 如果你要用HDMI你需要重新改device tree裡面DCB的設定
這件不管是35.5.0 或是36.x都是一樣的.

As for version 35.5, I have made modifications and quoted the file tegra234-dcb-p3767-0000-hdmi.dtsi, but I did not find the corresponding dtsi file in version 36.3. Could you please help me have a look

thanks

Hi,

rel-36.3上的p3509-a02-p3767-0000.conf 有提供範本. 裡面的欄位都得照著設定.
