Hi,all
How can I change the HDMI output resolution on linux system and SDK kernel driver? Now the default is 1920*1080, I need to change it to 1280*720.
I have referred to this article but it does not apply to me:https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_DSP_sk-am62-hdmi-display-resolution
The system supports 720p output
root@am62axx-evm:/opt/edgeai-gst-apps# cat /sys/class/drm/card0-HDMI-A-1/modes 1920x1080 1920x1080 1920x1080 1920x1080 1280x720 1280x720 1280x720 1280x720 720x480 720x480 720x480 720x480 640x480 640x480 640x480
Thank you.Wish you happy every day!

To change the HDMI output resolution on a Linux system with the AM62A7 platform, you can use the `xrandr` command to set the desired resolution. Here are the steps to change the HDMI output resolution to 1280×720:
1. Open a terminal on your Linux system.
2. Use the following command to list the available display outputs and their supported modes:
xrandrThis will display a list of available display outputs and supported resolutions. Identify the HDMI output (e.g., HDMI-1).
3. Use the following command to set the HDMI output resolution to 1280×720:
xrandr --output HDMI-1 --mode 1280x720Replace "HDMI-1" with the actual HDMI output name if it's different in your system.
4. After running the command, the HDMI output resolution should be changed to 1280×720.

Sadly, AM62a does not have xrandr installed, nor does it have apt or yum.

It looks like you are trying to use package management commands like apt, yum, and rpm on an AM62a system, but these commands are not found. This is likely because AM62a does not use the same package management systems as traditional Linux distributions.
