Hi All ,

I am new to Jetson nano user. I would to force the custom resolution of 480 X240 with 8.2MHz

Want to use Displayport.

If anyone done previously . please help me

All the display modes can only be come from EDID. Thus, if you want to custom resolution, then you can only customize a edid in the kernel.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

The mode you are using seems a little bit low. I cannot guarantee it would work or not.

The reason why we add some condition in the driver is because we may not support those resolution in hardware.
