Custom resolution with Jetson Nano Developer KIT

[pkarthikeyan.ram]

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.

Hi Wayne,

Could you please confirm following changes in kernal is ok?

EDID.C:

1.Add the EDID values for 8.2MHz (480x240)

2. Set fallback = true

DP.C:
Comment the below line a

if (dc->edid->errors) {
return (mode->xres == 640 && mode->yres == 480)
? true : false;
}

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.
