We would like to use a 1920720 resolution display as a monitor.
Is Jetson ori nano able to output 1920720 resolution?
(we are using JetPack 5.1.1.)
If not, is there any idea to output 1920*720 resolution?
If the monitor EDID tells to output this mode, then it shall be able to.
But we still suggest to use common CEA modes.
I will expand on this topic: The older VGA connector had no way for the monitor to report its own specifications. One had to install a “driver”, which was in reality just a database of the monitor’s specifications. Digital DVI (not analog) and HDMI and DisplayPort have a wire dedicated to reporting the monitor’s specs. That wire is actually powered by the host computer so the monitor can be queried even if it is not turned on. The data is the EDID. If for any reason you use an adapter or other method that cuts the EDID availability, then the Jetson won’t be able to automatically configure for that. What kind of connector is used?
Thank you for answering my question.
Let me clarify my understanding.
Do you mean Jetson ori nano is able to display by monitor EDID and fixing driver both ?
And does CEA mode mean this URL below?

Thank you for supporting us.
Interface is Display port.
DisplayPort does support EDID. Thus it shouldn’t be an issue. Usually the problem is using an adapter from DisplayPort to VGA.
If the carrier board is custom though, then you would also need a custom device tree before the hardware could properly set up to reach the EDID data. You might want to mention if you have the NVIDIA Orin Nano developer’s kit. This is the model with no eMMC memory.
If this is a dev kit, then you usually have to flash the QSPI once, and then multiple SD card releases will work, but if you have not flashed QSPI at least once, then this might be the issue.
