Recommendations for non‑HDMI monitor options for Jetson

Hello,

I’m evaluating non‑HDMI display options for an NVIDIA Jetson Orin Nano/Orin (or specify your model) project and would appreciate your recommendations.

Which non‑HDMI display interfaces do you recommend for reliable operation with Jetson modules (best tradeoff of performance, driver support, and power)?

Best regards,

Mustafa

You need a monitor which supports EDID reporting of the monitor’s specs. This includes HDMI and DisplayPort. Some VGA monitors might pretend to support this, but they only support an older protocol which the drivers won’t work with. The digital DVI-D works, but not analog. In HDMI this is the DDC wire, and it uses an i2c protocol to inform the GPU what valid modes are.

Monitors which don’t have this won’t work because the drivers were not written to support setting modes in any other way. The exception to this is that there is a fallback mode in case no EDID is detected. You could rely on the default mode when no EDID is present, and some people go so far as to edit the kernel to pick a default mode which is more desirable.
