DisplayPort to HDMI Adapter

I’m using a DisplayPort to HDMI adapter to get a display output, but it’s not working. I’m running JetPack 4.6.3 on a Jetson Nano core board, and the carrier board is the DevKit.
How can I resolve this problem?

Is the adapter a active one?

Thank you for your response.
I’m not familiar with this.

Please get a active adapter. Passive one cannot work on Jetson nano.

I will test it and let you know.

I used an active adapter, but I’m getting this error and there’s no display.

Please try other cable or directly use a native DP monitor.

Thank you for your reply
I have no issues with a direct DisplayPort connection, but I want to use a DisplayPort to HDMI adapter.
Is there any way to solve this problem?

No, this looks not a software issue. You can only try different cables and monitors.
