HDMI has no OUTPUT on dragonboard 845c

We have Debain OS gievn in the documentation page running on the dragonboard 845c.

After connecting it to a HDMI screen we get no Signal output on the screen as mentioned on the documentation page.

Is there any procedure for getting an output over HDMI that hasn’t been mentioned?

This is the output on serial console when db845 is connected to a linux host system.

Could you please share the full log (from start) (e.g. via pastebin) with the HDMI Display connected.
