No HDMI on Raxda 3a 1.3

Hello

I have tried the default Debian xfce on a sd card and cant seem to get a video out. I have tried different HDMI cables and monitors. I managed to get via ssh nomachine on the board and was able get to the desktop on that. The odd thing is the HDMI is detected but doesn’t display a picture. Does anyone have any guidance on rectifying this?

So its booting but doesn’t display the output. But still detects the display.

Which image did you download? Your question is that HDMI is connected to the monitor, and the monitor has no image display?
