No Display with Debian Buster Desktop (Linux 5.10)

I am trying to install the image in title from onto my RockPi v1.72, but when I boot it, there is no display. The blue led casually blinks (not like there is an error), but I get no display output. Also, I get no host when I connect it to my computer via LAN(sharing the internet through LAN).

I am connecting via HDMI. Do you have any idea?

I think the problem is HDMI drivers, I can connect through serial interface…
I can make the link up again using ifconfig eth0 up
