Hi! I'm using armbian Jammy on my orange pi 5 with installed xfce desktop.
I'm trying to connect it to a small HDMI screen and it doesn't work. It shows "no signal".
I tried to use another screen (different model, resolution, manufacturer etc.) and it works. Then I tried to use non working screen with jetson nano and it works without any actions.
So, the problem is with orange pi with armbian and this specific screen.

 

Here is the result of "xrandr -display :0" launched trough ssh:

Screen 0: minimum 320 x 200, current 1024 x 600, maximum 16384 x 16384
HDMI-1 connected primary 1024x600+0+0 (normal left inverted right x axis y axis) 476mm x 268mm
   1024x600      59.82*+
   1920x1080     60.00    50.00    59.94  
   1920x1080i    60.00    50.00    59.94  
   1280x1024     75.02  
   1280x720      60.00    50.00    59.94  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   720x576       50.00  
   720x480       60.00    59.94  
   640x480       75.00    72.81    60.00    59.94  
   720x400       70.08  
DP-1 disconnected (normal left inverted right x axis y axis)

So, orange sees the screen but doesn't show anything on it.

There was an instruction with the screen for raspbian. It says that I need to change config.txt with this content:
 

max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=10
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0

But what are analogue steps for the orange?

Armbian works perfectly fine on 1st grade hardware.

I'm not here to blame somebody or something if you thought that I am. I want to find somebody who maybe knows this problem and how to solve it.
I have a problem with official orange pi, official armbian image and some display which doesn't want to work with them but works with another mini PC with another OS. But there is the display which works with both so it is not an issue with each piece separately. It is something between them. And if somebody has an answer - I would be glad to have it too.
