Screen goes black after starting kernel, i've installed the latest version of Armbian. Before that, there was no problem. I was using Armbian debian server

What kernel? What version? Based on those data I assume everything is ok.

 

Wrote on mobile phone

Everything is ok at starting, I see the "Armbian" logo in the middle of the screen, then logs come at the left corner of the screen. it goes black after "Starting kernel" log. It is latest Armbian. Original kernel.

If it is neccesary, i can record a video.

Do you get a login prompt? If you do, nothing is wrong, just boot log is apparently directed to serial console.

I can see that

 

After that it goes off, just like in this photo

Sorry about that, please click "INDIR" to download. Its turkish, if you want i can upload it somewhere else, or just put it here

I see a relatively small square monitor, so you need to change the resolution manually using h3disp utility, assuming this monitor supports any provided resolution.

Default setting for the kernel is 720p if I remember correctly

It was working properly on previus build. And you are right, it is, and it should be supported. I'll try to use lower resolutions.

Result:
576i "input signal out of range"

720p50 not working

720p60 not working

Higher resolutions cant be subject on this monitor.

if your monitor is not of hdmi but of dvi type

then you need to use the -d switch in h3disp utility.

Thank you, finally. I hadnt read description of h3disp.
