How did you connect the LG 19M38A to the Orange Pi (which model?), because this montor seems to have only VGA input.

Second "problem" is that the monitor has "only" a resolution of 1366x768 which isnt much compatible to HDMI resolutions.

I think a 720p resolution could work, but we didnt know your Orange Pi model and we didnt know which armbian-version do you use.

 

Please do a

armbianmonitor -u

and post the link here + answer the question above, so that we could try to help you ;)

 

BTW: Monitor details at https://www.displayspecifications.com/en/model/5c53137f

Maybe you are trying to use some kind a HDMI-VGA adapter. My experience: Don't. Does not work so well.

Try to get a hand on another monitor which natively features HDMI for testing.

This is what I found http://ix.io/1MI

 

your link is to short, because there is no system info included -

only something like "import Data.Char"

The output after armbianmonitor -u shoud look like

root@opi-one(192.168.6.114):~# armbianmonitor -u
System diagnosis information will now be uploaded to http://ix.io/1Mjw
Please post the URL in the forum where you've been asked for.

root@opi-one(192.168.6.114):~#

maybe you missed the last character from the link while copying? ;)

What should I do now ? Please help me :(

 

from the log-data the problem is that the Orange Pi will use the (by your monitor) unsupported resolution 1920x1080 (FullHD:

[ 0.000000] Kernel command line: root=UUID=3a9456d1-b09a-446f-8a8c-ed11bd8b1b0d rootwait rootfstype=ext4 console=ttyS0,115200 console=tty1 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 loglevel=1 ubootpart=ada96ee4-01 ubootsource=mmc usb-storage.quirks=0x2537:0x1066:u,0x2537:0x1068:u cma=96M cgroup_enable=memory swapaccount=1

 

For you monitor you should switch to a 720p resolution like it is documented at https://docs.armbian.com/User-Guide_Fine-Tuning/
 

screen resolution on other boards:

nano /boot/boot.cmd

# example:
# change example from 
# disp.screen0_output_mode=1920x1080p60 
# to 
# disp.screen0_output_mode=1280x720p60

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

Edit of u-boot environment is also available at
armbian-config --> system --> Edit u-boot environment

from: disp_mode=1920x1080p60

to: disp_mode=1280x720p60

armbian-config is a shell-command and the control center of armbian.
but I dont know if this edit will create a compiled boot.scr out of the edited boot.cmd like in the documentation above.

You mean the problem is from hardware or software?

 

the "problem" ist only a software-configuration - your monitor isnt automatically recognized. Thats all.

 

And No sorry - I cant connect to your local SSH-session ;)

Wich resolution should I set it?

1280x720p60

 

Info:
https://www.lifewire.com/720p-vs-1080p-a-comparison-1847332

Also, most TVs labeled as 720p TVs actually have a native pixel resolution of 1366x768, which is technically 768p. However, they are usually advertised as 720p TVs. Don't let this throw you off, these sets will all accept incoming 720p, 1080i, and 1080p resolution signals. The TV will process and scale any incoming resolution to its native 1366x768 pixel display resolution.

1366x768p60 may be unavailable as mode.

İ did wrote 1280x720p60

 

Only editing the boot.cmd doesnt help if you didnt "compile" it to boot.scr and reboot

 

Do you use a desktop or server (headless) armbian image?

What do you mean about boot.scr ??

You can see at the end of boot.cmd these instructions :

# Recompile with:
# mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr
