I don t find on odroid boot/config. Text

Where is it ?

And you have the file ?

gnubit

@peche take a look here:

https://pastebin.com/aMU3mkss (it`s the /BOOT/boot.ini file)

It should work ( I downloaded the xu4 image and edited the file, but I don`t have the hardware to test it on.)

what I changed:

I commented out:
setenv videoconfig "video=HDMI-A-1:1920x1080@60"

and added in it`s place:
setenv videoconfig "drm_kms_helper.edid_firmware=edid/1280x1024.bin"

I also commented out:
setenv vout "hdmi"

and added in it`s place:
setenv vout "dvi"

Hoping this might help

@peche first of all, learn to paste such code between triple back ticks blocks. The result is supposed to look like :

nice code block

which you'd write as :
```
nice code block
```
(you can copy this in your answer and replace the text of course)

Now, something is weird, because your boot.ini is supposed to looke like this. So you'd just have to add a # in front of the current video mode and remove a # in front of the mode you wish to use

@substring thank you but nothing
i will change the adaptateur hdmi / vga
or i buy a new screen with hdmi

@substring
hello I went to a computer store

I modified the resolsution
and I have the correct resolution that appears after the line choice that appears and
for my pc screen I had chosen that the

1280x1024 with data using generic information

setenv videoconfig "drm_kms_helper.edid_firmware = edid / 1280x1024.bin"

on the other hand the screen of pc in the shop displays no signal: 0000x0000 / 00hrz

I test another odroid the one with the fan
