Problema monitor con Raspberry

@mitu yes

@onebitcpu How do I change it? I don't know how

[mitu]

@angel1682 Insert your sdcard into your PC, them modify the config.txt file in the new BOOT partition that appears (don't format the card, if Windows asks you). Open the file and add the line mentioned

hdmi_force_hotplug=1

You can also try with:

hdmi_safe=1

@mitu do I just have to add or edit some lines? sorry but I'm not very experienced

[mitu]

You need to add one of those lines - at the end of the file, on a separate line.

[angel1682]

@mitu ok I'm going to turn on the pc and try, I'll let you know in 15 minutes if it works

[angel1682]

@mitu can I send you the photo of the config file?

[mitu]

Just copy the contents and paste it in the topic.

[angel1682]

I don't know where I have to write it and if I have to delete something

[mitu]

It looks like your config.txt file is already set to a certain resolution and has the hdmi_force_hotplug=1 option added. Did you modify the file ? Because the default RetroPie image doesn't have this settings.

[angel1682]

@mitu it took a long time to arrive at a good resolution, I had documented some small variations, but now I have forgotten everything, I am a non-programming nurse😂

[mitu]

I would comment the resolution lines (add a # at the beginning of the line) and also comment the hdmi_drive line. Try with these modifications to see if the video works.

[angel1682]

@mitu I apologize humbly but I don't understand what I have to do.If I send you the file you can edit it that at this moment I can't understand

[mitu]

In your file, you have these lines :

hdmi_group=1
hdmi_mode=19

Modify the line and add a # at the beginning of the line:

# hdmi_group=1
# hdmi_mode=19

Make a copy/backup of the file, just in case.

@mitu thanks a lot now works again😊😊😊
