Problema monitor con Raspberry

mitu

We don't support 3rd party images - as it's outlined in the https://retropie.org.uk/forum/topic/3/read-this-first.
Try the RetroPie image from retropie.org.uk/download and we'll be able to provide support.

@mitu my mistake, with the translator, the image was made with the original retropie downloaded from the site, then I played a bit and put it away when I reassembled everything but on a pc monitor instead of tv I still have a black screen and not even the lan works me more😔😔

mitu

What resolutions does the PC monitor support ? When you start the Pi, do you get the boot 'rainbow screen' ?

angel1682

@mitu no black screen, the monitor supports 1600 * 900 60hz

mitu

Make sure the sdcard is properly inserted - it looks like the pi doesn't even boot. If that's not the case, then write the image again.

angel1682

@mitu already done, on the TV it works on the monitor instead of a fixed black screen😩

mitu

Is your monitor working ? Is the video cable to the monitor ok - how is the monitor connected (HDMI/VGA/etc.) ? What kind of Raspberry Pi model do you have ?

angel1682

@mitu the monitor is functional, the cable is new and from hdmi to DVI, Raspberry pi3b +

mitu

Does the monitor work - with the same cable - connected to another PC/device ? I'm suspecting a faulty or incorrect cable.

Do you have force hdmi set in /boot/config.txt
hdmi_force_hotplug=1

angel1682

@mitu yes

angel1682

@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

angel1682

@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.
