Corregir pantalla en negro al usar conversor HDMI a VGA con Raspberry Pi

Enviado por enekochan el 2013/05/28 Deje un comentario (11) Ir a comentarios

Si usas un adaptador de HDMI a VGA y la pantalla se te queda en negro es posible que modificando el fichero config.txt arregles el problema.

Si abres config.txt verás que tiene muchas líneas comentadas que se puede utilizar para modificar el comportamiento del puerto HDMI del Raspberry Pi. Esta es la configuración que me funcionó a mí usando un adaptador de HDMI a VGA y con una resolución de 1920×1080:

disable_overscan=1
hdmi_group=1
hdmi_mode=16
hdmi_drive=2

hdmi_group define el tipo de HDMI (si no se especifica el grupo o se pone 0 se usara el grupo por defecto indicado por edid):

hdmi_group=1 – CEA
hdmi_group=2 – DMT

hdmi_mode define define la resolución de la pantalla en el formato CEA o DMT.

hdmi_drive selecciona entre los modos HDMI y DVI:

hdmi_drive=1 – Modo DVI normal (sin sonido)
hdmi_drive=2 – Modo normal HDMI (el sonido se enviará si está soportado y activado)

Si quieres saber qué modos (hdmi_mode) están soportados por tu pantalla comenta las líneas de las 4 opciones (dejando así las configuraciones por defecto), reinicia y ejecuta estos comando:

Para los modos disponibles con hdmi_group=1:

sudo /opt/vc/bin/tvservice -m CEA

Para los modos disponibles con hdmi_group=2:

sudo /opt/vc/bin/tvservice -m DMT

Puedes ver todas las opciones en http://elinux.org/RPi_config.txt

  If you plug an VGA adapter to the HDMI out you can’t have sound from there.

    I plugged the speakers into the audio jack and I still have no audio.
    
    If I connect video thru the composite instead of the HDMI, audio work just fine.
    
    Any ideas?
    
    Thanks

Hi There,

How’s it going? I just got my Raspberry Pi board delivered a week ago. I had this ordered locally along with a clear case and a power adapter.

Eager to get started I bought a keyboard and mouse, SD memory card (16GB) and HDMI to VGA convertor.

Reason being my monitor doesn’t have a HDMI slot. I have formatted and installed Noobs 1.3 on the card.

So I go ahead and connect the network cable and start up the board. Nothing appears on the screen until I press option 2.

Then I see the familiar OS options screen and install Raspbian as default.

Install goes smoothly till I see the install completed message.

When I reboot all I see is a black screen. Any ideas on what to do next? Appreciate some advise.

Thanks

    Hi There,
    
    I managed to get it to work now. I Had to press Shift upon start up and the option is 1, NOT 2, for the monitor display using the cable. I managed to get into the config file and make the required changes.
    
    hdmi_drive=2
    hdmi_group=2
    hdmi_mode=16
    
    I then saved it and voila its working perfectly now.
    
    Thanks for your help.
