RaspberryPi3 powering up but no visual HDMI - VGA

wolfmountaingames

I recently got a raspberry pi, but all my monitors are VGA so I went to the store got an HDMI to VGA adapter, and plugged in the screen, mouse, keyboard, and finally the pi. The red light came on so the power cord is working, but there was no visual at all it was as if the pi was not on. I read somewhere that in an older version if you changed a line in config.txt that it sometimes help with hdmi to vga, but I can not find config.txt anywhere on the preloaded card I bought. Can someone help me with this or link me to a confirmed working HDMI-VGA adapter that works with the pi?

 

Thanks,

  • Hi Andrew,

    I am a bit worried about that SD card you have....

     

    There are two hints that this may be the problem. I don't hear anything from you about the green light flashing a bit when you turn on the pi. The green light should go on and off irregularly for a while after you turn on the pi. If NO green light is seen at all the pi is not seeing the SD card.

     

    Secondly, you say something about not finding config.txt. The SD card should have a boot partition which holds the stuff needed for booting. It is a fat partition that should be visible using Windows. And there you should be able to find "config.txt", simply in the root directory.

     

    (Hmm. I don't know how NOOBS handles booting and if you'd be able to see that config.txt file on a NOOBS card. )

    On the NOOBS card the config.txt file is packed away inside of the \os\Raspbian\boot.tar.xz archive, presumably awaiting the user to select Raspbian from the NOOBS option list, at which point it is then will be extracted to the boot partition as per the Raspbian image.

     

    Within NOOBS however there are some display options available to the user:

    If your display remains blank, you should select the correct output mode for your display by pressing one of the following number keys on your keyboard:
    1. HDMI mode - this is the default display mode.
    2. HDMI safe mode - select this mode if you are using the HDMI connector and cannot see anything on screen when the Pi has booted.
    3. Composite PAL mode - select either this mode or composite NTSC mode if you are using the composite RCA video connector.
    4. Composite NTSC mode

    These are the files I see on root: https://screenshot.net/ryrcddl   I have found the boot.tar.xz archive where you said it would be, when I opened it  and opened boot.tar and config.txt was inside now to test out the uncommenting image
