Please do not echo the noise of similar questions and answers. None seem to meet my need.

What is the minimum set of config.txt commands that I need to ensure that my Pi 3B+ outputs to composite when it powers up?

For example...

# First Video Display
framebuffer_priority=3

Normal NTSC


sdtv_mode=0


Disable or Enable HDMI


hdmi_ignore_hotplug=1  # Disable HDMI (for Composite)


4:3 aspect ratio


sdtv_aspect=1

Those commands don't seem to work for me. Does the order matter? What will do what I need?

  • have you tried https://raspberrypi.stackexchange.com/questions/41796/composite-video-on-boot – Jaromanda X Jul 17 '20 at 04:04
  • If there's no HDMI connected then your RPi3B+ automatically boots to SDTV. It defaults to state 0x40000 [NTSC 4:3], 720x480 @ 60.00Hz, interlaced so PAL users may need some tweaks in /boot/config.txt. – Dougie Jul 17 '20 at 08:51

Make sure that hdmi_force_hotplug= is either 0 or commented out. You shouldn't need anything else, just don't plug in HDMI and it'll boot to composite mode.
