Note: It may not be working because of which cable I am using.

So I have a Raspberry Pi 2 Model B and I want to connect it to a computer monitor that only takes composite video input.

This is what I'm using to output composite video:

I've edited the config.txt file to ignore HDMI output and use NTSC video. I've also commented force_hdmi so that it wouldn't force that output.

But this is all I get:

No input signal.

What should I do?

Ps I'm running on the Raspbian operating system.

Try switching the red and the yellow.

  • Explain further. Red is audio, how would this work.

    @ZacharyVincze Red is only audio if the red lead is connected to the audio tip in the socket. There is no standard. I had to swap two leads to get composite video to work on my Pi2.

I think if you have to press key 2, 3 or 4 to change to compose video, also add this line on config.txt :

sdtv_mode=2

Also

hdmi_ignore_hotplug=1

However it may be the wrong cable as explained on raspberry.org

  • I think it may be the cable as I've already put sdtv_mode=0 (NTSC video) and hdmi_ignore_hotplug=1.

The red plug contained my video (on my cable) also. Your mileage may vary. Do like I did & switch them around until it either works or doesn't.
