Yellow monitor output

Bought an old monitor, works great. It has a yellow rca jack hanging where it connects to the computer. Does anyone know it's function?

Sounds like it has a built in microphone.

Now there's an idea. I.ll check that out.

I have a monitor stuck on top of a wardrobe with that wire and connection, you can hardly notice the microphone though, it is barely a pin prick in the top of the monitor.

Never actually tried the microphone though.

What make and model is it?

HP pavilion M-50. Looks like it had speakers on the sides at one time.

The basic details for it are located here. The full details are located here.
