Send HDMI signal to 10 monitors with AV input?

Question

Iron

Good day everyone!
In general, there is such a task - supplying an HDMI signal to 10 monitors with an AV input.
Raspberry Pi 2
HDMI to AV Converter
10 monitors (NTSC, PAL) with AV input Question #1: Raspberry has
AV output 3.5mm jack 4 pin. But how to send a video signal to 10 monitors at once (with AV input)?
Question number 2: In which case will the video signal be better if you play HD video - through the native "Malinovsky" AV output or through an HDMI output and a converter (HDMI to AV)?
Thank you.

Answer 1

It ?
Regarding the second question: I could be wrong, but in my opinion, FHD cannot be transmitted by analogy.

Answer 2

You will not transmit FHD using any of the analog technologies, the maximum that is squeezed out of the analog is 1080i with a component signal, with composite RCA AV, which is raspberry, that the adapter will still have 520p at the output. So the extra converter here nafik gave up when the chip itself already has composite support on raspberries.
