Dual Screen In-Car Setup (Pi 3)

Fri Mar 09, 2018 12:49 am

Currently setting up a Pi 3 being used in a dual screen in-car entertainment system running Kodi.

I purchased two 10.1” (1024x600) portable car DVD players than can share the same HDMI video source via a composite video cable connecting the two screens:

I’m trying to decide between using the composite video cable to split the source between the screens, or using a HDMI splitter so both screens get a digital signal directly from the Pi 3.

Also, if I’m not mistaken the Pi 3 can not output to two HDMI displays at the same time? So a HDMI splitter would be required to achieve this.

Any thoughts or suggestions would be greatly appreciated, thanks.

I've seen plenty of splitters that convert multiple sources into one output so they can share one monitor, but alas, the reverse is not so straightforward.

I don't think such a product actually exists for HDMI.

AVLINK HDS12 - 4K HDMI SPLITTER 1X2

4K HDMI splitter to connect a single HDMI source to multiple displays at the same time. Use with HDMI cables of a combined 25m per output for HD resolution, or a combined 16m per output for 4K resolution, without signal loss.

Looks to be about £25.

HDMI video splitters definitely do exist, as pointed out by Mortimer, but I’m wondering if a digital vs analong signal would even make a difference at 1024x600?
