Hi! I need some help,and I’m pretty sure is someone in the forum that has an easy solution for this.
The thing is, I’m currently designing an exhibition where there are 4 projectors, each one has a video loop and, ideally, the loops had to be synced. This would be pretty simple if we could use a computer with four graphic cards, but it’s not possible.
Hello The instructions seem fine to me, have you used linux before? The instructions are made to be run in a terminal. If you plug screens and keyboards/mouse to the R-Pies you will be able to type them on each of them.
I can try to make a video of how it’s done if that would help?
I wrote a lib for this a few years back that’s been used by many successfully. Let me know if you have any questions. Generally the idea is to auto connect to a network and auto play on boot up, so there is 0 interface, just synced looping.
the thing i always recommend in this situation - if its not critical, forget about the sync. you’ll save yourself money, time and headaches
another option in your case would be QuadHeadtoGo, by Matrox. I’ve only ever used Triple, so you’d have to research the minimum requirements. But I figure it would be just as expensive as 4 standalone units as above.
in the Matrox case you would render one massive video, say, 7680 x 1080, and the unit then splits it correctly to the four projectors. depending on your layout config you may need cable adapters / conversion boxes etc, as traditionally HDMI cables arent super long.
