[ANSWERED] Linking 4-6 projectors

Eva

hello there,

I hope someone has a good tip.

I need to make an easy system, where I can link 4- 6 projectors for VJing and be able to setup so I can make a change of VJ without heavy interventions. I have, I think its a Black magic ATEM mini pro. But what do I need of hardware to connect the projectors and collect the signal through to one hdmi? I can play the same video through all of them:) apart from hdmi cables:)

I hope that makes sense:)

All the best

Hi Eva

At a quick glance, it seems that a simple HDMI splitter might be the solution to your query?

I am assuming the projectors are in a proximity to the laptop and no SDI or similar is needed?

The Atem Mini will only loop the signal in/out. The units normally have 4 inputs and one output. If you are using the atem, then put the HDMI splitter in line from the output of the atem.

If you have another laptop or media player, then the atem might be handy. Otherwise it might not help etc.

Your cheapo splitter is normally 4:1 (4 outputs to 1 input). Obviously, if you are looking for more than 4 projectors, then you would need a larger model or a second unit. I would keep the HDMI runs to as low a measurement as practical.

You can pick up 4:1 4k HDMI splitters for less than €100.

There may be better recommendations of brands here from others but you could pick up a cheap splitter/decent quality cables and trial it without much cost.

The set up should be plug and play here.

I remember the pre-HDMI days when projectors ran on VGA, they usually had a VGA out so you could daisychain them together.

I second the HDMI splitter suggestion. There are even 1-to-6 and 1-to-8 HDMI splitters, but the cheapest option would likely be two 1-to-4 HDMI splitters.

thank you people!

Yes I need to change VJ that is the second part. So I need to have two computers connected:)

you could add a HDMI switch into the mix before the splitter(s) - these are cheap and readily available - I bought one from a supermarket when I needed to solve the problem of 2 laptops into one projector.
