Thanks

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.

Thanks a lot but I already know all these solutions. I still think it would be better and more logical if the Wave Generator actor didn't start automatically

here's a user actor i just made: Go Wave Gen

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

if the time needed to wait before triggering the start of the Wave gen is longer than the duration of the Wave, then you can set it to initialize at 'once' and then mask the output of the first cycle with a Gate:

Or you could make it slightly more complex by initializing the Wave Gen to something very short, then sending the actual Frequency when triggering it to start again:

 The Wave Generator starts automatically when the scene changes. It would be great if the default behaviour wasn’t to start automatically, as this can be achieved using an ‘Enter Scene Trigger’ actor.

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.

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

Eva
