12 projector output

[ray]

Hi all

Does anyone have any tips for running 12 or more projectors from one computer? I already have an rtx 4090 and an rtx 3070 installed but want to run at least 4 more projectors . 

Thanks,

Ray

Get a datapath FX4 or similar. It takes a single 4k input and splits it into quads; then you get 4 individual FHD outputs.https://www.datapath.co.uk/dat...

I like the Blackmagic Decklink Quad (8 switchable in/out). It's under Capture and Playback, here: Products | Blackmagic Design

The one I have seems to have been replaced by a newer version, but I found it on eBay: Blackmagic Design BMDPCB143A DeckLink Quad PCIe SDI Capture Card | eBay

Cheers,

Hugh

 This would be my suggestion as well

@DusX Could you please provide advice about working with multiple graphics cards on Windows? 

I always forget if this is a no-no or something that's fine to do after some specific configuration.

I personally did up to 10, using a Blackmagic Decklink Quad (8 Outputs), and two HDMI ports (control monitor / additional monitor for the backstage crew)

With a RTX 4090, and a speedy CPU you should be able to push that to do a Blackmagic Decklink + a Datapath FX4.
