@woland yes! thanks, it's pretty much the same idea of using a TripleHead right? I'll try this

 Yes, sort of. Making it one big video really helps things stay in synch. You may run into issues if your aspect ratios differ though. This method is also excellent when you're trying to edge-blend content across multiple projectors.

@woland You could also look at the Blackmagic cleanswitch, it is a bit of a tricky beast as it will work better with reference (or reference SDI input 1). This would give you a clean switching matrix that could be more useful than a simple mixer. I am pretty sure it also uses UDP, if Izzy gets UDP (it's been knocking around on feature requests for a while) then you could control it within Izzy.

does anyone have any experience  using Isadora on a 2018 15in Macbook Pro?

I am interested if everything is working OK with 3 or 4 HDMI projectors attached to the USB C ports? I would appreciate your feedback.

many thanks,

@dusx I see. Thank you

OK so the reviews on the Sanho suck - haha - mostly disconnect issues.  Brrrr!

But this one seems better:

I recently bought a Datapath VisionLC HD2 HDMI capture card and I wanted to share my success.

Above you can see it capturing an output from isadora running at 1920*1080 and up-scaling it to 3840*2160 (see below). I have since read it can capture a single HDMI at full 4k - which I will try one day.

The hardware cost £435 which is pretty cool as this can capture DUAL HDMI inputs. So its almost £200 a channel input capture.

Frame delay is minimal but the quality is amazing. 

It's also: 

PCI Express Gen 2 x 4 low profile

And it is indeed low profile! I was very tight on space.

I have done now hardcore testing yet but it works and I will keep you posted on my research.

I've definitely seen the draining battery issue when charging through display adapters - because those adapters don't always (or even usually) pass the full 85 watts through. Plugging directly into the macbook itself 'fixed' it the one time I ran into it. That may be an issue with four display adapters connected, but something like this should deal with that (puts both displays on one physical port, and leave the other open for charging).
