In Stage Setup, press the Blend Maker button. In here you can say that you want a Quad layout (2 x 2)
With a certain percentage overlap or 0 if that is want you want to do.

What is it that you are trying to achieve here?

Hi everybody I'm working on a show for Saturday evening and I'm having some trouble displaying my images on two projectors.

I've tested it on two MacBooks both running on Big Sur (11.7.10), both with Isadora 4 (4.0.2) and both using the Plugable Triple Display, via their DisplayLink Manager (1.9.0 Build 148). 

On the newer MacBook 2019 I'm able to see my videos in the stage preview but when I push them to the projectors the projectors display only gray.

On the older MacBook 2014 I'm able to see the images no problem. It actually works on the older Macbook and not the newer one.

Very strange.

I've started and restarted both computers and I'm at a loss of what to do. It really should be working, The only difference I could imagine is that they have different graphics cards and processors. But shouldn't it work on the new laptop if it could work on the old one? 

I'm considering updating the newer MacBook (the one that doesnt work) with OS12 (Mohave). Should I? Any advice?

@skulpture

thank you Graham, but that’d give me 4 x 1080p outputs which is not what I want.

@mark_m By default I am sure the datapath will be set up in a 2x2 configuration. So in Stage Output, you will need to do the same. 

@dusx Great thanks Ryan !

Hi folks,

I recently acquired a Datapath FX4. I want to incorporate this into my setup in order to make sure that Isadora's stages always go to the same projectors.
I need some help in setting this up. I am using the Intel NUC Windows 10 computer in my profile below and Isadora 4.01

The input to the FX4 is 3840×2160 via Display port.
I have three stages, all in 4:3 format.
I have three projectors:
For stage 1 output the projector's native resolution is 1900 x 1200, and I'll set that to 4:3 aspect.
For stages 2 and 3 the projector's native resolutions are 1400 x 1050, which is already 4:3
The Datapath FX4 sees all the inputs and outputs correctly.

What I can't figure out is how to set up the stage setup in Isadora, and the Walldesigner software to do this for me....

Any help appreciated. Tagging @keftaparty  and @DillTheKraut who have both posted helpful things about the FX4 before.

Thanks in anticipation

Mark (not that Mark who would know how to do this :-) )

@armando

It is done you have an account key. You login on the Izzycast -> get it page with your account key and then create the reserved session id.

You can watch a short video walking you through the process here: How to Create an IzzyCast Reserved Session ID (youtube.com)

I was also seeing bad image quality in the Blackmagic Media Express Capture Window

 Hmm. I wonder if its possible that an interlaced capture is coming from a progressive input. 

Perhaps try setting the output from the other computer to the opposite of its current setting. So if its 60p try 60i (or vice-verse. I don't think Blackmagic generally allows you to capture with mixed settings but perhaps this is a special case)

@nic

Can you tell use the make and model that didn't work for you? It may help others in the future, and will allow us to expand our testing.

Hello,

how is a reserved session ID created ? At the purchase moment ? I don't see a way to do it on the website nor on the purchase portal.

Thanks

Armando
