I have a requirement to playback video on an LED screen which is 16,896 pixels wide x 1356 pixels in height, I will have to break this down to 5 outputs, 3 outputs at 3840 x 1356 each and 2 outputs at 2688 x 1356 each. I am building a workstation using a Threadripper 7980 64 core with an A6000 + A4500 GPUs with a quadro sync 2 card.
Now the system is still not ready yet but reading the nvidia quadro sync card manual shows that I have to use mosaic and have all displays same resolution.
My question is the following isn’t there another way when you don’t have identical resolutions to set one output as master and the rest to sync
To sync the scanout of multiple outputs, they all need to be running the same resolution and refreshrate. If the outs are on multiple GPUs, the GPUs must be identical.
I havent tested this myself (yet), but with the latest driver and firmware updates, we shall be able to sync 2 groups of outs, if they run EXACTLY the same refreshrate, but no longer the same resolution… it needs a dedicated sync card for each GPU and resolution though…
So -theoretically- you could run 3 outs from the one GPU, 2 different res, but exact same refreshrate outs from the other, identical GPU, and then sync the 2 groups to run a sync’d refresh.
This would need 2 sync cards!!, one per ‘mode’, per GPU…
We only support this when using the same GPUs, not your mix of GPUs …
