Hello Fellas!
Did ever somebody try a Unit from the Matrox Extio Series for example an F2408?
You can get 4 Outputs up to 2560x1600 each on a distance of up to 1000m with fiberoptic cable.
So Delay shouldnt be an issue.
But i never saw or heard somebody would use it for Resolume or Mapping so im a bit confused where is the negative point to use one like this instead of an DPFX4 for example.
