it would be cool, if there is a Datapatch FX4, which is recognized as 4K or 3840x2400 display by macOS, that you could have 4x 1920x1080 / 1920x1200 displays in the output destination. Similar to the TripleHead.
is there any progress for this feature? Of cause I can do a workaround with Syphon/Spout chain to get separate display areas. I use this also for layered compositions with the DMX light control, but imho there could be less latency (I know, it is not much) if there would be some sort of internal container solution..?
