I could ask this on Modul8’s support forum but figured the problem might be more suited here.
I have modul8 output to TH2GO (2 devices * 1024×768 = 2048×768 combined resolution). When output to Syphon, I open up Syphon Recorder 2. Although I’ve set preferences in Syphon for 2048×768 recording, it appears Syphon is only able to pick up the center portion of Modul8’s output. So in other words the left/right sides of the full output are chopped off.
