It's the hdmi output from another mac.Resolution is 1080p60.I tried the three video setup (scale to smallest, largest, default).With or without antialiasing...Anyway, i tried it on a new patch, video in watcher straight to projector, so there should be no scaling nowhere.When i let the mouse on the link, it tells the output from the video in watcher in 1080p60For now, i'm using spout/syphon from madmapper to have the good image quality.Once again, the setup was tested both on mac and pc, with a decklink duo 2 and a decklink 8k pro.
