I suspect that Beerbong doesn’t have his MC set to Fullscreen…as he also said earlier about switching off AOT on the mixer which is not the same thing.
EDIT…Please ignore me if you read any of that…what I was suggesting works only with MC on the same monitor as project…not possible to switch off AOT with it on the other mixer unless you stretch the project window which is what we are trying to avoid…DUH!!
