OK, thanks, I can see how that would work. So far as I know, the camera (which is actually a Sony A6000, not really a video camera :) *only* delivers one format, which is 1920x1080 @59.94 progressive, but I have no clue about its pixels (seems less likely they'd be configurable than the more obvious choices).
But I suppose the only thing that really matters is what the output of the splitter is. Any thoughts on how I can probe this? I have a monitor that I have intermittently connected on the other side of the splitter too--that's why the splitter is there--and its menu tells me only the resolution and frame rate info, not pixel type. (but to be clear, it makes no difference whether that monitor is connected or not)/ Otherwise, I guess I just find out what all the options are and try them one at a time (or buy a new splitter, which might not be a bad idea overall!)
