Can you post a screenshot of your OBS preview? Need to see what you're meaning by "grain".

Ok, ended up putting an BlackMagic UpDownCross between the mac (graphics, video, ProPresenter6) and our video switch. Cleared up the problem immediately. Though I was hoping for a software solution I'm ok with a hardware fix.
