I got two of these doctor's office projectors at the 2015 NMRA National Convention because two of our projectors only had VGA inputs. They worked great with the HP Stream Book cloud computers that we used to work with PowerPoint. They also worked well with multiple laptops brought by individual doctors. However, a few months later I tried to use one of them to convert the output of a MacBook Pro (sorry, I don't know the model) that belonged to a doctor from a mini-meeting. MacBook refused to recognize it! Fortunately, we tested this combination before the clinician appeared in front of the audience, so we could export the Mac presentation file as a .pdf to a flash drive and use it with one of HP's streaming books. I haven't used them with better projectors so I can't say they were "perfect".
