I’m sorry if this is a simple fix like use vlc
To explain, images display correctly that’s not the issue at least. The problem I have is that videos uniquely will not play correctly. It’s been zoomed in on my church’s mac to the second display using hdmi.
I tried it at home, and it works. I do have to select the media/videos multiple times. Still, when the Mac is connected at the church even the preview will show a zoomed in image.
