I know there are workarounds for this, i will address those below, but I Multi View constnatly creating a cumbersome a frustrating experience for me, when I am simply trying to use my Samsung Frame TV to see ONE thing at a time, and not several. The most common user scenario for me is that i am tryring to share something from my mac, and upon airplaying, it opens into multiview, when i only want to see what i am sharing. This happens even if my TV was initially off, of course depending on what function was used last. But my TV has been entirely off, which actually does happen quite often,. then it will happen upons sharing. I know as discussed in other forums, that one can click the return button and exit multiview or use the micrpohone to say the same thing (oh and then you just have to save a preset first, also annoying...), but the fact that I as a user have to click anything, leads to a poor viewing experience. Why cant i just shre someting to my TV, sit down and enjoy just that - without seeing some abnnoying fancy new feature I never requested? It seeems somebody got a little to in love with their own innovative new features...
I have been looking for this option for a long time - thanks a lot!
Here is my workaround. 1. Go to the internet app on the TV, and choose a screen, I chose Google. 2. Turn on screen mirroring on your Mac. 3. Go to photos and play a slideshow from one of your albums. Everything then works find.
