That's usually from Samsung's own tablets and phones. Be sure to see if that's in the product features.
When I try to use the screen mirroring feature on my samsung TV to mirror my PC screen, I have no issues finding the TV on my computer and the TV shows that it has connected to my computer, however after it connects and the "Loading" logo comes up in the corner of the screen, the TV then says "The video data is not supported". Why is this coming up? What is the issue? Thanks for the help.
