Hi
When I plug in my HDMI cable and want mirror screens to watch a movie on my TV I just get a picture of my background and in the bottom left corner comes a cog and in the bottom right side there are a lot of dots in a square but no more if I go over to HBO on the phone and start a movie then only the sound comes on the television but no movie only the same pictures that have always been when I start mirror screens
what to do?

@Rytter: If you have a Smart TV, have you tried Screen Mirroring wirelessly via Smart View to see if this helps? To proceed, swipe from the top of the Note 9 screen to the bottom and select Smart View from the Quick Settings menu, select your TV from the Available Connections, and you should be good to go.

If the above isn't applicable, please can you confirm what adapter you're using, if any, to connect the phone to your TV via HDMI?

@Rytter: I see. You will need a USB-C to HDMI adapter rather than a standalone cable to mirror to your TV. It doesn't look like we currently have these in stock, but please check out the link below as a reference point.
