It is much more simple... it is up to the app author. If they don’t want you to display on an external screen they disable the ability.

I have my internet through the cable company. They have an app that shows live local stations. They don’t allow it to be shown on a big screen unless you subscribe to the cable service.

One way of doing this is to buy a (very expensive) Apple Lightning to HDMi connector and connect your device (iPhone or iPad) to an HD TV using an HDMI cable. Bingo! Only sometimes it doesn’t work… it’s OK for example with Netflix, but there are other apps (NowTV in the UK for example) that report that the connection is not allowed. This seems to imply that Apple have an API for this feature that is somehow restricted - maybe you have to pay Apple to implement such a link. I was thinking of doing something like this in LC, but I need to understand this restriction first.
