We want to be able to mirror an iPhone to a monitor in portrait mode, without black bars - full screen. We use it to show iOS apps and PoCs to customers and other teams in my company. Is that possible with an AppleTV? I've googled it and as of a few years ago, it was a solid "No". More recent posts are along the lines of - "try it". And then no reply. In theory I'd think this is doable, but AppleTV is pretty limited in features - so I don't know. Can that be done? Thx!
