Foolishly, my wife raised the question of how to do this on a subforum of a consumer forum dedicated to saving money. She was told to purchase a Google Chromecast, as this was the original of all 'casting' devices. So. We spent £29 on the word of a complete stranger who sounded convincing but who we now realise knew absolutely nothing about what he/she was talking about. The Google Chromecast is useless, and Google knows it but omits to mention its incompatibility with Apple products in its Chromecast publicitity. We should've known better than to trust to an Internet forum for genuine, dependable advice. And yet here I am, back again on just such a website. We have a 10 year old Sony Bravia non-smart TV, still in perfect condition and working faultlessly. For its time, it was incredibly well equipped: no less than 4 HDMIs. We're using 3 of them right now for a Roku stick, an Amazon Firestick, and a connection to our Humax recorder. The fourth HDMI port is the one into which we've plugged the £29sworth of uselessness from Google in hope of being able to do that which we were told Chromecast would do: cast / mirror what's on screen on our iPads (either mine or my wife's) to the TV screen. No such casting/mirroring occurs. When contacting Google for help, we're unhelpfully told all about receiving YouTube on Chromecast -- pointless, really, seeing as YouTube is an app on both the Roku and Amazon Firesticks. We don't need to cast/mirror YouTube at all. What we're actually trying to do in this, the start of the second decade of the 21st Century, rather than the closing years of the 20th, is mirror a video playing in the Internet browser of our iPad. My wife uses Safari. I use Firefox. We're interested in just one video: a rolling webcam broadcast of a place of great sentimental appeal to us both. The webcam is NOT screened on YouTube. I'm currently undergoing not-too-good health (post-stroke fatigue) and would be considerably cheered up to be able to have the webcam transmission on the TV screen now in our bedroom. However, as noted, despite making seemingly endless enquiries, we seem to have exhausted the reservoir of experience and expertise that may exist beyond ourselves. My wife has even been told to get an Apple TV (whatever that is.) I well recall being able to screen cast / mirror whatever happened to be on the screen of my Samsung Galaxy Tab A way back when, but it would now seem that what's possible for owners of devices considerably cheaper than those made by Apple is absolutely not possible for those who stump up the premium to buy Apple.
