I recently purchased a $60 lightning to HDMI converter so I could watch xfinity stream on my TV rather than my small iphone screen. It worked at first but lately it won’t because of a license issue? What’s that all about? And why? What’s the big deal?
you can use hdmi with a desk/laptop as the 2nd screen use of a TV for a PC is grandfathered in as an exception to the HDCP restriction that blocks your phone from streaming to a TV from the Xfinity app.
