Hooking your phone up to your TV with a wired HDMI connection isn’t as convenient as casting from your phone to the TV, but wired connections do offer a more reliable streaming experience.
The simplest way to physically connect your iPhone to your TV is to use an HDMI cable from your phone to your TV’s HDMI port. You’ll need an iPhone-to-HDMI cable adapter to connect the HDMI cable to your iOS device. It’s called a Lightning Digital AV Adapter. You can get it direct from Apple for £59.99 or a bit cheaper (£54.19) other websites.
