If you have an iPhone and want to use it with a high-definition television, you’ll need to connect the phone to the television via an HDMI cable. Here’s how:

  1. Open the “Settings” app on your iPhone and select “General.”
  2. Under “Display & Brightness,” select “HDMI.”
  3. Under “HDMI Output,” select the HDMI port on your television that you want to use.
  4. On your iPhone, open the “Photos” app and select a photo or video to play back. Tap the screen twice to open the menu and then tap “Share.” Select “Send via HDMI.” If prompted, enter your password or PIN. The photo or video will be sent directly to your television screen. ..
