1. Cable connection (USB-C/Lightning to HDMI)
This is the most reliable option because it doesn't depend on wifi. You need a "USB-C to HDMI" adapter or cable (Android) or a "Lightning Digital AV" one (iPhone), which you connect to your phone on one end and to a free HDMI port on the TV on the other. The TV will show exactly what's on your phone's screen.
2. Chromecast or Smart TV with Google TV
If your TV has Chromecast built in (or you have a Chromecast device connected), you can send content directly from apps like YouTube, Netflix, or Google Photos:
- Connect your phone and the TV to the same wifi network.
- Open the app (for example YouTube) and tap the "Cast" icon (a screen with waves, top right).
- Select your TV from the list and the content will start playing on the TV.
3. AirPlay (iPhone only)
If you have an Apple TV or a Smart TV compatible with AirPlay:
- Open Control Center by swiping from the top-right corner.
- Tap the screen mirroring icon (two overlapping rectangles).
- Choose your TV from the list. Both devices need to be on the same wifi network.
4. Miracast / Screen mirroring on Android
Most Android phones have this feature built in, although the name changes depending on the manufacturer ("Smart View" on Samsung, "Cast" on others).
- Swipe down to open quick settings.
- Look for the "Cast" or "Smart View" icon and tap it.
- Select your TV when it appears in the list.
5. Which option to choose for your situation
- Old TV without wifi: cable connection.
- Smart TV and you want to watch Netflix/YouTube: Chromecast or Google TV.
- iPhone and Apple TV: AirPlay.
- Android and you want to mirror the whole screen (for example, for a presentation): Miracast/Smart View.
