If you have a smart TV
1) Make sure your Android device is connected to the same wifi network as your TV.
2) On most Android devices you simply go to "Settings > Connected devices > Cast screen" and select your TV or casting device from the list (e.g. LG TV, Roku stick, or Chromecast). However, it varies by device, so please search online for relevant instructions.
If that didn’t work / you don’t have a smart TV
Don’t worry, you can still connect to your TV. Just pick up a third-party casting device, like Chromecast or Roku – which can be purchased online for as little as £10. Alternatively, you can connect to your TV manually using an HDMI cable. While a wired setup isn't as convenient as casting, it's very straightforward and reliable. Depending on the make and model of your TV, you’ll likely require a Type A HDMI cable, along with an adapter to connect it to your device.
