What Do You Need Before Connecting?
Before connecting your smartphone to a Smart TV, check the following:
A smartphone with a supported casting, mirroring, or wired connection feature.
A Smart TV that supports a compatible connection method.
A Wi-Fi connection for most wireless methods.
A suitable cable or adapter if you are using a wired connection.
Both devices switched on and ready to use.
Not every smartphone and Smart TV supports every connection method. Always check the device specifications when necessary.
Method 1: Connect Your Phone Using Screen Mirroring
Screen mirroring allows you to display your smartphone screen on a compatible television.
Depending on the phone brand, this feature may have different names, such as Screen Cast, Cast, Smart View, or Wireless Display.
Step-by-Step Guide
Step 1: Turn On Your Smart TV
Switch on your Smart TV and open the relevant screen mirroring or casting feature if required.
Step 2: Connect Both Devices to Wi-Fi
For many wireless mirroring methods, your smartphone and Smart TV need to be connected to the same Wi-Fi network.
Step 3: Open Phone Settings
On your smartphone, open Settings and look for a feature such as Cast, Screen Cast, Screen Mirroring, or Wireless Display.
Step 4: Select Your TV
Choose your compatible Smart TV from the list of available devices.
Step 5: Allow the Connection
If your TV displays a permission request, accept it.
Your phone screen may now appear on the television.
The exact steps vary by phone model and TV brand.
Method 2: Cast Videos Using Compatible Apps
Some apps support casting content directly to a Smart TV or compatible streaming device.
This method is different from full screen mirroring because it may send supported video or audio content to the TV without displaying your entire phone screen.
How to Cast a Video
Open a compatible video or streaming app on your smartphone.
Make sure your phone and TV or streaming device are connected as required.
Look for the Cast icon inside the app.
Tap the Cast icon.
Select your compatible TV or streaming device.
Choose the video you want to watch.
Not every app supports casting, and available features depend on the app and connected device.
Method 3: Connect Your Smartphone Using an HDMI Adapter
A wired connection may be useful if wireless mirroring is unavailable or you prefer a cable-based setup.
Some smartphones support video output through a compatible USB-C adapter or another supported connection.
Steps to Connect Using HDMI
Check whether your smartphone supports wired video output.
Choose a compatible adapter.
Connect the adapter to your smartphone.
Connect an HDMI cable between the adapter and TV.
Turn on the TV and select the correct HDMI input.
Follow any instructions shown on your phone or TV.
Important Compatibility Check
A USB-C port does not automatically mean that a smartphone supports HDMI video output. Check the phone’s specifications and adapter compatibility before purchasing accessories.
Method 4: Connect an iPhone to a Compatible TV
Some iPhones support wireless screen sharing through AirPlay when connected to a compatible TV or supported streaming device.
General Steps
Connect the iPhone and compatible TV or device to the required network.
Open the Control Center on your iPhone.
Tap Screen Mirroring.
Select the compatible TV or device.
Enter a passcode if requested.
The exact process depends on the iPhone model, iOS version, and TV or streaming device.
Screen Mirroring vs Casting: What Is the Difference?
Screen mirroring displays your phone screen on the television. Casting through a compatible app may send supported content directly to the TV or streaming device.
| Feature | Screen Mirroring | App Casting |
|---|---|---|
| Phone screen | Usually displayed | May not be displayed |
| Compatible apps | Not always required | App must support casting |
| Best for | Photos, presentations, supported apps | Videos and music |
| Connection | Depends on device | Depends on app and device |
| Compatibility | Phone and TV support required | App and TV support required |
Both methods can be useful depending on what you want to display.
How to Fix Smartphone-to-TV Connection Problems
Sometimes your phone may not detect the TV or the connection may stop working.
Here are some common solutions.
1. Check Wi-Fi Connection
Make sure the smartphone and TV are connected to the required Wi-Fi network.

Keep your smartphone and TV updated.
Close unnecessary apps if your phone is running slowly.
