There are several proven ways to display an image, each with its own characteristics and hardware requirements. Depending on the model of your Smart TV Depending on your phone's operating system version, connection speeds and video stream quality may vary. We'll review all current options so you can choose the most suitable one for your situation.
For a successful connection, it is critical that both devices are on the same local network. If your router distributes two networks (2.4 GHz and 5 GHz), make sure that your phone and TV are connected to the same frequency. This requirement is fundamental to the operation of most wireless data transmission protocols.
Using Android's built-in Cast feature
Starting with Android 5.0, the system has a native screen mirroring function, which is based on technology MiracastThis method doesn't require installing third-party apps and works on most modern Smart TVs. The steps are simple: pull down the notification shade and find the "Cast," "Smart View," or "Wireless Monitor" button.
Once enabled, the system will begin searching for available devices within Wi-Fi range. When your TV appears in the list, tap it to establish a connection. A confirmation prompt may appear on the TV screen, which you'll need to accept using the remote.

- ✅ Confirm the connection on the TV screen if required.
It's worth noting that image quality when using Miracast directly depends on the strength of your router's Wi-Fi signal. If you experience lag or artifacts, try moving closer to the router or reducing the streaming video quality in your phone's settings.
Setup via Google Home and Chromecast
Owners of TVs with the operating system Android TV or a built-in module Chromecast They can use the official Google Home app to control content. This is one of the most stable methods, ensuring minimal latency and high-resolution images.
To get started, download the Google Home app from the Play Store and sign in to your Google account. Once the app opens, tap the plus sign in the corner of the screen to add a new device and follow the on-screen instructions to pair it.

- 🔗 Make sure the devices are on the same Wi-Fi network.
- 🖥️ Tap "Cast Screen" in the app menu.
What to do if the TV is not located?
If the search yields no results, try rebooting your router. Also, check if AP client isolation mode is enabled on your router, which prevents devices from seeing each other on the network.
It's important to understand that when streaming via Chromecast, your phone acts as a remote control, and the video decoding load falls on the TV. This helps conserve your smartphone's battery and prevent it from overheating.
Apps from TV manufacturers
Major electronics manufacturers often develop their own ecosystems and software solutions for convenient interaction with mobile devices. Using proprietary apps often unlocks additional features unavailable with a standard connection.
For example, there is an application for Samsung equipment SmartThings, which allows you to not only display images but also control TV settings and create smart home scenarios. LG offers a solution LG ThinQ, and Sony - Video & TV SideView.

Comparison of connection methods
To help you choose the best option, we've prepared a comparison table of the main connection methods. It will help you quickly understand the pros and cons of each option depending on your needs.
| Method | Quality | Delay | Complexity |
|---|---|---|---|
| Miracast (Built-in) | High | Low | Low |
| Google Chromecast | Maximum | Minimum | Average |
| Third-party applications | Average | High | Average |
| DLNA (Media server) | High | No (files) | High |
As the table shows, built-in methods or Chromecast are best for watching movies, as they provide the best picture quality. Third-party apps are more of a backup option for specific tasks.
The choice of method also depends on what you plan to view. For static images or presentations, either method is suitable, while dynamic content requires a stable, high-bandwidth connection.
Troubleshooting and troubleshooting
Despite the ease of setup, users may encounter issues such as the TV not detecting the phone or the connection constantly dropping. Most often, the cause lies with the router's security settings or antivirus software.
Check whether a firewall on your phone or router is blocking local connections. Also, make sure your TV's firmware is up to date, as older firmware versions may conflict with newer versions of Android.
⚠️ Warning: Antivirus software on your smartphone may detect screen sharing attempts as suspicious activity and block the connection. Try temporarily disabling protection for diagnostic purposes.
If all else fails, try resetting the network settings on both devices. This will clear the network connection cache and often resolves issues with devices not being visible on the local network.
In rare cases, the problem may be due to Wi-Fi congestion from neighboring networks. Switching your router to a less congested channel in its settings can significantly improve the stability of your video stream.
FAQ: Frequently Asked Questions
Is it possible to broadcast a screen without the Internet, only via Wi-Fi?
Yes, Miracast and most local methods don't require internet access. A router creating a local network to which both devices are connected is sufficient. Some TVs allow you to create a Wi-Fi Direct hotspot, which you can connect to directly from your phone, allowing you to stream content without a router.
Why is there no sound on the TV during broadcasting?
Check the audio settings in the app you're streaming from. Sometimes the phone's audio remains set to default. Also, make sure the TV isn't muted or hasn't selected a different audio source. In some cases, restarting the source app helps.
Does screencasting affect my phone's battery life?
Yes, actively streaming video over Wi-Fi consumes significant power. The phone's screen also remains on, which accelerates battery drain. It's recommended to keep your smartphone charged during extended viewing sessions.
Do all Samsung and LG TVs support this feature?
Almost all modern Smart TV models from Samsung and LG support wireless transmission protocols. However, older models (manufactured before 2014-2015) may not have a built-in Wi-Fi Direct or Miracast module, requiring the use of external adapters.
