Basic requirements and network preparation
Before you begin setup, make sure your router is providing a stable signal. Wi-Fi network It must operate at 5 GHz to transmit high-quality video without lag. If your router is older, you may experience some image lag.
Both devices – the smartphone and the TV – must be connected to the same access point. Using a guest network or different frequencies (2.4 GHz and 5 GHz on different SSIDs) may prevent devices from discovering each other. Check your router settings if the search does not produce any results.
⚠️ Attention: Some corporate networks or public Wi-Fi networks have client isolation (AP Isolation). Under these conditions, devices cannot see each other, even when on the same network. Use a home router.
It's also important to update the software on both devices. Manufacturers frequently release patches that improve protocol stability. Miracast And Google CastGo to system settings and check for updates.
Using the built-in Broadcast feature

It's worth noting that when using this method, your smartphone screen must be unlocked. Any notification or call will be visible to everyone in the room. It's best to use specialized apps for viewing videos.
Google Home app for Chromecast
If your TV has a built-in module Chromecast or you are using an external set-top box, the best solution would be an app Google HomeIt allows you to manage media content and broadcast the entire screen.
Download the app from the store Google Play and log in to your account. The program will automatically find devices on the network. Select your TV from the list of available devices.
In the bottom menu, tap the "Cast my screen" button. Confirm the action, and the content on your smartphone's display will appear on the TV. This method provides a more stable picture than standard Miracast.
What should I do if the broadcast button is grayed out?
If the button is grayed out, check the app permissions. Google Home must have access to the local network and location. Also, make sure your antivirus software isn't blocking the connection.
The advantage of this method is the ability to manage content. You can minimize the app on your phone, and the video will continue playing on your TV. This is convenient for watching movies from cloud storage.
Broadcasting via video hosting applications

| Parameter | Live broadcast (Cast) | Screen mirroring |
|---|---|---|
| Battery consumption | Short | High |
| Video quality | Up to 4K HDR | Depends on Wi-Fi signal |
| Control | You can use the phone | The phone screen is busy |
| Sound notifications | Not broadcast | Heard on TV |
It's important to understand the difference between streaming and screen mirroring. In streaming, the TV downloads the content itself, while in screen mirroring, the phone encodes the video stream and sends it to the TV in real time.
Transfer photos and videos via DLNA
For viewing your personal media library stored in your phone's memory, the technology is ideal DLNAIt allows you to stream files without duplicating the entire operating system interface.
Many modern TVs have a built-in media player. Simply open the "Media," "Gallery," or "Photos" app on your TV. Then, on your smartphone, select a photo or video from the gallery, tap "Share," and select your TV.
If the built-in tools don't work, install a third-party application, for example, BubbleUPnP or AllConnectThese programs scan the network and find all compatible playback devices.
DLNA is convenient because it allows you to create playback queues. You can select hundreds of photos for a slideshow or several movies to watch back-to-back, without having to fiddle with your phone.
Troubleshooting connection issues
Sometimes the pairing process can be problematic. If the TV isn't found, try rebooting the router. Often, the problem lies in a frozen router network module, which stops distributing addresses correctly.
Check if data saving or power saving modes are enabled on your phone. These features can limit background network activity needed for device discovery. Disable them during setup.
⚠️ Attention: Antivirus apps and firewalls on Android can block local connections. If all else fails, try temporarily disabling network protection.
It's also worth paying attention to your date and time settings. If the clocks on your phone and TV are significantly different, security protocols may be preventing the connection. Synchronize the time online.
Comparison of connection methods
Each of the methods discussed has its advantages and disadvantages. The choice depends on what you want to do: play games, watch movies, or present presentations.
Minimal input lag is important for gaming, so it's best to use a wired connection or Miracast with 5 GHz support. For watching movies, a stable stream is more important, which is what Chromecast provides.
Please remember that software is constantly being updated. Application interfaces and menu item names may change. Always consult the latest documentation from your device manufacturer.
Why doesn't the TV see the phone?
Most often, the devices are on different networks. Check that the phone is not connected to mobile data (4G/5G) and the TV is not connected to Wi-Fi. Also, make sure that client isolation is not enabled on the router.
Is it possible to connect a phone to an old TV?
Yes, if you purchase an external set-top box, such as a Chromecast, Mi Box, or Fire TV Stick. They connect via HDMI and add Smart TV functionality to any screen.
Does the connection affect internet speed?
When streaming via Chromecast (using your phone as a remote control), the bandwidth load is minimal. When mirroring your screen, your phone actively transmits data, which can reduce speeds for other devices.
Is it safe to stream personal photos on public Wi-Fi?
No, on public networks, use only secure protocols or a personal hotspot. On open networks, your data can be intercepted by attackers.
How to improve picture quality during broadcasting?
Move closer to the router, close background apps on your phone, and make sure no one else on the network is downloading large files. Use the 5 GHz band.
