Modern Samsung smartphones have turned into powerful multimedia centers capable of storing thousands of movies, TV series and personal videos in high definition. However, enjoying content on the small screen of a mobile device is not always convenient, especially when you want to share the viewing with your family or just immerse yourself in the atmosphere of the cinema. Fortunately, the ecosystem Android and wireless technologies make it easy to transfer images to the big screen without unnecessary wires.
The process of screen mirroring or streaming media has become much easier thanks to the standardization of data transfer protocols. You won't need complex adapters or HDMI cables if both devices support the same network. In this article, we will analyze in detail all the available ways to connect your Samsung smartphone to a TV, from built-in system functions to specialized software.
Before you start setting up, you need to make sure that your equipment is technically ready for interaction. The basic operating principle of all the methods under consideration is based on a local network WiFi, so the stability of the connection plays a critical role. Let's take a detailed look at the requirements and preparatory steps that guarantee successful synchronization of devices.
Preparing equipment and network for broadcast
The foundation for successful wireless video transmission is the correct configuration of your home network. Both devices - your phone Samsung Galaxy and the TV - must be connected to the same router. This is a prerequisite, since device discovery protocols, such as DLNA and Miracast, work exclusively within the same subnet.
If your router supports dual-band operation, it is strongly recommended to use the frequency 5 GHz. This range provides higher throughput, which is critical for transmitting video in 4K or Full HD resolution without delays or compression artifacts. The frequency 2.4 GHz can be overloaded by neighboring networks and household appliances, which will lead to slowdown of the picture.
It is also worth checking that the software on both devices is up to date. Manufacturers regularly release updates to fix bugs in the wireless protocol stack and improve compatibility. On a TV, this is usually a section Settings → Support → Software Update, and on a smartphone the path goes through Settings → Software Update.
⚠️ Attention: Some older TV models may not support modern WiFi encryption standards. If the TV does not see the network, try temporarily disabling password protection for verification or creating a guest network on the router without complex security protocols.
Make sure that the function for receiving external signals is activated on the TV. Depending on the brand and model, this option may be called differently: Screen Share, Wireless display or Input Source. Without an active receiving service, the smartphone simply will not be able to detect the target device in the list of available connections.
Using the built-in Smart View function
The simplest and most integrated way to display an image from a Samsung phone on the TV screen is to use a proprietary utility Smart View. This technology was developed specifically for devices of the South Korean brand and provides the best compatibility with Samsung TVs, although it also works with other brands that support the Miracast protocol.
You do not need to download third-party applications to run the function. Just unlock your smartphone and swipe the quick settings panel from top to bottom. Among the icons you will find an icon Smart Viewthat looks like a playback triangle surrounded by two arcs. Clicking on it initiates a search for available displays within WiFi range.
Once the list of devices appears on your phone screen, select your TV. The connection establishment process can take from a few seconds to a minute, depending on the network response speed. A request to confirm the connection may appear on the TV screen, which must be accepted using the remote control.
☑️ Check before connecting Smart View
After successful pairing, the image from the smartphone screen will be completely duplicated on the TV. You can control video playback, scroll through photos, or even play games using your phone as a controller.
If the picture quality is low, go to the Smart View settings (three dots in the menu) and change the transmission resolution to a higher one if your network allows it.
Broadcast via Google Chromecast and applications
If your TV is not a Samsung device or built-in the function does not work correctly, the technology Google Cast (Chromecast built-in) will be a universal solution. This technology is built into most modern TVs, as well as models from Sony, Philips, TCL and other manufacturers. Unlike mirroring the entire screen, Chromecast allows you to stream a specific video stream directly from an application to your TV. This means that the phone only acts as a control panel, and the video is downloaded by the TV directly from the Internet, which saves battery power and relieves the WiFi channel from duplicating the system interface. Android TV, as well as models from Sony, Philips, TCL and other manufacturers.
Unlike mirroring the entire screen, Chromecast allows you to cast a specific video stream directly from an app to your TV. This means that the phone only acts as a control panel, and the video is downloaded by the TV directly from the Internet, which saves battery power and relieves the WiFi channel from duplicating the system interface.
To use this method, make sure that Google Play services are installed on your smartphone, which are present by default on all certified Samsung devices. Open an application that supports broadcasting, for example YouTube, Netflix or VK Video, and find the broadcast icon - a rectangle with WiFi waves in the corner.
| Comparison parameter | Smart View (Miracast) | Google Cast (Chromecast) | DLNA Players |
|---|---|---|---|
| Transmission type | Screen mirror | Streaming video | File broadcast |
| Phone dependence | High (screen lit) | Low (remote control only) | Medium |
| Game support | Yes | No | No |
| Picture quality | Depends on the signal | Maximum (up to 4K) | Original file |
When you click on the broadcast icon, the application will prompt you to select the target device. Once selected, the video will start playing on the big screen, and a control panel will appear on the phone with buttons for pause, rewind, and volume control. You can minimize the app or even lock your phone and playback will not be interrupted.
Viewing local files via DLNA servers
A situation often arises when a video file is saved in the phone’s memory, but not uploaded to the cloud or streaming service. In such cases, technology DLNA (Digital Living Network Alliance) comes to the rescue. It allows you to organize a media server directly on your smartphone, to which the TV will connect as a client.
To implement this scheme, you will need to install a special server application from the store Google Play. Popular options include BubbleUPnP, LocalCast or Skifta. After installation, the application will scan the device memory and create a list of media files available for streaming.
Launch the selected application and allow access to the storage. Then, in the app interface, select the "Devices" or "Renderer" tab and find your TV. Once connected, just select a video file from the list and it will start playing on the TV screen.
⚠️ Attention: When using DLNA, make sure that the video file format is supported by the TV. If the TV does not have a built-in codec for a specific container (for example, MKV with a rare audio codec), playback may not start, despite a successful connection.
The advantage of this method is the ability to play content without access to the Internet, since data transfer occurs locally within your network. This is ideal for watching family archives or movies downloaded on the road when you return home.
What to do if the TV does not see files?
Make sure that the “AP Isolation” function is not activated in the router settings. This feature prevents devices within the same WiFi network from communicating with each other, which blocks DLNA.
Solving problems with delays and image quality
Despite the convenience of wireless technologies, users often encounter desynchronization of sound and image or periodic picture freezes. The main culprit for such problems is almost always an unstable radio channel or insufficient network bandwidth.
Try rebooting the router by unplugging it for 10-15 seconds. This will clear the device's cache and allow it to select the least busy channel to operate on. It is also recommended to close background applications on your smartphone that may consume traffic, such as torrent clients or cloud synchronizers.
If you use screen mirroring, try lowering the output resolution in your phone settings. Switching from 1080p to 720p can significantly reduce the load on the communication channel and eliminate lags, making viewing smoother, albeit with less detail.
The stability of the connection directly depends on the distance to the router and the number of physical obstacles (walls) between devices.
B In cases where the wireless connection remains unsatisfactory, it is worth considering alternative options. For example, using a WiFi adapter that connects directly to the TV's USB port (if the model supports it) can improve signal reception. There are also external set-top boxes, such as Chromecast or Apple TV, which have more powerful antennas than the built-in modules of older TVs.
Third-party applications for specific tasks
Sometimes standard tools are not enough, especially if you need to stream content from applications that block the function Cast (for example, some browsers or secure video players). In such situations, universal translators come to the rescue.
The application Web Video Caster is one of the leaders in this niche. It allows you to enter a video stream URL or find a video in the built-in browser and send it to your TV, bypassing some software restrictions. The application automatically selects the optimal transmission protocol for a specific TV model.
Another powerful tool is AirScreen (if we are talking about reception on Android TV) or analogues for transmission. These apps emulate the AirPlay, Miracast and Google Cast protocols, making your TV visible to devices that were not originally designed to work with it.
When installing third-party software, carefully read the permissions that the application requests. For video broadcasting to work correctly, the app requires access to the local network and, in some cases, the right to display on top of other windows (overlay permission).
⚠️ Attention: Application interfaces and menu names may differ depending on the firmware version of your TV and Samsung smartphone model. If you do not find the described option, use the settings search or refer to the manufacturer's official documentation.
Frequently asked questions (FAQ)
Why doesn’t a Samsung phone see the TV in the list of devices?
The most common reason is devices connected to different WiFi networks (for example, one to the guest network, the other to the main one). Also check to see if client isolation is enabled on your router. Make sure your TV is running an application to receive the signal or the appropriate input source is selected.
Can you watch video with your phone screen turned off?
When using Smart View (mirroring), the phone screen must be turned on, otherwise the transmission will stop. However, when using Google Cast technology (via the icon in the YouTube, Netflix, etc. applications), the phone works as a remote control, and the screen can be turned off - the video will continue to play on the TV.
Does broadcasting affect the Internet speed for other devices?
Yes, wireless video transmission, especially in high definition, consumes a significant part of the WiFi channel bandwidth. If your Internet channel is narrow, other network users may notice slower page loading speeds or buffering of online videos.
How to disable video streaming?
To disable Smart View, open the quick settings panel again and click on the active icon, selecting "Disable". To stop the Cast broadcast, click on the cast icon in the application on your phone and select "Stop broadcast" or simply close the application.
Does my old TV support wireless casting?
If the TV does not have a built-in Smart TV or the support is outdated, you can purchase an external adapter such as Google Chromecast, MiraScreen or an Android TV set-top box. They connect to the HDMI port and add wireless reception functionality to any device with a video input.
