Modern multimedia systems make it easy to stream content from a smartphone to a big screen, but owners of Xiaomi equipment and Telefunken TVs sometimes face the nuances of pairing. The main difficulty often lies not in the lack of a function, but in choosing the right data protocol, whether it is a standard Miracast or proprietary solutions of the manufacturer. It is extremely important for a successful connection that both devices are on the same local network, which is a basic but often ignored requirement.
Depending on your Telefunken TV model, it can run on Android TV or have its own private operating system with Smart TV support. In the first case, the process is as simple as possible thanks to built-in support for Google Cast, in the second case, you may need to use third-party intermediary applications. We will look at all the available methods, from wireless technologies to wired connection via HDMI, so you can choose the most suitable option for your situation.
Connection stability is directly dependent on the quality of the Wi-Fi signal and the version of the software installed on the gadget. Before you start setting up, make sure that your Xiaomi smartphone has the current version of the MIUI or HyperOS shell installed, as updates often fix errors of the wireless module. Below are detailed instructions to help you enjoy photos, videos and games on the big screen without delay.
Wireless connection via built-in MIUI functionality
The easiest way to display an image is to use the built-in broadcast feature, which is called Translation or Cast on Xiaomi smartphones, which is based on the Miracast protocol, which is supported by most modern TVs, including many Telefunken models with Screen Mirroring function. You do not need to install additional apps if your TV is on the list of available devices.
To activate, open the control center on your smartphone by swiping from top to bottom, and find the Translation icon. If it's not on the home screen, click on a pencil or edit button in the corner to add a widget to the active area. Once you turn on the search, the phone will start scanning the environment for compatible signal receivers.
When the name of your TV Telefunken appears on the screen, just tap it. The TV itself may have a request for permission to connect, which must be confirmed by the remote control. It is worth noting that when using this method, the image from the phone is duplicated one by one, so the resolution of the TV screen can be adapted to the format of the smartphone.
💡
If the TV is not found, try manually enabling Screen Mirroring or Wireless Monitor in the settings menu of the Telefunken TV itself via the remote.
The quality of the video stream depends on the load of the wireless channel. If you see a desynchronization of sound and video or twitching pictures, try to zoom in on the router or use the 5 GHz band if your router and TV support this frequency.
Using Google Chromecast technology in Android TV
Many of today’s Telefunken models run Android TV, which opens up access to native Google Cast technology. Unlike mirror display, this method allows you to stream content directly from apps like YouTube, Netflix or Kinopoisk, using the phone only as a remote control, which significantly unloads the smartphone processor and saves battery life.
To start the broadcast, make sure that the apps on your phone and TV are updated to the latest version. Open the video or photo you want to show, and find the characteristic wave rectangle icon in the corner of the app interface.
Select your Telefunken from the list, and playback will start automatically, and the advantage of this method is that you can fold the app or even lock your phone, and the video on the TV will continue to go. This is perfect for long-term movie watching.
It's important to understand the difference between Miracast and Chromecast, which is that the first method duplicates the entire screen of a smartphone, while the second method sends a link to content to a TV that downloads it itself from the Internet, so to work Google Cast, a TV must have access to the network, not just be on the same local network with the phone.
Intermediaries for Smart TVs without Android
If your Telefunken TV is smart but not Android-based, Xiaomi’s regular tools may not see it, and in such cases, universal broadcasting apps that are installed on your smartphone come to the rescue, with TV Cast, Web Video Caster or BubbleUPnP being the leaders in this niche.
The principle of operation of such utilities is emulation. DLNA-server or protocol DIAL. You need to download the selected app from Google Play Market to your phone and, if required, the corresponding receiver app to your TV (often available in the app store). TV). After starting, the program will scan the network and suggest connecting the device.
Special attention should be paid to access rights. When you first run the application will ask permission to access the local network and media files. Without these rights, you will not be able to scan the network and you will not be able to find your TV.
☑️ Checking before connection
Some apps allow you to stream not only video files, but also the content of the browser. This is convenient if the desired video service does not have an official application on the TV, but is available through the web interface on the smartphone.
Wired connection via HDMI and adapters
For those who require maximum image quality without compression and delay, wired connectivity remains the best solution. Since Xiaomi smartphones do not have an HDMI port, you will need a special USB-C to HDMI adapter. It is important to note that not all phone models support video output via USB.
Video output support is typically available on flagship and mid-budget models with a USB 3.0 port or higher, as well as devices with DisplayPort Alt Mode technology. Budget models with USB 2.0 are most often devoid of this feature, and the adapter will only work for charging or data transfer, but not video.
To connect, connect the adapter to your phone, insert the HDMI cable into the adapter and TV, then switch the TV signal source to the appropriate port, such as HDMI 1 or HDMI 2.
| Type of connection | Image quality | Delay (Latency) | Dependence on Wi-Fi |
|---|---|---|---|
| Miracast (Translation) | High (compression) | Medium | Tall. |
| Google Cast | Maximum. | Low. | Medium (start only) |
| USB-C to HDMI | No loss (Lossless) | Minimum | No. |
| DLNA (Players) | High. | Low. | Medium |
⚠️ Note: When using cheap adapters HDMI The image may blink or be absent due to lack of power.
If the image appears but the sound is coming from the phone, go to the sound settings and select the output to the external device. In some cases, you need to manually select the resolution in the settings of the smartphone screen, if the TV does not determine it automatically.
Broadcasting through DLNA-server
DLNA is a time-tested standard for sharing media on a local network, allowing you to stream files (video, music, photos) that you have downloaded to your phone directly to your TV using its built-in media player. To do this, you need to install a server application on your Xiaomi smartphone, such as BubbleUPnP, or use the built-in functionality of some file managers.
Launch the app, select a video file, and click the "Cast" button. From the device list, select your Telefunken. The TV will receive the data stream and play it on its own, which takes the load off the phone's processor and allows it to be used for other tasks.
The main advantage of DLNA is the ability to play heavy high-resolution files that can slow down when wirelessly mirroring the screen, but the most convenient way to manage rewinding or selecting files is from a phone, which in this case acts as a remote control.
Why can't DLNA see the files?
Remember, DLNA doesn't support mirroring system interfaces or games, it's just a file protocol for static content, and if you want to show the game interface or chat in a messenger, this is not a good way to do it.
Solving Typical Connection Problems
Despite the standardization of processes, users often find that Telefunken TV does not see Xiaomi phone or the connection is constantly broken.One of the most common reasons is the separation of networks by the router. Make sure that both devices are connected to the same SSID and, critically, to the same frequency (for example, both to 2.4 GHz or both to 5 GHz), although modern routers must correctly route traffic between frequencies.
Another reason may be activated “Incognito” mode in the phone’s Wi-Fi settings or privacy settings. MAC-In some cases, antiviruses or firewalls on the router block local device detection (Multicast traffic.
If the problem is only in certain applications, check their permissions, for example, YouTube must have access to the local network, and rebooting the Wi-Fi module on your phone helps: turn on and off Flight Reim.
⚠️ Note: If after the firmware update MIUI The broadcast stopped working, reset the network settings in the “Connections and Sharing” menu» → «Reset Wi-Fi, mobile networks and Bluetooth».
If nothing helps, you can try static settings. IP-address or use of Wi-Fi Direct, if such an option is supported by a particular TV model, but this requires a deeper knowledge of network settings.
💡
90% of connection problems are solved by restarting the router and checking that the phone and TV are on the same subnet.
