Modern smartphones, including popular models Realme, have become powerful multimedia centers capable of storing huge libraries of photos and high-resolution videos. However, viewing content on a small screen isn't always enjoyable, especially when you want to share it with family or friends. This is when it becomes necessary to stream content from a mobile device to a large TV screen using wireless networking.
Fortunately, the Android operating system on which the shell is based Realme UI, offers several built-in mechanisms for transmitting video signals without the need for additional cables. Wireless data transmission technologies enable a stable connection between a gadget and a smart TV, ensuring high-quality image transmission. In this article, we'll cover all available methods in detail, from standard system functions to specialized apps.
You don't need to be a network expert to set up streaming. Modern interfaces are as simple and intuitive as possible. All you need is for both devices to be on the same local network, and you can enjoy your favorite movies or presentations on the big screen, leveraging the full potential of your smartphone.
Preparing equipment and a Wi-Fi network
Before you begin setting up your broadcast, you need to make sure your equipment is ready to go. The first and most important requirement is a stable wireless connection. Both devices—a smartphone Realme and your TV must be connected to the same Wi-Fi network. If you have a dual-band router, make sure the devices are connected to the same frequency, although modern routers often combine bands into a single network.
Check the software version on your TV. Many manufacturers, such as Samsung, LG or Sony, regularly release updates that improve protocol compatibility Miracast And DLNAOn Smart TVs, the signal reception function is often built in by default, but may be called by different names: Screen Share, Smart View, Mirroring, or Wireless Display.
It's also worth paying attention to your smartphone's battery life. Wireless video streaming consumes a significant amount of power. If you plan on watching for a long time, it's best to connect your phone to a charger to avoid a sudden power outage at the most inopportune moment.
⚠️ Note: If your router is configured to separate clients (AP Isolation), devices may not be able to see each other on the network. In this case, you need to go to the router settings and disable this feature for the local network.
Using the built-in Cast feature in Realme UI
In smartphones Realme With Realme UI, wireless display is built right into the system. This is the easiest and fastest way to do this, requiring no third-party software. The technology used here is based on the standard. Miracast, which allows you to transmit video and audio in real time with minimal delay.
To activate the mode, unlock your phone and swipe down on the notification shade. In the quick access panel, look for the icon labeled "Broadcast." If you don't see it in the first row, you may need to switch to the second page or tap the edit button to add this control.
Once the feature is activated, your phone will begin searching for available devices on the network. At this point, a connection confirmation request may appear on the TV screen. You will need to select your Realme from the list of found devices on the TV remote control or confirm the connection by pressing the button on the TV screen. Once paired successfully, your phone's screen will be mirrored on the large display.
☑️ Pre-broadcast check
It's worth noting that image quality directly depends on the strength of the Wi-Fi signal. If the router is located far away or the signal is overloaded by neighboring networks, you may experience choppy images or out-of-sync audio. In such cases, it's recommended to move the router closer to the viewing area or use a repeater to boost the signal.
Broadcast via the Google Home app
If the built-in feature doesn't work for some reason, or your TV better supports the Google ecosystem, the official app is a great solution. Google HomeThis method is especially relevant for TVs with an operating system Android TV or built-in support Chromecast.
To get started, you need to download the application. Google Home from the store Play Market, if it is not already installed on your device RealmeAfter installation, launch the app and sign in to your Google account. The program will automatically scan the network and find all compatible devices, including smart speakers, TVs, and media players.
Find your TV in the list and tap its icon. In the control menu that opens, select "Cast screen." Your phone will warn you that notifications and sounds may be heard on the TV during the cast. Confirm the action, and the image will appear on the screen.
| Method | Delay | Quality | Compatibility |
|---|---|---|---|
| Built-in broadcast | Low | High | Universal (Miracast) |
| Google Home | Average | Very high | Android TV / Chromecast |
| Applications (DLNA) | Absent | Depends on the file | File media libraries |
| HDMI cable | Absent | Maximum | Availability of Type-C port |
Advantage of using Google Home lies in the ability to broadcast not only the screen, but also content from specific applications that support the protocol Chromecast built-inThis allows you to use your phone as a remote control without draining its battery on image rendering, as the stream is sent directly from the internet to your TV.
What to do if the TV is not found?
If the search yields no results, try rebooting your router. Also, make sure there are no heavy apps running on your TV that could be blocking new connections. In rare cases, temporarily disabling mobile data on your phone to force the system to use only Wi-Fi may help.
Using proxy apps and DLNA
When it comes to playing specific video files stored on your phone's memory or streams from services that don't support standard protocols, specialized apps come to the rescue. The leaders in this niche are Web Video Caster, BubbleUPnP and a built-in player Google PhotosThese programs use the protocol DLNA for transferring media files.
The principle here is different from screen mirroring. You select a video file in the app on your phone and then specify the output device. The phone sends only a link to the file or the data stream itself to the TV, and the TV handles the decoding. This significantly reduces the load on the smartphone's processor and allows you to watch the video in its original quality without compression artifacts.
The application deserves special attention Web Video CasterIt's unique in that it can extract video streams from browser pages. If you're watching a movie on a website in a browser, Realme, you can press the cast button in the app plugin, and the video will open on the TV while your phone acts as a remote.
⚠️ Warning: When using third-party apps to stream videos from untrusted sources, make sure your antivirus is active. Some streaming services may attempt to inject advertising scripts into the playback process.
It's important to understand the difference between screen mirroring and media file sharing. In the former case (Miracast), the phone encodes the image in real time, which can cause the device to heat up. In the latter case (DLNA/Chromecast), the phone acts only as a controller, which is much more energy efficient.
Solution: Delays and connection drops
Even with a perfect setup, users may encounter technical issues. The most common ones are audio and video desynchronization or intermittent image freezing. This almost always indicates Wi-Fi bandwidth issues or signal interference.
Try switching your router to a less crowded channel. In apartment buildings, the 2.4 GHz band is often overcrowded, leading to packet loss. If your router and TV support the band, 5 GHz, be sure to use it. It provides higher data transfer rates, which is critical for 4K video.
It's also worth checking if there are any heavy downloads or app updates running in the background of your phone. Operating system Realme UI may limit background activity, but sometimes processes still consume bandwidth, competing with the video stream. Close unnecessary browser tabs and stop downloads before watching.
Alternative connection options
If a wireless Wi-Fi connection isn't possible due to a weak signal or technical limitations of an older TV, there are always tried-and-true wired methods. For modern smartphones Realme with port Type-C There are special Type-C to HDMI adapters.
This adapter allows you to connect directly to your TV using a standard HDMI cable. The phone then detects the external connection and displays the image in its native resolution. This is ideal for gamers, as input lag is minimal with a wired connection.
However, it's worth keeping in mind that not all Realme models support USB video output. This feature is typically found in flagship series. Budget models may require special docking stations with DisplayLink technology, which utilize software-based video compression.
Why does the TV say "No signal" when I try to connect?
Most often, the problem is that the TV isn't switched to the correct signal source (HDMI or Screen Mirroring). Also, make sure both devices are on the same subnet. If the router is sharing a network with guests, they may be isolated from the main network where the TV is located.
Is it possible to display Realme screen on TV without Smart TV?
Yes, you'll need a special set-top box, such as a Google Chromecast, Xiaomi Mi Stick, or any Android Box. These devices connect to the HDMI port of a regular TV and add Smart TV functionality, allowing you to receive a signal from your phone.
Does broadcasting affect the image quality of the source file?
When using Miracast protocols, the video stream is compressed in real time, which may slightly reduce detail. When using DLNA or Chromecast to play files, the original quality is preserved, as the file is decoded by the TV itself.
How do I turn off the broadcast?
To stop streaming using the built-in feature, pull down the notification shade and tap "Stop" or "Disconnect." In apps like YouTube or Google Home, simply tap the streaming icon and select "Stop." You can also simply turn off your phone's screen or disconnect from the Wi-Fi settings.
