Modern smartphones Xiaomi have powerful screens, but watching movies in company or playing games on a big screen often requires displaying the image on a TV SamsungFortunately, modern technology allows you to do this without unnecessary wires, using only your home network. Wi-FiThis not only eliminates cable clutter but also ensures high device mobility.
In this article, we will take a detailed look at all the current broadcast methods built into the shell. MIUI and the ecosystem Android TVYou'll learn how to use standard features, third-party apps, and any issues that may arise when connecting devices from different brands.
The main goal is to ensure a stable connection between the gadget and the TV. To achieve this, both devices must be on the same local network. We'll cover both native tools and more advanced methods that can help if the standard function fails.
Basic requirements and equipment preparation
Before you begin setting up, you need to make sure your equipment is ready for use. A fundamental requirement is the presence of the module. Wi-Fi Both devices must be connected to the same wireless network. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, make sure both devices can see each other and are in the same sub-band.
Televisions Samsung The latest years of production are equipped with an operating system Tizen, which supports protocols Miracast (In Samsung marketing, this is often called Screen Mirroring or Smart View). Smartphones Xiaomi use standard Android with a branded superstructure MIUI, which also has a built-in "Broadcast" feature. For proper operation, both devices must be updated to the latest software version.
It's worth noting that data transfer speed directly depends on the router's signal quality. If you plan to stream high-definition video, 4K HDR, make sure your router supports 802.11ac (Wi-Fi 5) or later, and your TV is connected to a 5 GHz network to avoid lag and buffering.
Using the built-in "Cast" feature in MIUI
The easiest and fastest way, which does not require installing additional software, is to use the system function XiaomiIn the shell MIUI It's called "Broadcast" or "Cast". This method is based on the protocol Miracast, which is “sharpened” for direct connection of the phone screen and TV.
To begin the process, unlock your smartphone and pull down the notification shade. Look for the icon labeled "Broadcast" (sometimes it's hidden in an additional menu that opens with a swipe to the left). If you don't see the icon, go to Settings → Connection and Sharing → BroadcastThe system will automatically start searching for available devices on the network.
On TV Samsung You need to activate connection standby mode. Usually, it's enough to press the button Source on the remote control and select the item Screen Mirroring or Smart ViewIn some newer models, this feature is enabled by default and does not require manual activation; the TV simply becomes visible for searching.
⚠️ Note: On some versions MIUI The function may be called "Wireless Monitor" or "Wireless Display." If searching doesn't yield any results, try restarting the Wi-Fi module on both devices.
Once the phone detects your Samsung TV, tap its name in the list. A permission request may appear on the TV screen—confirm it with the remote. The image from your phone will instantly appear on the big screen. To disconnect, simply tap the "Stop" button in the control widget on your smartphone.
Broadcast via the Google Home app
If the native function Xiaomi If your TV isn't working properly or isn't finding your TV, the official app is a great solution. Google HomeIt allows you to broadcast not only the content of individual applications, but also completely duplicate the smartphone screen using the infrastructure Chromecast built-in, which is built into most modern Smart TV.
Download and install the application Google Home from the store Play MarketLaunch it and sign in to your Google account. The app will automatically scan the network and find connected smart devices, including your TV. SamsungMake sure the function is enabled on your TV. Chromecast (It is usually active by default in the General Settings menu).
Select your TV from the list of devices. In the control menu that opens, press the button. Broadcast your screen (Cast my screen). The system will warn you that the audio and video will be transmitted to the TV. Confirm the action, and the dubbing will begin.
☑️ Check before connection
The advantage of this method is its high stability and support for a wide range of formats. However, it's important to note that it's controlled only from your phone: locking your smartphone's screen or minimizing the app may interrupt the stream, unlike with some other methods.
Alternative apps: AirScreen and others
In cases where standard protocols Miracast And Chromecast If they don't provide the desired results or are missing from older TV models, third-party solutions come to the rescue. One of the most popular is the app AirScreen For Android TV, which emulates various data transfer protocols.
Install the application AirScreen directly to TV Samsung through the app store Tizen Store (if available) or, more likely for this program, use Android TV Box, connected to the TV. If you have exactly Smart TV from Samsung with the Tizen system, look for similar ones, such as TV Cast or Smart View (official Samsung app for mobile, although it is more for control).
For the bunch Xiaomi + Samsung Often the combination works effectively: application Web Video Caster on the phone and its receiver on the TV, or using the built-in browser Samsung to receive streams. But if we're talking specifically about screen mirroring (Mirror), then a receiver must be running on the TV side. AirPlay or Miracast.
Why might the broadcast not work?
The problem may be with your router settings. Some routers have a feature called "AP Isolation," which prevents devices within the same Wi-Fi network from communicating with each other. Disable this feature in your router settings (usually in the Wireless Settings section) so your phone can see your TV.
If you are using a prefix Android TV (For example, Xiaomi Mi Box or Nvidia Shield), connected to a Samsung TV, then installation AirScreen to the set-top box will turn it into a universal receiver. In this case, the phone Xiaomi will see the set-top box as a standard device for broadcasting.
Media Streaming (DLNA) vs. Screen Mirroring
It's important to distinguish between two concepts: full screen mirroring (Mirror/Cast) and media streaming (DLNA). The first method copies everything that's happening on your phone's display, including notifications and the home screen. The second method is designed exclusively for playing videos, photos, or music stored on your phone directly on your TV.
For DLNA, you don't need to mirror your screen. Just open your gallery or video player on Xiaomi, select the file and click the "Broadcast" button (the rectangle icon with Wi-Fi waves). TV Samsung will act as a renderer. This significantly reduces the load on the phone's processor and saves battery life.
Below is a table comparing the main characteristics of the connection methods:
| Characteristic | Screen Mirroring (Miracast) | Google Cast (Chromecast) | DLNA (Media) |
|---|---|---|---|
| What is transmitted | Full phone screen | Browser tab or screen | Only the selected file |
| Phone addiction | High (screen should be lit) | Medium (you can use other apps) | Low (you can turn off the screen) |
| Image quality | Depends on Wi-Fi signal | High (adaptive) | Original (uncompressed) |
| Sound | Transmitted with or without delay | Synchronized | Perfect synchronization |
The choice of method depends on your goals. It's better suited for demonstrating presentations or games. MiracastTo watch downloaded movies in high bitrate - DLNAFor streaming from online services (YouTube, Netflix), it is best to use the built-in broadcast button within the application itself, which is essentially a variation Google Cast.
Solving delays and quality issues
When transmitting wireless data, problems with audio and video lip-sync or image stuttering often occur. The main cause is air traffic congestion or a weak signal. Try moving the router closer to the viewing area or using Wi-Fi repeater to boost the signal in the living room.
Another important aspect is resolution. If the phone Xiaomi If you're trying to stream a 4K image and your bandwidth is limited, you'll experience lag. In the streaming settings (if available in the app you're using), try lowering the resolution to 1080p or 720pThis often makes the picture smoother.
Also, check that there are no background downloads or app updates running on your phone. These can clog up your bandwidth and interrupt the video stream. Close unnecessary apps before starting your session.
Frequently Asked Questions (FAQ)
Is it possible to display a screen directly without a router?
Yes, technology Wi-Fi DirectMiracast, the underlying technology, allows a phone and TV to connect directly, bypassing a router. However, a local network is often required for the initial handshake and DRM license verification. Try selecting "Direct Connection" in your phone's casting menu if a router is unavailable.
Why is there video streaming but no sound?
This is a common codec issue. Some audio formats (such as Dolby Digital Plus) may not be supported by your TV when streaming from your phone via Miracast. Try changing the audio settings in the app you're streaming from to stereo (PCM), or use the DLNA method, which often bypasses these limitations.
My Samsung TV can't detect my Xiaomi phone. What should I do?
Make sure Guest Network mode or client isolation aren't enabled on your TV. Also, check the date and time on both devices—time misalignment can block the connection. Restarting the router often resolves the issue of devices not being visible.
Does broadcasting affect internet speed?
Yes, when mirroring your screen (Miracast), the traffic flows within the local network and shouldn't significantly impact internet speeds for other devices if your router is powerful. However, when using Google Cast (cloud streaming), the TV downloads the content itself, consuming your internet bandwidth.
Is it possible to play games from your phone on your TV via Wi-Fi?
Technically, it's possible, but input lag over a wireless connection can be 100 ms or higher. This is acceptable for turn-based strategy or card games, but shooters or racing games will require a wired connection or using your TV's game mode to minimize lag.
