Modern ecosystems often force users to look for workarounds to synchronize devices from different manufacturers. The owner of a Samsung smartphone who bought a Xiaomi TV may find that the usual features do not work out of the box as they would with the same type of technology.
In fact, there are several proven and reliable ways to stream images and sound from a mobile device to a big screen, whether it's viewing photos, presenting work documents, or launching a movie from an online cinema, you can enjoy high-resolution content. Below we'll take a look at all the methods available, including wireless protocols and wired connection.
You don't need a deep knowledge of networking to synchronize successfully, but you need to follow the step-by-step instructions to turn your Smart TV into a multimedia center managed from a phone, and we'll look at both the built-in tools of the Android operating system and the specialized applications from Google.
Preparation of equipment and network
The first and most critical step is to ensure the right network infrastructure: For most wireless broadcast methods, such as Miracast or Google Cast, both devices must be on the same LAN, which means that both Samsung and Xiaomi TVs must be connected to the same router.
Pay attention to the frequency of Wi-Fi connection. If your router supports dual-band operation, it is recommended to use a 5 GHz network. It provides higher bandwidth, which is critical for transmitting a video stream in high resolution without delays and artifacts.
⚠️ Note: If one of the devices is connected to a guest Wi-Fi network or uses mobile Internet (4G/5G), The local network will not work, make sure that the router settings do not activate customer isolation.
It’s also worth checking the software’s relevance: On a Xiaomi TV running Android TV or PatchWall, you may need to update system components to properly operate device discovery protocols.
☑️ Checking before connection
Use of the built-in Smart View function
The easiest and fastest way to do this without needing to install any additional software is to use Samsung’s One UI technology, which is based on the Miracast standard, which is supported by most modern TVs, including Xiaomi models.
To start the broadcast, lower the notification curtain on your smartphone and find the Smart View icon. If it is not on the main panel screen, flip to the right or click on three points to edit the list. Once activated, the system will start searching for available displays in range.
When your Xiaomi TV appears on the list, tap its name. The TV screen may have a request for confirmation of connection, which must be received using the remote control, and then the image from the phone will be duplicated on the large screen in real time.
- 📱 Open the Quick Settings Panel on Samsung.
- 🔍 Click on the Smart View icon.
- 📺 Select a Xiaomi TV from the list of found devices.
- ✅ Confirm the connection on the TV screen if required.
It's important to understand that Miracast is the mirroring of the screen, which means that all the notifications, calls and actions you make on your phone will be visible on the TV. It's not always convenient for watching videos, since the phone's interface can overlap part of the image or have black stripes on the sides.
💡
During the Smart View broadcast, you can flip the phone horizontally so that the image takes up the entire TV screen if the content requires it.
Broadcasting via Google Home and Chromecast
A more advanced and high-quality method is the use of Google Cast technology (Chromecast built-in). Xiaomi TVs run on the Android TV operating system, so support for this protocol is built natively. To manage the process on the Samsung phone, you will need the Google Home application.
Download and install the Google Home app from the Google Play store. Once installed, open the app and log in to your Google account. The system will automatically scan the network and find connected smart devices, including your TV.
In the app interface, find your Xiaomi TV card. Click on it to open the control panel. At the bottom of the screen, you'll see the Cast My Screen button. Clicking on it will trigger the mirroring process using Google codecs, which often provides lower latency and better picture quality than a standard Miracast.
| Characteristics | Smart View (Miracast) | Google Home (Chromecast) |
|---|---|---|
| Installation of applications | Not required | Google Home is required |
| Image quality | Depends on the Wi-Fi signal. | Optimized by Google |
| Working in the background | Phone screen is active | You can use the phone. |
| Compatibility | Tall. | Only Android and iOS |
The thing about Google Home is that you can run a video and then you can turn the app down, or you can turn off the phone screen, and you can continue to play on the TV, and that's what distinguishes this from just mirroring.
Broadcast from YouTube and Netflix apps
Special attention should be paid to the broadcast of content from popular video services: in the applications YouTube, Netflix, IVi and others on the Samsung smartphone implemented its own function Cast. It works most stable and allows the phone to act as a remote control, without loading its processor with decoding video.
To run, open an app like YouTube on your phone. In the upper right corner or in the corner of the video player, find the broadcast icon (a rectangle with waves in the corner). Click on it and select your Xiaomi TV from the list.
Unlike DSLR, here the video is downloaded directly from the Internet by the TV, which means that the image quality will be maximum (up to 4K HDR), and the battery of the phone will be spent minimally, you can respond to messages or play games without interrupting the viewing on the big screen.
⚠️ Note: Google accounts on your phone and TV must be authorized to stream from apps, although it is often enough to be on the same Wi-Fi network without strictly linking YouTube accounts.
If the broadcast icon doesn't appear or is grey, check if a VPN is being used on the phone.Video streaming services often block the detection of Cast devices if they see traffic coming through a virtual tunnel.
What if the app doesn’t see the TV?
Connecting via HDMI adapter
In situations where the wireless network is overloaded or maximum stability is required (for example, for gaming or showing important data), it is better to use a wired connection. Samsung mid- and flagship-level smartphones support image output via a USB Type-C port using the MHL or DisplayPort Alt Mode standard.
To implement this method, you will need a special USB-C to HDMI adapter. One end of the adapter connects to the smartphone, and the second inserts a regular HDMI cable that goes to the Xiaomi TV.
On the TV remote, click the signal source selection button (often designated as SOURCE or the arrow square icon) and select the appropriate HDMI port. The image from the phone will appear instantly, without delays and compression artifacts.
- 🔌 Buy a quality adapter USB-C on HDMI.
- 📺 Connect the cable. HDMI Xiaomi TV.
- 📱 Connect the adapter to a Samsung smartphone.
- ⚙️ Switch the signal source to the desired TV HDMI.
Some budget Samsung smartphones may not support video output via USB, in which case the adapter will only work for charging or transferring files, but the picture will not appear on the screen.
💡
Wired connectivity ensures no delays (input lag), making it the only viable option for cloud gaming or dynamic games on the big screen.
Solving Connection Problems and Errors
Despite the ease of setting up, users may face a variety of difficulties, and one of the most common problems is when the phone simply “does not see” the TV in the list of available devices, most often due to settings on the network screen or router firewall.
Try rebooting both devices. Turn off the Xiaomi TV completely (pull the cord out of the socket for 10 seconds), rather than just putting it in standby mode. On a Samsung phone, reboot or just reconnect to the Wi-Fi network.
Another problem is the de-synchronization of sound and video, and if you notice that actors' lips don't get into the beat of speech, try lowering the quality of the broadcast in the app settings or bringing the router closer to the TV, and interference from microwave ovens and bluetooth headsets can also affect flow stability.
