You try to stream a Samsung screen to a Xiaomi TV via Smart View, but the devices are persistently unable to see each other? This problem is more common than it seems — and the reasons are not only in the settings of the TV, but also in the peculiarities of wireless transmission protocols. In 2026, manufacturers continue to use different standards for Miracast and Google Cast, which creates compatibility conflicts even between modern devices.
In this article, we’ll break down the unique feature of Xiaomi’s Amlogic TVs: they often require manual activation of Wi-Fi Direct mode through the engineering menu, which is not in the documentation, and learn how to get around the limitations of Samsung’s Smart View, which by default only searches for its brand TVs, and why upgrading to MIUI TV 3.0+ fixes the problem 80 percent of the time.
Spoiler: If your Xiaomi Mi TV 4A/4S/5 TV was released before the 2021, you’ll need an alternative solution — a HDMI- adapter connection or third-party apps like ApowerMirror. But first, let’s check the basic settings that most users miss.
1. Compatibility Check: Does your Xiaomi Smart View support?
Not all Xiaomi TVs are Samsung Smart View compatible by default, as Smart View uses Samsung’s proprietary Miracast protocol, while Xiaomi’s new models favor Google Cast (Chromecast) and AirPlay (post-2022 firmware).
- 📺 Supported Xiaomi models: Mi TV Q2 2023+, Mi TV 6, Redmi Smart TV X (with firmware MIUI TV 3.0 and later). These devices have built-in Wi-Fi Direct support for Miracast.
- ❌ Problem models: Mi TV 4A/4S (2018–2020), Mi TV 5 (prior to the 2022 update) require manual compatibility mode activation.
- 🔄 Alternative protocols: If Miracast doesn't work, try Google Cast (via Google Home app) or DLNA (for transferring media files).
To determine exactly compatibility, check your TV’s firmware version:
- Open the settings → About TV → The version of the software.
- If the version is older than MIUI TV 2.5.67, the update is mandatory (instructions in section 4).
- For models up to 2021, find the Wireless Display option on the menu, which means no Miracast support.
2. Network setup: why TV is not visible on one Wi-Fi network
The most common mistake is trying to connect to a TV via Smart View when the smartphone and TV are on different subnets, and even if both devices are connected to the same router, problems can arise from:
- 🌐 Double NAT: If the router is in bridge mode or connected to another router (e.g., from a provider).
- 🔒 Client isolation (AP Isolation): enabled in router settings (often by default on TP-Link and Keenetic).
- 📶 Different Wi-Fi frequencies: the smartphone is connected to 5 GHz, and the TV is connected to 2.4 GHz (or vice versa).
How to check and correct:
| Problem. | How to check | Decision |
|---|---|---|
| Different subnets | On your smartphone and TV, check IP- address in Settings → Wi-Fi → Network details. The first 3 digits should match (e.g., 192.168.1.x). | Restart your router or assign static IPs to a single subnet. |
| AP Isolation | Go to the router’s web interface (usually 192.168.1.1) and look for the option “Client Isolation” or “Customer Isolation”. | Turn off this function and save the settings. |
| Different Wi-Fi frequencies | In the Wi-Fi settings on TV and smartphone, look at how often the devices are connected. | Connect both devices to the same frequency (recommended 5 GHz for stability). |
⚠️ Warning: If your router supports MU-MIMO or Beamforming, temporarily disable these features—they may block device discovery through Miracast.
Make sure your smartphone and TV are on the same Wi-Fi network|

Check that the "Wireless Projection" mode is on TV |

3. Enable hidden modes on Xiaomi: Wi-Fi Direct and Miracast
Xiaomi TVs often hide the Wi-Fi Direct and Miracast settings in the engineering menu, which is designed to make the interface easier, but creates problems when connecting to third-party devices.
For Mi TV 4A/4S/5 models (2018–2022):
- Open the Mi Remote app on your smartphone or use the remote.
- Go to Settings → Device → About this device.
- Click on MIUI TV Version 5 times in a row until the message “You are a developer” appears.
- Go back to the main settings menu and open a new section for developers.
- Activate options: Wi-Fi Direct (enable) Miracast (wireless display) (enable) Wi-Fi debugging (optional, for diagnosis)
For the Mi TV Q2/6 (2023+) models:
- Go to Settings → Connection and Sharing → Wireless projection.
- Select Additional Settings and activate Miracast Compatibility Mode.
- If you do not have an option, update the firmware (section 4).
What to do if there is no “Developers” item?
4. firmware update: why the old version blocks Smart View
Manufacturers regularly release updates to fix compatibility issues, such as the MIUI TV 3.0.14 firmware (released in March 2023) that added Miracast support for Samsung devices, and earlier versions of the protocol only worked with Xiaomi and Redmi phones.
How to update firmware:
- Go to Settings → About TV → System Update.
- If the update is not automatically available, download the latest version manually from the official Xiaomi Support website (select your TV model).
- Copy the firmware file (.zip format) on the USB- drive and connect it to the TV.
- In the update menu, select Local Update and specify the path to the file.
⚠️ Warning: If the TV stops turning on or freezes on the logo after the update, reset to factory settings via Restore Mode (hold Power + Menu on the remote when turned on).
List of firmware with support for Smart View:
- 📦 Mi TV 4A/4S: MIUI TV 2.5.67 and later (update from 2022 years).
- 📦 Mi TV 5: MIUI TV 3.0.14 (March 2023).
- 📦 Redmi Smart TV X: Any firmware after 1.0.102.
💡
If your TV is not updated via the Internet, use the USB- method. The firmware file should be called update.zip and lie at the root of the flash drive (not in the folder!).
5. Alternative ways to connect: if the Smart View does not work
If all of the above methods have failed, consider alternative screen transfer options:
| Method | Required. | Pluses | Cons |
|---|---|---|---|
| Google Cast (Chromecast) | Google Home app on your smartphone | Works on all Xiaomi with MIUI TV 2.0+, stable connection | 1–2 second delay, does not support games |
| HDMI- adapter (e.g. USB-C to HDMI) | Cable or adapter (~1500–3000 ₽) | Zero delay, works with any device | Wired connection, occupies HDMI- port |
| ApowerMirror or TeamViewer QuickSupport | Installation of the application on TV and smartphone | It works even on older models, management support | Registration is required, lags are possible |
| DLNA (for media files) | Built into TV, BubbleUPnP app on smartphone | No Internet connection, supports 4K | For photo/video only, no screen broadcast |
To connect via Google Cast:
- Install the Google Home app on your smartphone.
- Make sure that the TV and phone are on the same Wi-Fi network.
- In the application, click + → Set up the device → Transfer the screen.
- Choose your Xiaomi TV from the list.
💡
If you use the HDMI- adapter, select USB- debugging (for Android) or Duplicate screen (for iPhone) in your smartphone settings, which will reduce the latency to 50 ms.
Diagnostics of malfunctions: when the problem is in the "iron"
If none of the software methods worked, the problem could be in the hardware, and here are the typical irony reasons:
- 📡 Faulty Wi-Fi module: Xiaomi TVs often fail the 2.4 GHz antenna (check if the TV is connected to the Internet).
- 🔌 Power problems: If the TV doesn't get enough power, the Wi-Fi Direct module can shut down. Try another power cable.
- 🛠️ Damaged connector HDMI: If adapters were previously connected, the contacts could oxidize (purging alcohol helps in 60% of cases).
How to check for hardware faults:
- Wi-Fi test: Connect the TV to another network (e.g., from a phone in hotspot mode) if the connection is unstable, the module is a problem.
- Port Check: Connect another HDMI device to your TV (e.g., a set-top box) and if the image flashes, the port is faulty.
- Diagnostics of power: Listen to TV – if you hear a high-frequency squeak, it is a sign of unstable tension (a replacement of the power supply is required).
⚠️ Warning: The Xiaomi Mi TV 4A (2018) TVs often overheat the Amlogic S905 chip, resulting in Wi-Fi shutdown. The solution is to provide ventilation (don't put the TV in a closed cabinet) or replace the thermal paste.
7. Frequent mistakes and how to avoid them
Many users make the same mistakes when setting up Smart View. Here are the top -5 misses and how to fix them:
- 🔄 "Rebooted router, but didn't help": You actually need to reboot the router, the TV, and the smartphone at the same time. Sequence: turn off the TV → restart the router → turn on the TV → start Smart View on the phone.
- 📵 "Enabled Wi-Fi Direct, but no TV visible": Make sure your smartphone has modem turned off (it blocks Miracast). Also check that the TV has Wireless projection settings on All devices, not just known ones.
- 🔒 Forgot to reset network settings: If you previously connected to other devices via Miracast, clear the list of associated devices: Settings → Bluetooth and devices → Forget all devices.
- 📱 "Using Old Smart View": Update the Smart View app to the latest version in the Galaxy Store (not Google Play!).Older versions don't support Xiaomi TVs.
- 🌍 "I don't take into account regional settings": Xiaomi TVs for China (CN- version) have Miracast support disabled. Check the region in Settings → Language and Region (should be Russia or Global).
💡
If your Samsung smartphone is running Android 13+, turn on the option to turn off Miracast restrictions in the developer settings (path: Settings → About Phone → Assembly Number (7 taps) → For developers).
