Why is Samsung’s wireless connection to Xiaomi TV causing problems?
Wirelessly streaming a smartphone screen to a TV should be a simple procedure, but in practice, users of Samsung Galaxy and Xiaomi TV face a lot of nuances. The main reason is different wireless transmission protocols: Samsung traditionally uses Smart View (based on Miracast), and Xiaomi in new models prefers its own Mi Screen Sharing or Wi-Fi Direct, which leads to compatibility conflicts, especially if the TV or phone is released before 2020.
The second common problem is the unstable connection due to congested Wi-Fi network. Many users try to stream video in 4K resolution through a home router, not realizing that it requires a 5 GHz channel with a bandwidth of at least 300 Mbps. As a result, sound stuttering, image artifacts and sudden communication breaks. This article will help avoid typical errors and choose the best way to connect depending on your devices.
Method 1: Connect via Wi-Fi Direct (most universal)
Wi-Fi Direct works on all Xiaomi TV models (including Mi TV 4A/4S/5X) and most Samsung smartphones (starting with the Galaxy S8). Its main advantage is a direct connection without a router, which eliminates delays due to congested network. However, the method has a limitation: the maximum broadcast resolution is 1080p at 30 frames / s.
To activate Wi-Fi Direct on your Xiaomi TV:
- Open the settings (cog on the remote).
- Go to the Web and the Internet → Wi-Fi Direct.
- Turn on the feature and wait until the TV is visible to other devices.
On a Samsung smartphone:
- 📱 Open the Settings. → Connections → Wi-Fi Direct.
- 🔍 In the list of available devices, select your Xiaomi TV (The name will include a model, for example. MiTV-5X-1234).
- 🔑 Confirm the connection on both devices (entry may be required) PIN-TV-screen code).

An important nuance: if the image is not automatically broadcasted after the connection, the TV may need to manually select the source of the signal. To do this, click the Input button (or Source) on the remote and select Wi-Fi Direct or Screen Mirroring.
Method 2: Using Miracast (for Samsung models with support)
Miracast is a wireless broadcast standard that most modern Samsung Galaxy (starting with the Galaxy S6) and Xiaomi TVs on Android TVs support. Unlike Wi-Fi Direct, this method allows you to broadcast the screen in resolution up to 4K, but requires a more stable connection.
Instructions for Xiaomi TV:

What if Miracast can't find the TV?
⚠️ Note: If you have Xiaomi TV Stick or Mi Box, Screen Mirroring may not work properly due to the limitations of iron, in which case it is better to use Google Cast (if supported).
Method 3: Broadcast via Google Cast (for Chromecast models)
Some Xiaomi TVs (such as the Mi TV Q1/Q2 or Google TV models) support the Google Cast protocol, which allows you to stream content from individual applications (YouTube, Netflix, browser) without full screen duplication, a method less resource-intensive than Miracast, and provides smoother playback.
