Synchronizing Xiaomi’s smartphone with a Samsung TV opens up new possibilities for viewing content, gaming, and managing devices. However, due to ecosystem differences (MIUI vs Tizen OS), users often face compatibility issues, image delays, or sudden communication breaks. In this article, we will break down all the current ways of connecting, from wireless protocols to wired solutions, and provide specific recommendations for eliminating typical bugs.
It is important to understand that the choice of method depends on your tasks:
- 🎮 For games, it is better to use them. HDMI (Minimum latency or Miracast (if the TV supports Game Mode).
- 🎬 For video, it's optimal. DLNA Smart View (no reference to phone screen resolution).
- 🔧 For TV management, Samsung SmartThings app is suitable (if the phone supports TV). IR-blaster or Wi-Fi Direct).
Before you start, check:
- 📱 Xiaomi phone has Wi-Fi and Bluetooth enabled (for some methods).
- 📺 Samsung TV is connected to the same network (for example, the same TV) DLNA/Smart View).
- 🔄 Both devices are updated to the latest software versions (especially relevant for models older than 2020).
1. Connection via Miracast (wireless screen duplication)
Miracast is the wireless image standard that most modern Xiaomi devices (starting with the Redmi Note 5) and Samsung TVs (QLED, CU, AU and later) support, with the main advantage of being unbound to the Internet: the connection is established directly between the phone and TV.
How to turn Miracast on Xiaomi:
- Open Settings → Connection and Sharing → Wireless display.
- Activate the Wireless display slider.
- In the list of available devices, select your Samsung TV (model name will be displayed automatically).
On Samsung TV:
- Press Source (or Input) on the remote.
- Select Screen Mirroring (Smart View in some models).
- Confirm the connection on the phone when the request appears.
⚠️ Note: If the phone screen is not displayed on TV, check it out: 🔌 Both devices must be within a 5-meter radius (walls and interference reduce signal). 📶 On Samsung TV, turn off the power saving mode (Settings) → General. → Eco-mode, as it can block Miracast.

| Parameter | Miracast | Smart View |
|---|---|---|
| Demands the Internet. | ❌ No. | ✅ Yes (or Wi-Fi Direct) |
| Max, permission. | 1080p (on most models) | 4K (depends on TV) |
