How to connect Xiaomi to a Samsung TV: everything from Miracast to HDMI

Connecting Xiaomi’s smartphone (or Redmi/POCO devices) to a Samsung TV offers many opportunities, from streaming movies to the big screen to showing photos or even games from the mobile. However, users often face compatibility problems — especially when it comes to combining devices from different brands. In this article, we will discuss all the current ways of connecting, including wireless protocols (Miracast, Google Cast), wired methods (HDMI via adapters), and even alternative solutions for older TV models.

It’s important to consider that Samsung and Xiaomi use different ecosystems, one focused on SmartThings and Samsung DeX, and the other on MIUI Cast and Miracast. This means there is no one-size-fits-all solution, and the choice of method depends on the TV model, the MIUI version on the smartphone, and even the year of release of the equipment. We tested all methods on current firmware (2023-2026) and collected unique recommendations for cases when standard instructions do not work.

1. Wireless connection via Miracast (Screen Mirroring)

Miracast is a wireless screen standard supported by most modern Samsung TVs (since 2015’s J series) and all Xiaomi smartphones based on MIUI 10+. The main advantage is that there is no need for a router: devices connect directly over Wi-Fi Direct.

To activate Screen Mirroring on Samsung, follow the following steps:

• 📺 On the TV remote, click Source (or Input), then select Screen Mirroring (may be called Screen Mirroring or Smart View).
• 📱 On the Xiaomi smartphone, open Settings → Connection and sharing → Screen transmission (or MIUI Cast in the notification curtain).
• 🔍 In the list of available devices, select the name of your Samsung TV (for example, the name of your Samsung TV, UE55TU8000).
• ✅ Confirm the connection on both devices.

If the TV is not on the list, check:

• 🔄 Is the TV firmware updated (in the Settings menu) → Support → Update of the PO).
• 📶 Wi-Fi on your smartphone (even if the connection is without a router).
• 🔒 Turn it off. VPN Xiaomi’s power saving mode – they can block data transfers.

2. Connect via Google Cast (Chromecast built-in)

Many Samsung TVs (starting in 2019) support Google Cast, a technology similar to Chromecast but built into firmware, which allows you to stream content from apps (YouTube, Netflix, Google Photos) directly to the TV screen without duplicating the entire interface of the smartphone.

Instructions for connection:

2. On TV, open an app that supports Cast (like YouTube).
3. Slip on the broadcast icon (📡) and choose your Samsung TV.
4. On the Xiaomi smartphone in the same app, click on the Cast icon and confirm the connection.

List of apps that support Google Cast on Samsung TV:

• 🎬 YouTube, Netflix, Disney+
• 📷 Google Photos, Galery Go

5. Alternative methods: DLNA and third-party applications

If standard methods don’t work (e.g. on older Samsung E or F series TVs), you can use DLNA or third-party mirroring apps.
