How to connect Xiaomi smartphone to Samsung TV: all ways with photos and videos

Connecting Xiaomi to a Samsung TV opens up a lot of possibilities, from watching photos on a large screen to streaming 4K videos without losing quality. However, many users face compatibility problems — especially when it comes to connecting devices of different brands. In this article, we will discuss all the current ways of connecting (including hidden features of MIUI and Tizen OS), point out common errors and give recommendations for optimizing picture and sound.

It’s important to understand that the way you connect depends on your TV model (QLED, Crystal UHD, The Frame, etc.), the version of MIUI on your smartphone, and even the router’s firmware if you use wireless technology. For example, the Xiaomi 13 Pro with MIUI 15 supports Wi-Fi 6E, which speeds up Miracast broadcasts by 30% compared to older models. And Samsung 2023 TVs (such as the QN90C) have built-in AirPlay 2, which makes it easier to connect via Apple TV... but what about Xiaomi owners?

We tested everything from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra, and Samsung’s Q60B, CU8000 and LS03B (The Frame) series, and found 5 working methods, including one little-known trick using Samsung’s DeX to control the phone from the remote. Ready? Let’s start with the simplest version.

1. Wi-Fi Direct (Screen Mirroring)

This is the most versatile way, which works on all Xiaomi models (starting with MIUI 9) and Samsung TVs with Tizen OS (2016 and later), the main advantage is that you do not need a router: devices connect directly via the Miracast protocol.

To activate Screen Mirroring:

• 📱 On your smartphone: open Settings → Connections and sharing → Screen transfer (or Cast in the notification curtain) Select your TV from the list.
• 📺 On TV: Go to Settings → General. → External devices → Screen mirroring device (on new models, the path may differ: Source → Screen Mirroring).
• 🔄 If the connection doesn't get established, try restarting both devices and trying again. MIUI help VPN.

The speed of data transfer over Wi-Fi Direct depends on the version of the protocol:

• 📶 Wi-Fi 4 (802.11n): up to 300 Mbps – suitable for Full HD, But it's possible to play lags.
• 📶 Wi-Fi 5 (802.11ac): before 866 Mbit/s – works consistently with 4K@30fps.
• 📶 Wi-Fi 6/6E: before 2400 Mbit/s - supports 4K@60fps and HDR10+.

⚠️ Note: Samsung TVs of the J series (2015-2017 d.) Screen Mirroring may not be available. HDMI-Adapter or Google Cast (if the TV supports YouTube or Netflix).

2. Connection through HDMI (adapter-wise USB-C/HDMI)

If you want the best picture quality (for example, to watch movies in 4K HDR or games), HDMI is the best choice. For modern Xiaomi smartphones (with a USB-C port), you will need a USB-C → HDMI adapter. Importantly, not all adapters support 4K@60Hz - check the specifications before buying.

Step-by-step:

1. Buy a certified adapter (we recommend the Anker 810 or the original from Xiaomi).
2. Connect the adapter to the smartphone, and HDMI-cable to the TV (to the port) HDMI 2.1. 4K).
3. On the TV, select the appropriate signal source (Source → HDMI).
4. On the smartphone, a request for display mode may appear - select "External screen" or "Duplicate".

⚠️ Note: Some Samsung TVs (e.g. series) AU7000) when connected through HDMI Solution: In your smartphone settings, go to Sound. → Sound output → HDMI and select "Auto".
