How to connect Xiaomi phone to Samsung Smart TV: the complete guide

Connecting Xiaomi’s smartphone to a Samsung Smart TV offers a range of possibilities, from viewing photos on a large screen to streaming high-resolution videos. However, not everyone knows that there are 5 different ways to sync these devices, from wireless technologies to wired connections. Each method has its own nuances, depending on the phone model (for example, Redmi Note 12 or Xiaomi 13 Ultra) and the TV firmware version (Tizen 5.5 vs 7.0).

In this article, we will discuss all the current ways of connecting, including screen-miraring via Miracast, using a HDMI- adapter (Type-C/USB-C), as well as alternative solutions through Google Cast and SmartThings. Particular attention will be paid to typical errors, such as the lack of image when connecting via cable or delays during wireless broadcasting. If you have previously encountered synchronization problems, here you will find proven solutions.

1. Preparation of devices before connection

Before you start syncing, make sure both devices meet the minimum requirements. Samsung Smart TVs are critical to have the latest version of Tizen firmware (check in Settings → Support → Software Update). Outdated models (such as the J or K series 2016–2017) may not support modern wireless transmission protocols.

From Xiaomi's side, check out:

• 📱 Version MIUI: Up-to-date builds (14+) work better with Miracast and Google Cast. Outdated versions (MIUI 12 and below) may require manual tuning.
• 🔄 Developer Mode: If you plan to use ADB to debug the connection (relevant to POCO F5 and other custom firmware models).
• 🔋 Battery charge: Wireless transmissions increase energy consumption by 30 to 40 percent, recommended levels at least 50 percent.

⚠️ Note: If your Samsung is yours TV It belongs to the Crystal series. UHD 2020–2021 (models) TU7000, TU8000), In the network settings, you can turn off the Wi-Fi Direct protocol. Turn it on manually through Settings. → General. → External devices → Connection devices → Wi-Fi Direct.

If you’re connecting a Xiaomi Pad 6 or other tablet, note that some Samsung TVs may not recognize them as the signal source, in which case it will help to force the “Developers” mode → “Debugging over USB” (even if the connection is over Wi-Fi).

2. Wireless connection via Miracast (Screen Mirroring)

Miracast is a wireless screen transfer standard built into most modern Xiaomi and Samsung devices.It allows you to duplicate your phone screen onto your TV without additional cables, but requires both devices to be connected to the same Wi-Fi network (or use Wi-Fi Direct).

Instructions for Xiaomi (on the example of Redmi Note 11 Pro+):

1. Open Settings → Connections and Sharing → Screen Transfer.
2. Select Wireless Display (or Miracast in older versions of MIUI).
3. In the list of available devices, find your Samsung TV (the name will match the model, for example, UE55CU8000).
4. Confirm the connection on the TV (entry may be required) PIN-code).

From the Samsung TV side:

1. Press the Source button on the remote.
2. Select Screen Mirroring (or Smart View in older models).
3. Wait for your Xiaomi phone name to appear on the list and confirm the connection.

Both devices are connected to the same Wi-Fi network (5GHz is preferred)|

The distance between the devices does not exceed 5 meters-->

⚠️ Note: On Samsung TV series QLED 2022–2023 (models) QN90B, QN85C) If the screen isn't showing up, try it: 🔄 Reboot both devices. 📶 Connect to your TV via Wi-Fi Direct (instead of a shared network). 🔧 In settings of TV, disable Smart Security Mode (Settings) → General. → Smart functions).

If the image is transmitted with a delay (lag), try:

• 🎮 Reduce the screen resolution of the phone to 1280×720 (in the developer settings).
• 📶 Switch to a 5 GHz network (if 2.4 GHz was used).
• 🔌 Connect your phone to charge – performance limitations due to low battery power can affect ping.

💡

Miracast is the most versatile way, but it's sensitive to interference on the web. For games and videos, it's better to use HDMI or Google Cast.

3 Connection via HDMI (with Type-C/USB-C adapter)

Wired HDMI connectivity guarantees minimal latency and maximum image quality (up to 4K@60Hz on supported models).However, this will require a USB-C adapter (or Micro-USB for older Xiaomi) on HDMI.

• 🔌 Original Xiaomi USB-C to HDMI (supports 4K@30Hz).
• 🔌 Baseus USB-C Hub (with HDMI + USB + SD-card ports).
• 🔌 UGREEN 4K@60Hz (for the Xiaomi 13/14 series).

Step-by-step:

1. Connect the adapter to the Xiaomi phone.
2. Connect the adapter to the TV through HDMI-cable (use the port) HDMI 1/ARC for better compatibility).
3. On the TV, select the source of the signal: Source → HDMI (specify the appropriate port).
4. The phone may have a request to select a transfer mode – select Screen Transfer or DeX (if supported).

Important: On Xiaomi phones with a Snapdragon 8 Gen 2 processor (such as Xiaomi 13 Pro) when connecting via HDMI, you may need to turn on the “Developers for” mode and activate the “Debugging by HDMI” option (Settings → About Phone → MIUI version – 7 times press to unlock the developer menu).

💡

If the adapter is not detected, try connecting it via an externally powered USB-Hab – some Xiaomi models (e.g., POCO X5 Pro) require additional power supply to run the HDMI- Output.

4.Use of Google Cast (Chromecast built-in)

Samsung’s 2020 and newer TVs (starting with the TU8000) support Google Cast, a technology similar to the Chromecast but without having to buy a separate device, allowing content from supported apps (YouTube, Netflix, Mi Video) to be streamed directly to the TV without duplicating the entire screen of the phone.

How to set up:

1. Make sure your phone and TV are connected to the same Wi-Fi network.
2. On your TV, turn on Google Cast: Settings → General → External Devices → Connection Devices → Google Cast.
3. Open a supported app on your phone (like YouTube).
4. Slip the broadcast icon (📺) and select your Samsung TV from the list.

List of apps that support Google Cast:

• 🎬 YouTube, Netflix, Disney+
• 🎵 Spotify, Yandex Music
• 📱 Mi Video, MX Player (with DLNA support)

⚠️ Warning: Xiaomi phones with HyperOS shells (such as Xiaomi 14) may not have built-in support for Google Cast in system applications. In this case, use third-party utilities such as LocalCast or BubbleUPnP.

If the TV is not displayed in the list of broadcast devices:

• 🔄 Reboot the router.
