How to Connect Xiaomi 8 Pro to a TV via Wi-Fi: A Complete Guide to Error Solutions

Why Wi-Fi is better than cable for Xiaomi 8 Pro

Wireless screen broadcast from the smartphone Xiaomi 8 Pro to the TV via Wi-Fi solves two key problems: eliminates confusion wires and preserves the mobility of the device. HDMI-cable USB-C → HDMI-With adapters that limit the range to 1-2 meters, Wi-Fi allows you to manage content from the sofa without getting up, especially for owners of the Xiaomi 8 Pro with its 6.28" AMOLED-Screen – broadcasting movies, games or presentations to the big screen does not require physical connection.

Another advantage is versatility: Modern TVs (since 2016) support at least 2-3 wireless protocols: Miracast, DLNA or Google Cast. And the Xiaomi 8 Pro based on MIUI 10+ can work with all of them. This means that you don’t have to buy additional devices like Chromecast or Mi TV Stick — you can set up your existing equipment correctly enough, but there is a major difficulty: the choice of the optimal connection method depends on the TV model, the version of the smartphone’s firmware, and even the router.

In this article, we will discuss 5 working ways to connect Xiaomi 8 Pro to TV over Wi-Fi, including hidden MIUI features, bypassing typical errors (for example, “I failed to connect to the display”) and optimizing broadcast quality for games and video in 4K. Particular attention will be paid to compatibility with Samsung, LG and Xiaomi Mi TVs, where the connection algorithms are fundamentally different.

Method 1: Miracast – Direct connection without router

Miracast is a wireless screen standard built into the Xiaomi 8 Pro at Android 8.1 Oreo. Its key advantage is that it works without a router intermediary: a smartphone and a TV connect directly to a point-to-point principle, ideal for a summer cottage, hotel or office where there is no access to the local network.

To activate Miracast on Xiaomi 8 Pro:

1. Open Settings → Connections and Sharing → Wireless display.
2. Turn on the Wireless Display slider (in some versions of MIUI, the item is called "Transmit to TV").
3. Wait for the smartphone to find the available devices. The TV must be Miracast standby (usually activated via Signal Source). → Screen Mirroring).
4. Select your TV name from the list. Confirm the connection on both devices.

Important: Miracast on Xiaomi 8 Pro supports maximum resolution 1920×1080 upon 30 Hz. 4K-content or games with high FPS This method is not suitable - there will be a noticeable delay of the picture (lag to the 100–150 It's guaranteed to work even without the Internet.

Method 2: Google Cast (Chromecast) – for streaming music and video

If your TV is equipped with a built-in Google Cast (such as Sony Bravia models with Android TV or Xiaomi Mi TV 4S) or connected to a device like Chromecast, use this method. Unlike Miracast, Google Cast does not duplicate the screen of your smartphone, but only transfers content (video, music, photos) from supported applications (YouTube, Netflix, Google Photos).

Instructions for Xiaomi 8 Pro:

• 📱 Make sure your smartphone and TV are connected to the same Wi-Fi network.
• 🎬 Open an app with supported content (e.g. YouTube).
• 🔍 Click on the broadcast icon (usually in the top right corner) and select your TV from the list.
• 📺 On the TV screen will appear a notification of the beginning of playback.

The advantages of Google Cast:

• 🎥 Support 4K HDR Dolby Atmos (if the TV is compatible).
• 🔋 Minimum battery load Xiaomi 8 Pro – content streamed directly from the Internet, not from the smartphone.
• 🎮 The ability to continue using your phone while broadcasting (e.g., reading comments on a video).

⚠️ Attention: Xiaomi 8 Pro with MIUI 12+ You may experience a “Device Unconnected” error when using Google Cast. Solution: Turn off Network Optimization in Settings → Special facilities → For developers.

Method 3: DLNA – for local files (photos, videos, music)

DLNA (Digital Living Network Alliance) is a protocol for sharing media over a local network, unlike Miracast and Google Cast, it doesn't broadcast a screen, but provides access to files on a smartphone, which is convenient for watching home videos, photos or listening to music without downloading to the TV.

How to set up DLNA on Xiaomi 8 Pro:

1. Install a server application, such as BubbleUPnP or LocalCast (available on Google Play).
2. Turn on Wi-Fi on your smartphone and connect to the same network as the TV.
3. Launch the application and activate it "DLNA-server (in BubbleUPnP this is the "Renderers" item").
4. On your TV, open a media player (like LG’s Photos and Videos or Samsung’s Media) and select the Xiaomi 8 Pro as the source.

DLNA limitations:

• 🚫 No screen broadcasts, only individual files.
• 📁 Not all video formats are supported (e.g..mkv with.mkv). AC3-sound may not be reproduced).
• 🔄 With a large amount of files, slowdowns are possible.

💡

If the TV doesn’t see the Xiaomi 8 Pro on DLNA, check if the router’s firewall is blocking access. Try temporarily disabling AP Isolation in the router settings.

Method 4: Hidden MIUI function – “Screen projection” (for Xiaomi TVs)

Owners of Xiaomi Mi TVs (series 4A, 4S, 5) can use the proprietary projection protocol, which is more stable than Miracast and supports 1080p@60fps. This feature is hidden in the depths of MIUI and requires activation through the "Developer Settings".

Step-by-step:

1. Activate Developer Mode on Xiaomi 8 Pro: go to Settings → About Phone and 7 times click on MIUI Version.
2. Return to Settings → Additional → For developers and turn on “Debugging over Wi-Fi”.
3. On Xiaomi TV, open Settings → Connection and Sharing → Screen Projection.
4. On your smartphone, in the same Wi-Fi network, launch the “Mi Remote” application (pre-installed in MIUI) and select “Projection on TV”.

Advantages of this method:

• 🔄 Minimum latency (30–50 ms), which is critical for gaming.
• 🎛 Support HDR10 and extended color scheme DC-P3.
• 🔒 Automatic traffic encryption (unlike Miracast).

Method 5: Third-party applications (ApowerMirror, TeamViewer)

If built-in methods don't work (e.g., because of outdated TV firmware), use third-party apps that support additional protocols and often solve compatibility problems.

1. ApowerMirror (for screen duplication):

• 📱 Install ApowerMirror on Xiaomi 8 Pro and PC/TV with Android TV.
• 🔗 Connect both devices to the same Wi-Fi network.
• 🖥 On the TV, launch the application and select "Receiving device".
• 📲 On your smartphone, click "Mirror" and select the TV from the list.

2. TeamViewer QuickSupport (for remote control):

• 🔑 Suitable if you need not just broadcast the screen, but to control the smartphone from the TV (for example, for presentations).
• 📶 Requires stable Wi-Fi (5GHz recommended).
• 🔒 All data is transmitted in encrypted form.

Cons of third-party applications:

• 💰 Some features are paid (for example, ApowerMirror limits the free version to resolution). 720p).
• 🛠 Require more resources than built-in protocols (can warm up the Snapdragon 710 processor in the Xiaomi 8 Pro).

💡

The app side is the only way to connect the Xiaomi 8 Pro to TVs older than 2015 that don’t support Miracast or DLNA.

Typical errors and their solutions

Even if you set up your Wi-Fi connection correctly, you can interrupt it, and let's look at the 5 most common problems and how to fix them:

If none of the methods worked, check:

• 📶 Wi-Fi signal: for stable broadcasting, you need a level not lower -60 dBm (tested in Wi-Fi Analyzer).
• 🔋 Battery charge: below 20% Xiaomi 8 Pro automatically limits performance.
• 🔄 Firmware region: on Chinese versions MIUI Miracast support may be disabled.
