How to stream a screen from Xiaomi to a TV: all the ways from Miracast to HDMI

Broadcasting a screen from a Xiaomi smartphone to a large TV screen is not a luxury, but a necessity for comfortable watching movies, streams or presentations. However, many users face problems: connection breaks, sound disappears, picture “brakes”, the reason most often lies in the wrong method of broadcasting or incompatibility of protocols.

In this article, we will analyze all the current ways to transfer images from Redmi, POCO or flagship Xiaomi on Samsung TVs, LG, Sony and others – from wireless technologies (Miracast, Google Cast) to wired solutions (HDMI, USB-C). And we will also reveal the hidden settings. MIUI, This will help to stabilize the connection even on weak routers.

If you've tried to broadcast before and you've failed, don't be quick to blame your smartphone. 80 percent of the time, the solution is to change protocol or update your TV firmware, and let's start with the simplest and most reliable method.

1. Wireless broadcast on Miracast (without router)

Miracast is a wireless screen standard built into most modern Xiaomi smartphones and TVs (since 2013), with the main advantage of not needing an internet or router – the connection is established directly between devices.

To begin the broadcast:

1. On your TV, activate Screen Mirroring (Samsung: Smart View; LG: Miracast) usually via Settings → Network → Screen Mirroring.
2. On a Xiaomi smartphone, open Settings → Connection and Sharing → Screen Transfer.
3. In the list of available devices, select the name of your TV. Confirm the connection on both devices.

If the TV is not on the list, check:

• 🔄 Is the firmware on TV updated (especially relevant for models older than 2018).
• 📶 Wi-Fi on your smartphone (even if you don’t have a network connection).
• 🔒 Is it off? VPN Firewalls that block local connections.

⚠️ Note: On some Xiaomi models (e.g. Redmi Note 8 Pro), the Miracast feature may be hidden. → About the phone and 5 times tap on the version MIUI. After that, the menu will appear item For developers, where you need to turn on the Wireless display.

2. Google Cast (Chromecast) – broadcast via router

Google Cast (or Chromecast) is a technology from Google that allows you to stream DLNA-enabled content to Android TVs or Chromecast devices. Unlike Miracast, you need a router here, as both devices must be on the same network.

Instructions for connection:

1. Make sure your smartphone and TV are connected to the same Wi-Fi network.
2. On your TV, open the Google Home app (if not, install it from the Play Market).
3. In the Google Home app on your smartphone, tap the Screen Transfer (or Cast) icon and select your TV.

If the broadcast is interrupted or slows down:

• 📡 Reconnect both devices to a 5GHz network (if the router is dual-band).
• 🔧 In router settings, disable Band Steering (automatic switching between 2.4 and 5 GHz).
• 🔄 Restart the router and update the TV firmware.

Are the devices connected to a single Wi-Fi network?

Are Google Home and MIUI apps updated?

Is the developer mode on the TV (for Android TV) enabled?

Are the energy-saving modes on the smartphone turned off?

Important: On Samsung TVs with Tizen (models up to 2020), the Google Cast may not work due to manufacturer restrictions. HDMI-adapter.

3. Wired connection via HDMI or USB-C

If wireless methods are unstable, wired HDMI or USB-C connectivity is the best solution, and this will require an adapter (such as USB-C to HDMI) that supports video output.

Step-by-step:

1. Connect the adapter to the USB-C port on your smartphone.
2. Connect the adapter to the TV through HDMI-cable.
3. On the TV, select the appropriate HDMI-signal-input.
4. On the smartphone in the notification bar will appear the option Transfer over HDMI – activate it.

Advantages of wired connection:

• ⚡ Zero Latency – Ideal for High-Resolution Games or Videos.
• 🎮 Support 4K@60Hz (If the adapter and TV are supported).
• 🔋 Charging the smartphone during broadcast (if the adapter with a port) USB-PD).

⚠️ Note: Xiaomi smartphones with a MediaTek processor (for example, Redmi Note 10) may not work audio output through the mediaTek processor HDMI. In this case, use a separate Bluetooth speaker or 3.5 mm audio jack.

4. Broadcasting through apps (YouTube, Netflix, Twitch)

Many streaming services (YouTube, Netflix, Twitch) support live streaming to the TV without mirroring the entire screen, saving battery life and reducing latency.

How it works:

1. Open an app (like YouTube) on your smartphone.
2. Slip on the Cast icon (usually in the upper right corner).
3. Choose your TV from the list.
4. The video will start playing on TV, and the smartphone can be used as a remote.

List of applications with Cast support:

• 🎬 YouTube (including Premium)
• 🎥 Netflix (subscription required)
• 🎮 Twitch and Trovo
• 📺 Disney+, HBO Max, Okko
• 🎵 Spotify (audio only)

💡

If the Cast icon doesn’t appear, upgrade to the latest version or reinstall it. On some MIUI firmware (e.g. MIUI 13 for India region), Cast may be disabled – check your region settings in Settings → Additional → Region

5. Hidden MIUI settings for stable broadcast

If the broadcast is permanently cut off or the image is "freezite", the problem may lie in the hidden limitations of MIUI.

Disconnecting energy saving for Wi-Fi:

1. Go to Settings → Battery and Performance → Battery Consumption Management.
2. Find the Wi-Fi app (or Screen Mirroring) and select Unlimited.

Change in firmware region:

On some firmware (e.g. MIUI Global for Redmi Note 9), Miracast is not stable.

1. Install firmware for the EEA region (Europe) via Fastboot.
2. Or change the region manually through ADB: adb shell settings put global device_provisioned 1 adb shell settings put secure user_setup_complete 1 adb shell am start -n com.android.settings/.Settings

Setting up MTU for Wi-Fi:

If the broadcast is slowing down on IPv6 routers, try reducing the MTU:

1. Connect to the router via your browser (usually 192.168.1.1).
2. In Wi-Fi settings, find the MTU setting and set the value 1400.
3. Reboot the router.

6. Alternative methods: DLNA, AirPlay and third-party applications

If standard methods do not work, alternative protocols or third-party applications can be used.

DLNA (for media files):

DLNA technology allows you to broadcast only media files (video, photos, music), but not the entire screen.

1. Turn it on on the TV. DLNA-server (usually in the Network section).
2. On your smartphone, install the BubbleUPnP or LocalCast app.
3. Select a file to broadcast and specify the TV as the output device.

If you have an Apple TV or an AirPlay 2-enabled TV (like the LG OLED 2021+), you can stream the screen via:

1. Install the AirScreen or ApowerMirror app on your smartphone.
2. Connect both devices to the same Wi-Fi network.
3. In the app, select the TV and activate mirroring.

Side of the mirroring annex:

• 🖥️ ApowerMirror – supports screen recording and control with TV.
• 🎮 TeamViewer QuickSupport - for remote access (suitable for presentations).
• 📱 Screen Mirroring (by Google) – a simplified version for older devices.

💡

For broadcasting games (for example, Genshin Impact or Call of Duty Mobile), it is better to use a wired connection via HDMI - delays are minimal (less than 20 ms), whereas on Wi-Fi they can reach 100+ ms.

7. Problem Solving: Why is the broadcast not working?

If none of the methods worked, check the following points:

Problem 1: The TV is not displayed in the list of devices

• 🔌 Make sure your TV is on Screen Mirroring.
• 🔄 Reboot both devices.
• 📱 Turn off Flight Mode and turn on Wi-Fi (even for Miracast).

Problem 2: The broadcast is interrupted or slowed down
