How to turn Miracast on your Xiaomi TV: a complete guide to setting up and fixing bugs

Wirelessly streaming a screen from your phone, laptop or tablet to a large screen on Xiaomi TV via Miracast is a convenient way to show presentations, watch movies or games without unnecessary wires. However, many users face difficulties when connecting for the first time: the feature can be hidden in the depths of the menu, and on some models of Mi TV or Redmi Smart TV, its activation requires additional manipulation.

In this article, we will not only show where the Miracast Display option is located in the firmware of your TV, but also analyze the nuances of compatibility with different source devices (Android, Windows, iOS), and also give recommendations for eliminating typical errors - from the lack of a signal to problems with the Internet. We will pay special attention to the Xiaomi TV A2, P1, Q2 and Redmi Smart TV X models, where the settings may differ.

If you’ve tried Wi-Fi Direct or DLNA before, but you’ve experienced delays or poor picture quality, Miracast is the best solution – it transmits images with minimal latency (up to 30 ms) and supports resolution up to 4K@60Hz on compatible models.

What is Miracast and why it is better than other wireless technologies

Miracast (or Wi-Fi Display) is a standard for wirelessly transferring video and sound from one device to another without intermediaries like a router. Unlike Chromecast or AirPlay, it does not require an Internet connection: the TV and the source (smartphone, PC) create a direct peer-to-peer connection over Wi-Fi Direct.

The advantages of Miracast on Xiaomi TVs:

• 🔹 Minimum latency is ideal for gaming and video chats (unlike DLNA, where lag can reach 2-3 seconds).
• 📺 High resolution support up to 3840×2160 (4K) on models with HDMI2.1 (e.g., Mi TV Q2 75).
• 🔌 No router dependency – works even in places without internet (unlike Google Cast).
• 📱 Universal Compatibility – Supported on Android (starting with version 4.2), Windows (8.1+) and some iOS devices (with limitations).

However, there are drawbacks: Miracast is sensitive to interference in the air (especially at 2.4 GHz), and older Xiaomi TV models (for example, Mi TV 4A 2018) may not support 5 GHz, which affects the stability of the connection. Some apps (such as Netflix or Disney+) block Miracast broadcasts because of DRM- protection.

Does your Xiaomi TV support Miracast technology: model check

Not all Xiaomi TVs are equipped with Miracast hardware. To avoid disappointment, check your model in the table below. Note that even if your Mi TV is on the list, the feature can be disabled in the firmware - we will discuss this in the next section.

If your model is not in the table, check for the feature along the way: Settings → Connections → Wireless display. If there is no point, then hardware support is missing. The alternative is to use an external Miracast adapter (for example, Xiaomi Mi TV Stick), but this will require a free HDMI port.

⚠️ Warning: On Xiaomi TVs with firmware older than MIUI TV 2.5 (released before 2020), the Miracast feature may be hidden, in which case a software update or factory reset will help (see the "Problem Solving" section).

Step-by-step: how to turn Miracast on your Xiaomi TV

Miracast activation depends on the firmware version and the TV model, and here is a generic algorithm that will work for most Mi TVs and Redmi Smart TVs in recent years, so if you don't work at some point, go to the Problem Solving section.

Step 1: Preparing the TV

1. Turn on the TV and go to the main menu by pressing the Home button on the remote.
2. Open the settings (cog icon in the upper right corner).
3. Select Connections (or Network and Connections on older models).

Step 2: Activation of the wireless display

• 🔍 Find Wireless Display, Miracast or Screen Mirroring (name depends on firmware).
• 🔄 If there is no option, update the firmware (see the "Miracast Support Software Update" section).
• 🔘 Activate the Slider On next to the option, and the TV will start searching for available devices.

Step 3: Connecting the source device

Now set up the device from which you will broadcast the screen:

Once you've successfully connected, the screen will show up on the TV, and if the picture doesn't appear or the broadcast is interrupted, move on to the next section.

Update to support Miracast on older Xiaomi TV models

If your Xiaomi TV is released before 2020 (e.g. Mi TV 4A 32" or Mi TV 4S 55"), Miracast may not be on the menu due to outdated firmware.

Method 1: Update via the Internet

1. Go to Settings → About TV → System Update.
2. Click Check for updates.
3. If a new version is available (e.g. MIUI TV 3.0+), confirm installation.

Method 2: Update via USB (if the internet connection is unstable)

• 🔗 Download the latest firmware for your model from the official Xiaomi Support website (select a file with the.zip extension).
• 📁 Unpack the archive and copy the file update.zip flash drive (format) FAT32).
• 🔌 Connect the flash drive to the TV, then go to Settings → About TV → Update via USB.

⚠️ Warning: On Mi TV 4A (2018) models, after upgrading to MIUI TV 2.5+, the Miracast feature may appear under the name Wi-Fi Display under Network Adjustments. If the option never appears after the upgrade, then your model does not support the technology at the hardware level.

Solving Miracast Connectivity Problems on Xiaomi TV

Even if you turn on Miracast correctly, you can have common mistakes: the TV is not on the list of devices, the broadcast is interrupted or the image is slowed down, and let's look at the most common cases and how to fix them.

Problem 1: The TV doesn’t appear in the list of available displays

• 🔄 Reboot both devices — sometimes the banal reboot of your TV and smartphone/PC helps.
• 📶 Check Wi-Fi frequency – if the TV only supports 2.4 GHz and the router is running in 5 GHz mode, connect to the 2.4 GHz network.
• 🔍 Reset network settings on your TV: Settings → Network → Reset network settings.

Problem 2: The picture is slowing down or tearing

Problem 3: No sound when broadcasting

If there is an image, but no sound is transmitted:

1. Check if the sound on the TV is turned off (Mute button on the remote).
2. On a source device (like Android), open the notification bar and make sure the sound is being transmitted to Xiaomi TV, not the smartphone speakers.
3. On Windows: Go to Sound Settings → Output Device and select TV.

💡

If the broadcast is permanently interrupted, try to reduce the distance between the TV and the source device to 3-5 meters. Walls and furniture can interfere with the Wi-Fi Direct signal.

Optimization of broadcast quality: resolution, frame rate, sound

By default, Miracast on Xiaomi TV can stream an image at 1080p@30Hz, but on supported models you can improve the quality.

Setup of permission for Android

• 📱 Open Settings → Connections → Screen broadcast.
• 🔧 Click on the three dots in the upper right corner and select Broadcast Settings.
• 🎯 Set the maximum resolution (e.g., 1920×1080 or 3840×2160 if the TV supports 4K).
• 🔄 Reconnect to the TV.

Setup on Windows 10/11

1. Press Win + P and choose Expand or Duplicate.
2. Go to Screen Settings → Additional display settings.
3. Select a Xiaomi TV and set a 1920×1080 resolution (or higher if supported).
4. In the Adapter Properties section, check that the refresh rate is set to 60Hz (if the TV supports).

On models Mi TV Q2 and P1 with MT9611 processor, when broadcasting in 4K@60Hz resolution, there may be a delay of up to 50 ms. For games, it is recommended to reduce the resolution to 1440p@60Hz or use a wired connection over HDMI 2.1.
