How to turn Miracast on your Xiaomi Mi TV 4S: A complete guide to solving common bugs

Miracast technology allows you to broadcast a smartphone, tablet or laptop screen to the large screen of a Xiaomi Mi TV 4S without wires — just support for the standard on both devices is enough. However, many users face difficulties when connecting for the first time: the function is not on the menu, devices do not see each other, the image slows down. In this article, we will discuss not only the basic steps of Miracast activation, but also the nuances of settings for stable operation, as well as solving common problems.

The Mi TV 4S (unlike the newer Xiaomi models) is that Miracast support is implemented through the PatchWall branded shell, not through the standard Android TV menu. This means that the path to settings may be different from the usual one, and some options are hidden deeper. In addition, the broadcast quality depends on the version of the TV firmware and the source device – we will also talk about this in more detail.

If you've tried Miracast before and you've failed, don't be quick to blame the technology. 80 percent of the time, the problem is network setups, outdated software, or protocol conflicts, and we've put together checklists and step-by-step instructions to help you avoid common mistakes.

What is Miracast and why it is better than other broadcasting methods

Miracast is a wireless video and audio transmission standard over Wi-Fi Direct that does not require a router connection. Unlike alternative technologies (like Google Cast or Apple AirPlay), it works directly between devices, which reduces latency and improves stability. The main advantages of Miracast for Xiaomi Mi TV 4S:

• 🔌 No router dependency – the connection is established directly between the TV and the smartphone / laptop.
• 🎮 Minimum latency (around 30–50ms) is critical for gaming or watching live video.
• 📶 It works without internet – it’s enough for both devices to support Wi-Fi Direct.
• 🔒 Secure connection with encryption WPA2, precludes interception of data.

Miracast does have limitations, such as not supporting high-resolution streaming of secure content (such as Netflix or Disney+ due to DRM), and Mi TV 4S with firmware older than 2021 may have problems connecting Android 12+ devices due to changes in the Wi-Fi Direct protocol.

By comparison, Google Cast (used in Chromecast) requires a connection to a single Wi-Fi network but supports more applications, and AirPlay only works in the Apple ecosystem. Miracast is versatile - it is built into most Android devices, Windows (starting with 8.1) and even some Linux models.

Preparation of the Xiaomi Mi TV 4S to connect via Miracast

Before you turn on Miracast, you need to make sure that the TV is ready for wireless broadcasting.

1. Update the firmware. Mi TV 4S versions older than 1.7.65 may not have Wi-Fi Direct options. Check the current version at Settings → About TV → Software version. If the update is available, install it through Settings → System Update.
2. Reset network settings (if you have previously had connection problems). To do this, go to Settings → Network and Internet → Additional → Network Reset.
3. Turn off VPNs and proxy on your TV if they are active – they can block device detection.
4. Make sure the TV is not connected to 5GHz Wi-Fi. Miracast on the Mi TV 4S performs better in the 2.4GHz band.

A critical caveat: if your TV was previously connected to Miracast, but now the feature is gone, check if the developer mode is disabled. On some firmware, the Wi-Fi Direct option is hidden when ADB is activated.

Step-by-step: how to turn Miracast on Xiaomi Mi TV 4S

Now, to turn the function on directly. On the Mi TV 4S, the path to Miracast settings may vary depending on the PatchWall version. We'll look at both.

Method 1: Through the screen menu (firmware 2020-2023)

1. Turn on the TV and go to the main screen of PatchWall.
2. Open the settings (cog in the upper right corner).
3. Select Connections and Sharing (or Network and Internet on older versions).
4. Scroll down and find Wireless Display or Miracast.
5. Activate the switch. The TV will start looking for available devices.

Method 2: Developer Mode (if the option is hidden)

If Miracast is not on the menu, try turning it on through the hidden settings:

1. Activate Developer Mode: Go to Settings → About TV and click on the Software Version 7 times.
2. Go back to the main settings menu and open a new section for developers.
3. Find the Wireless Display option and turn it on.
4. Return to Connections and Sharing – Miracast should appear.

If you don't get the option after that, check if it's disabled at the system level.

Click on the remote: Menu → Settings → All Settings → General → Network → Wi-Fi Direct

💡

If the TV doesn't find the device to connect, try rebooting both. On your Android smartphone, also check if Visibility for All Devices is enabled in the Wi-Fi Direct settings.

Setting up Miracast on the source device (smartphone, laptop)

Miracast is a two-way technology, so it's not just a tv setup that you need to set up, but it's also a setup on the device you're streaming the screen from.

Android (smartphones and tablets)

1. Open Settings → Connections → Wi-Fi Direct or Smart View (on Samsung).
2. Turn on device search. Your Xiaomi Mi TV 4S (usually displayed as MiTV-XXXXX) should appear on the list.
3. Select the TV and confirm the connection. The pairing request will appear on the TV screen — click Confirm.

On some devices (such as Xiaomi Redmi or POCO), the option may be called a Wireless Display or Cast. If the feature is missing, check if your smartphone supports Miracast (a list of compatible models can be found on the manufacturer's website).

Windows 10/11

1. Press Win + K or open Settings → System → Display → Connect to a wireless display.
2. Choose Xiaomi Mi TV 4S from the list of available devices.
3. Confirm the connection on the TV.

If the TV doesn't appear on the list, update the Wi-Fi adapter drivers on your laptop or PC.

1. Open Device Manager (Win + X → Device Manager).
2. Find Network Adapters, select your Wi-Fi module and update the driver.

macOS and iOS

Apple devices don't support Miracast, instead using the proprietary AirPlay protocol. But there's a workaround: you can install AirScreen on the Mi TV 4S and stream the screen through it, and it's worse than native Miracast, but it's a good option for presentations or videos.

Common Problems and Their Solutions

Even if you set up the Miracast connection correctly, it can be unstable, and we've collected some common bugs and ways to fix them.

If after connecting the screen of the smartphone is displayed with black bars or incorrect resolution, try to manually set the parameters of the broadcast:

1. On the TV, go to Settings → Screen → Resolution.
2. Select Auto or manually set 1920×1080 at 60 Hz.

⚠️ Note: Some of the Mi's firmware TV 4S Updated to PatchWall 3.0+ Miracast may work unstable with Android 13 devices+. In this case, try to roll back to the previous version of the software or use alternative streaming methods (for example, Google Cast through the YouTube app or Google Home).

Streaming Optimization: How to Improve Quality and Reduce Delays

To stream Miracast as smoothly as possible, follow these recommendations:

• 📶 Place the devices closer together (within 3-5 meters) and walls and obstacles degrade the signal.
• 🔄 Use the 5GHz band for Wi-Fi Direct (if the TV supports).It's less congested and provides more bandwidth.
• 🎛️ Reduce the broadcast resolution to 1280×720, if there are lags.
• 🔌 Connect the TV to the network via cable (if you are streaming content from the Internet.

For games or high bitrate video (e.g. 4K), it is best to use alternative connection methods:

• HDMI-cable – minimum delays, maximum quality.
• Google Cast – if the content supports Chromecast (YouTube, Netflix).
• Steam Link – for broadcasting games from a PC (requires installing the application on the TV).

If you are streaming a screen from a Xiaomi/Redmi smartphone, activate Game Turbo mode in the battery settings – this will reduce delays and prevent connection breaks.

💡

For stable performance of Miracast on Xiaomi Mi TV 4S it is critical to use firmware no older than 2021. on earlier versions there may be problems with compatibility with Android 12+.

Miracast for Xiaomi Mi TV 4S

If Miracast is not suitable (for example, due to device incompatibility or delay issues), consider alternative streaming methods:

For PC games to be streamed to the Mi TV 4S, Parsec or Moonlight (for the NVIDIA GPU) are the best solution, using their own protocols with minimal delays, but require computer-side configuration.

⚠️ Note: When using third-party broadcasting apps (such as ApowerMirror or TeamViewer) on Mi TV 4S There may be a problem with sound due to limitations. DRM. In this case, connect external speakers or sound panel through HDMI ARC or.
