Xiaomi’s modern Smart TVs offer a wide range of multimedia capabilities, turning regular TV viewing into interactive entertainment. One of the most popular use cases is broadcasting a smartphone or tablet screen to a large display. This allows you to show photos, watch videos from online cinemas, play mobile games or hold presentations directly from a mobile device. Android TV and PatchWall provide several built-in tools to accomplish this task without buying additional equipment.
Connection process can vary depending on your smartphone operating system and the firmware version of your TV. Owners of Android and iOS devices may encounter different nuances of setting up data protocols. For stable broadcast without delay, it is critical that both devices are on the same local Wi-Fi network (2.4 GHz or 5 GHz). To understand all the intricacies of wireless and wired connection will help our detailed guide covering all current methods.
Before you go to setup, make sure your TV software is updated to the latest version. Manufacturers regularly release patches that improve the stability of Wi-Fi Direct and Chromecast. Ignoring updates can cause some features to work incorrectly or not at all on the menu. Let's look at the main ways that will allow you to start streaming content in minutes.
Use of the built-in Miracast (Wireless Display) function
Miracast is the wireless media standard and is supported by most modern Xiaomi TVs. On PatchWall devices, this feature is often called Wireless Display or Wireless Display. It allows you to stream an image in real time, which is ideal for games or displaying an application interface. Unlike video streaming, it transmits exactly what is happening on your gadget's screen.
To activate the mode on the TV, go to the app menu and find the appropriate shortcut. If you don't see it on the home screen, check the Tools folder or use voice search for the remote. Once the application is launched, the TV will go into standby mode, displaying the device name, which will be visible in the list of available networks on the smartphone.
☑️ Checking before connecting Miracast
On the smartphone side, the process is also simple: Android owners need to lower the notification curtain and find the Translation, Smart View or Project button. iPhone users will need a third-party app, as native AirPlay can run unstable on older Xiaomi TV models without AirPlay 2 built in.
⚠️ Note: When using Miracast for games, consider possible latency (input lag). For dynamic shooters or racing, wireless connection may not be fast enough, which will affect the responsiveness of management.
The quality of the image depends on the power of the Wi-Fi router signal, and if you notice artifacts or audio desynchronization, try to get closer to the router or switch the TV to a 5 GHz network if it supports dual-band mode, which will significantly increase the channel bandwidth.
Streaming through Google Chromecast built-in
Most modern Xiaomi TVs are based on Android TV, which has built-in support for Chromecast technology. This allows you to stream content from apps directly to the TV without loading the smartphone processor. Unlike mirror display, here the phone acts as a remote control, and video is downloaded by the TV directly from the Internet, which saves battery power and ensures maximum picture quality.
To take advantage of this feature, make sure your smartphone has Google Home or the corresponding Google Play services installed. Open an app that supports broadcasting (such as YouTube, Netflix, ivi or Okko) and find the wave rectangle icon in the corner.
Select your Xiaomi TV from the list. If it's the first time, a connection confirmation request may appear on the TV screen, which you need to accept by the remote, after successful pairing, the video will play on the big screen, and the phone will have volume and rewind controls.
One of the great advantages of this method is that you can control playback from other devices, so if you're streaming a movie from your phone, you can take a tablet or another phone with the same Google account and pause the video or change the volume, which makes Chromecast technology extremely family friendly.
If the TV is not displayed on the list of available devices, check the firewall settings on the router. Sometimes the network protocols required to detect devices (mDNS) can be blocked by the security settings of the provider or the router itself, in which case you will need access to the router's admin panel to change the parameters.
iPhone and iPad (AirPlay and third-party solutions)
Apple owners often face the question of compatibility, because the Xiaomi ecosystem is based on Android. However, many new Xiaomi TV models have already received official support for the AirPlay 2 protocol. To check for this feature, go to the settings of the TV, select the Add Device or Apple AirPlay section. If you have such an option, just turn it on and your iPhone will see the TV in the control center.
There are great third-party solutions for models that don't support AirPlay natively. One of the most popular apps is AirScreen, which can be found on the Google Play Store on a TV. Once installed and launched, it emulates an AirPlay receiver, making your Xiaomi TV visible to any Apple device. The setup process takes no more than two minutes.
The algorithm of actions for connecting through third-party software is as follows:
- 📺 Run an emulator app (such as AirScreen) on your Xiaomi TV.
- 📱 Open the Control Point on your iPhone (swipe down from the upper right corner or up from the bottom).
- 🔗 Click the Screen Replay button (two rectangles) and select your TV.
- ✅ Confirm the connection if you need to enter code from the TV screen.
It is worth noting that when using third-party applications, the broadcast quality and connection stability may be inferior to native AirPlay, there may be periodic communication breaks or a decrease in the resolution of the image when the signal is bad, but this is enough to view photos and videos from the gallery.
Why can AirPlay be delayed?
Broadcasting through DLNA and media servers
The DLNA protocol is a time-tested standard for transferring media files within a home network, ideal if you want to watch a movie stored in your smartphone’s memory or a vacation photo on a big screen without using cloud services, and for that, a media player app like VLC for Android or a built-in Media Player should be installed on your TV.
A smartphone will also require a controller app. In the case of Android, it can be a built-in Translation feature in the gallery or file manager. iOS will be suitable for applications like 8player or VLC. The main condition is that both devices must be connected to the same Wi-Fi network. Open a video file on your phone, select the Translation option or DLNA icon and specify the TV.
Unlike Miracast, DLNA doesn't mirror the screen, it only transmits the file itself, which means you can fold the app on your phone, answer a call, or even turn off your smartphone screen -- playback on your TV will continue, making it extremely convenient for long-term viewing of content.
| Characteristics | Miracast | Chromecast | DLNA |
|---|---|---|---|
| Type of transmission | Screen mirroring | Streaming from apps | File transfer |
| Dependence on the phone | High (screen active) | Low (control panel) | Minimum |
| Image quality | Depends on the signal. | Original (up to 4K) | Original |
| Battery consumption | High-pitched | Low. | Low. |
In the case of DLNA It is important to consider supported file formats if the TV cannot decode a specific codec (e.g., the codec is not decoded, DTS For sound or rare video codecs, playback may not start or go without sound. In such cases, it is recommended to use players with their own codecs installed directly on the video. TV-set-top.
Wired connection via HDMI and USB-C
If the wireless connection is unstable or requires maximum image transmission without compression, the best solution is cable connection. For modern smartphones with a USB Type-C port, there are special USB-C to HDMI adapters. This method allows you to broadcast the image even without a Wi-Fi network, which is important for cottages or hotels with closed access to the network.
The DisplayPort Alt Mode feature should be hardware-implemented in your gadget’s processor. flagship models of Samsung, Huawei, Xiaomi and Sony usually have this support, whereas budget devices may not transmit a video signal through the charging port.
To connect, perform the following actions:
- 🔌 Connect the adapter. USB-C ce HDMI port-of-charge.
- 📺 Connect the adapter and TV with a conventional cable HDMI.
- 📺 Switch the signal source on the TV to the appropriate port (e.g, HDMI 1).
- 📱 The image should appear automatically; if not, check the output settings in the Screen section on your phone.
💡
Use HDMI 2.0 or higher cables if you plan to stream content in 4K HDR resolution. Older HDMI 1.4 cables may not miss a high-definition high-frame rate signal.
The advantage of wired technology is that it doesn't have any delays and it's completely independent of the quality of the wireless network, and it's ideal for presentations or games where every millisecond matters, but it's worth considering that the smartphone will run out faster if the adapter doesn't have an additional port to charge.
Problem Solving and Diagnostics
Even if you set it up properly, you can have a problem. The most common problem is that the TV can't see the phone or vice versa. 90% of the time, it's because the devices are connected to different networks. For example, the phone is sitting on the guest Wi-Fi Guest network, and the TV is on the main, or one of the devices is using mobile Internet. Always check the network name in the settings.
Another common reason is outdated software. Go to your TV settings, look for the Device section. → Update the system and check for new versions. On the smartphone, you should also update the applications through which the streaming is going, and Google Play services.
⚠️ Warning: Antivirus programs or memory cleaners on your smartphone can block device search on your local network. If the connection fails, try temporarily disabling protection or adding a broadcast app to the exceptions.
If there is an image but no audio, check the audio output settings in the app from which the broadcast is coming. Sometimes the default sound remains on the phone and needs to be manually switched to the TV via the volume menu or Bluetooth/Audio settings.
💡
Routers can “forget” active DHCP-leases or clog up the cache, which prevents devices from mapping correctly on the network.
