Modern smart TVs from the company Xiaomi They offer users a wide range of multimedia interaction options, and one of the most popular features is wireless content streaming. Connecting your smartphone to a large screen allows you to conveniently view photos, videos, play games, or present presentations without the need for cables. The entire process is based on the local network. Wi-Fi, which makes the connection stable and fast when the equipment is configured correctly.
Before proceeding with specific actions, you need to make sure that both devices—the mobile gadget and the TV—are working correctly and are within a strong signal reception area. It is critical that both devices are connected to the same Wi-Fi router access point, as working via mobile Internet (3G/4G/5G) in standard Miracast scenarios is not possible. Operating system interface Android TV, installed on TVs Mi TV, optimized for receiving high-definition streaming video.
There are several ways to establish a wireless connection, each with its own characteristics and suited to different needs. You can use built-in operating system features, third-party apps, or specialized data transfer protocols. The method you choose depends on your phone model, operating system version, and the type of content you plan to stream to your screen.
Preparing equipment and checking the network
The first step to successfully synchronizing devices is to carefully prepare your network environment. Make sure your router supports the standards 802.11n, 802.11ac or newer, as older protocols may not provide sufficient bandwidth for high-definition video. If your router is dual-band, it's recommended to connect both devices to the 5 GHz network to minimize latency and improve image quality.
Check that your TV software is up to date. Xiaomi Mi TVManufacturers regularly release updates that fix wireless module bugs and improve compatibility with new smartphones. To check for updates, go to the TV settings menu and select Settings → About device → System update and start searching for new software versions.
It's also worth paying attention to your smartphone's power-saving settings. Aggressive battery-saving algorithms can block background network services needed to maintain a constant connection to the TV. Temporarily disable power-saving mode or add the streaming app to the exceptions list.
Using the built-in "Broadcast" function (Miracast)
The most common and universal way of connection is using technology Miracast, which is built into most modern Android smartphones and TVs Mi TVThis technology allows you to mirror your phone's screen to your TV in real time, transmitting everything that's happening on your mobile device's display. Activating this feature on your TV typically requires no configuration; it works in the background.
On your smartphone, open the quick settings panel (the drawer) and look for the "Cast," "Smart View," "Wireless Monitor," or "Projection" button. The function name may vary depending on the phone manufacturer and OS version. MIUI or ColorOSOnce activated, the phone will begin searching for available devices on the Wi-Fi network.

It's important to note that for Chromecast to work, both devices must be logged in with the same Google account or be on the same local network without AP Isolation. If you're using a guest Wi-Fi network, casting may not be possible due to router security restrictions.

Solution and troubleshooting
Despite the simplicity of the technology, users may encounter connection issues. One of the most common causes is a mismatch of Wi-Fi frequency bands. If your router broadcasts 2.4 GHz and 5 GHz networks with different names (SSIDs), make sure your phone and TV are connected to the same network and not to different bands.
Another common issue is antivirus software or a firewall on your phone, which can block incoming connections from the TV. Try temporarily disabling the protection or adding the TV to the list of trusted devices. It's also worth checking whether AP Isolation mode is enabled on your router, which prevents devices on the same network from seeing each other.
⚠️ Attention: If your TV stops detecting your phone after updating your router, try rebooting the router by unplugging it for 10-15 seconds. This will clear the DHCP cache and reassign IP addresses, which often resolves the device visibility issue.
In some cases, resetting your smartphone's network settings can help. This will delete saved Wi-Fi passwords and Bluetooth settings, but may also resolve software errors interfering with the connection. After resetting, you'll need to re-enter your Wi-Fi password.
What should I do if the audio lags behind the video?
Audio lag often occurs when using Miracast. Try lowering the output resolution on your phone or switching to Chromecast if the app supports this protocol.
Frequently Asked Questions (FAQ)
Why doesn't Mi TV see my phone in the list of devices?
Most likely, the devices are connected to different Wi-Fi networks (for example, one to a guest network and the other to the main network) or client isolation is enabled on the router. Also, check if your phone is in Airplane Saving mode or has an ad blocker, which could be interfering with detection.
Is it possible to connect a phone to a TV without the Internet?
Yes, if your router is distributing a local Wi-Fi network, internet access is not required for Miracast or DLNA to work. The main thing is that devices can "see" each other within the router's local network.
How to reduce lag when playing games on TV via phone?
For gaming, it's best to use "Game" mode in your TV's picture settings, if available. Also, make sure your phone is connected to a 5 GHz network and close any background apps that consume data.
Does my old Xiaomi TV support AirPlay?
AirPlay 2 support has been added to newer models and firmware updates. If you don't see AirPlay in your TV settings, your model may be too old or require a firmware update via a USB drive from the manufacturer's website.
