Xiaomi’s modern smart TVs offer access to a wealth of entertainment content, but the first launch often raises questions for new owners. The right setup is not just plugging in, but a set of actions to unlock the full potential of Android TV. From choosing the right diagonal to fine-tuning the screen resolution, each step affects image quality and interface speed.
In this article, we will look at all the ways your screen connects to the outside world, how to set up a Wi-Fi connection for stable 4K streaming, how to stream an image from a smartphone, and what hidden features are available in the engineering menu. A competent initial configuration will save you from lags and compatibility problems in the future.
Primary setup and connection to the Wi-Fi network
Once you unpack and install the TV on a stand or wall bracket, you need to initialize the system. When you first turn on MIUI for TV, you will be asked to choose a language and region. The critical point is the Internet connection, because without it, you can not activate most of the functions of smart TV and synchronize time.
Use the remote to navigate the menu. Go to Settings → Network and Internet. The system will offer a list of available wireless networks. Find your router's name in the list and enter your password. To ensure maximum data transfer speed, especially if you plan to watch movies in high resolution, it is recommended to use the 5 GHz band.
If the signal is weak or the network is overloaded, the TV may not work as well, and alternative connectivity options that provide more stable data flow without packet loss should be considered.
💡
Use an Ethernet cable (LAN) to connect your TV directly to your router if maximum stability and speed are important, such as watching heavy 4K HDR content.
⚠️ Note: When entering a Wi-Fi password, carefully check the letter register. An error in one character will result in denial of access, and the system may not immediately report the cause of the failure.
After a successful connection, the system will offer a software update. Don't ignore this step, as new patches often contain patches for Wi-Fi and Bluetooth modules, which directly affects the quality of the connection.
Use of a wired LAN connection
While wireless technology has advanced, physical connectivity via Ethernet cable remains the gold standard for stability, especially for gigabit port models that can deliver speeds that many Wi-Fi adapters cannot afford in noisy ether.
To connect, you'll need a UTP Cat 5e or higher cable, one end inserted into the router's free port, and the other end into the LAN connector on the back or side of the TV, and the system automatically detects the wired connection and prioritizes it over the wireless one.
☑️ Checking the network connection
The benefits of this method are obvious: no delays in management, stable bitrate during streaming and independence from interference from neighboring routers, which is ideal for organizing a home media center.
| Parameter | Wi-Fi 2.4 GHz | Wi-Fi 5 GHz | LAN (Cable) |
|---|---|---|---|
| Stability | Low. | Medium | Tall. |
| Max, speed. | up to 50 Mbps | up to 300 Mbps | up to 1000 Mbps |
| Delay (Ping) | Tall. | Medium | Minimum |
| Convenience | High. | High. | Requires cable laying |
Broadcasting of the smartphone screen (Cast and Miracast)
One of the most popular features is the ability to display images from a mobile device to a large screen, and in the Xiaomi and Android ecosystem, this is implemented through Google Cast and Miracast technologies, which allows you to show photos, videos or even games in real time.
To use the Cast feature, make sure your smartphone and TV are connected to the same Wi-Fi network. Open an app that supports broadcasting (like YouTube or Netflix) and click on the wave rectangle icon. Select your Android TV from the device list.
If you want to stream the entire screen of your smartphone, including menus and games, use the Translation feature in the Android notification curtain or Screen Replay in iOS.The TV must support the Miracast protocol, which is relevant for most modern models.
Sometimes the device is not automatically located. In this case, check the router settings: AP Isolation should be disabled, as it prevents devices on the network from seeing each other.
Connecting external devices via HDMI and USB
Xiaomi TV serves as an excellent display for gaming consoles, PCs, Blu-ray players and sound systems. HDMI ports provide high quality video and audio. For next-generation gaming consoles (PS5, Xbox Series X), it is important to use ports that support HDMI 2.1 or at least 2.0 for 4K at 60 FPS.
When you connect your computer, you can have zoom problems, so that you can take up the entire screen without cutting edges, look up the image settings in the TV menu and select Scan Only or Just Scan mode, which will remove the extra bezels.
Settings → Image → Image Size → Scanning OnlyUSB-You can connect movies or peripherals to ports, and note the color labeling of the ports: blue connectors are usually standard. USB 3.0 and allow faster reading of large files.
⚠️ Note: Do not connect hard drives that require external power to USB-TV port without active USB-This can cause system instability or damage to the port.
Installation and configuration of applications
Android TV provides access to the Google Play Store, where you can find thousands of apps, from online cinemas to file managers. To install, just select the app you want and click "Install."
But not all applications are optimized for remote control. USB-You can use a mouse or a remote app on your smartphone, and that's going to make it easy to control the interface that's originally designed for the touchscreen.
How to install apps not from Google Play?
It is recommended to install a quality file manager and cache cleaning application immediately, which will help keep the system clean and avoid slowing down the interface over time.
Setting up Bluetooth devices
The built-in Bluetooth module allows you to connect wireless headphones, gamepads, keyboards and sound systems, which makes watching movies at night a comfortable process without disturbing others.
Go to Settings → Remotes and Accessories → Add Accessory. Put your device (earphones or gamepad) in pairing mode. The TV will start searching and in a few seconds display the name of the device in the list of available.
When connecting a gamepad, make sure it supports XInput mode or has an Xbox controller emulation, as compatibility with PlayStation’s DualShock can be limited without third-party drivers.
💡
To minimize audio delay when using Bluetooth headphones, choose aptX Low Latency codecs if both devices support them.
Solution and diagnosis
You can experience situations when the TV doesn't see the network or loses connection during operation. First, reboot the router and the TV. Often the problem lies in a crowded cache. DNS conflict IP-address.
If the problem persists, try to change it. DNS-servers in the network settings to public, for example, from Google (8.8.8.8) or Cloudflare (1.1.1.1). This often helps if the provider blocks certain services or slowly processes requests.
⚠️ Note: Resetting your network settings to factory settings will remove all saved Wi-Fi passwords. Use this option only if other methods have not helped.
It’s also worth checking the date and time. Incorrect timings can lead to security certificate errors, which will cause many apps (YouTube, Netflix) to stop running, claiming that there is no Internet connection even though the network is working.
