The modern smart home ecosystem is built around convenient interaction between devices, and the smartphone-TV bundle plays a key role here. Xiaomi and Redmi owners often strive to bring their favorite video or game to the big screen to get the most out of the content. It really changes the experience of media consumption, turning an ordinary evening into a home theater.
The process of syncing devices has become much easier with the release of new versions of the shells MIUI and Android TV. Now you do not need to be an IT expert or buy expensive additional equipment to broadcast.
There are several proven methods, each with its own advantages depending on your goals: you can use wireless protocols to quickly transfer photos or choose a wired connection for stable picture in games, and we will analyze each option in detail so you can choose the best one.
Preparing devices for synchronization
Before any manipulations are initiated, it is necessary to make sure that both devices are in the same network conditions, a fundamental requirement for most wireless data protocols to work, and if gadgets can’t see each other, this is often the problem.
Make sure your smartphone and Smart TV are connected to the same Wi-Fi network. It's important that it's the same network, not different router frequencies (2.4 GHz and 5 GHz), although modern routers often combine them under the same name. If you have a dual-band router, try switching both devices to the same frequency for better compatibility.
It's also worth updating the software on both devices to current versions. Manufacturers regularly release patches that improve the stability of the Miracast protocol and the built-in broadcast functions. Go to the system settings and check for updates.
Make sure the device detection feature is enabled on the TV. Some Xiaomi Mi TV models with Android TV shells need to activate the connection standby mode. Usually it is on by default, but after resetting the settings could be deactivated.
Wireless broadcasting through built-in functions
The easiest and most popular way to do this is to use the native Translation or Cast function, which requires no third-party software and works on most current models, and is based on the Miracast standard, which is supported by almost all Android smartphones.
To start the process, lower the notification curtain on your phone and look for the Transaction, Transfer or Cast icon. On your TV, you may need to run an app at this time, which is often called Wireless Display, Miracast or simply Translation. After searching for devices, select your TV from the list.
⚠️ Note: When using the wireless method, small image delays are possible, which is critical in dynamic games, but imperceptible when watching videos or photo albums.
If standard search doesn't work, try using the Xiaomi TV app (formerly Mi Remote) or the built-in functionality in the gallery. In many cases, the system will offer available displays when you try to run a video. The quality of the picture depends on the speed of your Wi-Fi router.
💡
To reduce latency when broadcasting wirelessly, place the router as close to the TV as possible or use 5 GHz if both devices support it.
It's worth noting that some apps, like Netflix or YouTube, have their own broadcast button inside the interface, and if you click on it, you tell the TV to play content directly from the Internet, bypassing the phone, which saves battery life on the smartphone.
Using Chromecast technology
Xiaomi TVs often run on Android TV, which has built-in support for Google Chromecast technology, which allows you to stream content from apps directly to the TV screen with high quality, a method different from Miracast in that the phone is only a remote control.
To take advantage of this, make sure that the smartphone has Google Home installed. It is necessary for initial configuration, although in many cases, simply having Google Play services is enough. Open the application that supports.cast (YouTube, Google Photos, Chrome browser), and click on the icon of the rectangle with waves.
- 📺 Open the control menu in the application on the phone.
- 📡 Select your Xiaomi TV from the list of available devices.
- ▶️ Content will start playing on the big screen automatically.
The advantage of this method is that you can use the phone for other tasks while the video is on the TV, and the Chromecast also provides a more stable connection and better image quality, since the TV loads the stream itself, which is especially important for 4K video.
What to do if Chromecast doesn’t work?
If the router is overloaded, buffering pauses are possible, and unlike mirroring the screen, here the phone is not transmitting a video stream, but only giving a command to the TV where to get it.
Wired connection through HDMI-cable
For users who want maximum stability and no delays, wired connectivity is ideal, especially for gamers or when watching heavy high-resolution video, and you'll need a special adapter because you can't directly insert the cable into your smartphone.
Depending on your phone, you will need an adapter. USB-C to HDMI or MHL-Adapter. Not all Xiaomi smartphones support wire output, but it's worth checking out your model's specifications.
☑️ Checking before buying the cable
The connection process is elemental: insert the adapter into the charging connector of the phone, and HDMI-Connect the adapter and the TV. Then, on the TV remote, press the signal source select button (Input or the square icon with the arrow) and select the appropriate port. HDMI.
The image will appear automatically. In the settings of the phone, you can see a projector menu, where you can choose to work: mirror display or extended desktop. The wired connection ensures that there is no interference from microwave ovens or neighboring Wi-Fi networks.
Comparison of connection methods
The way you connect depends on your current tasks and the equipment you have, and to make it easier for you to decide, we've created a comparison table of the main characteristics of each method, which will help you weigh the pros and cons.
| Parameter | Wi-Fi (Miracast) | Chromecast | HDMI Cable |
|---|---|---|---|
| Stability | Medium | Tall. | Maximum |
| Delay (Latency) | Got it (0.5-2 sec) | Minimum | Absent. |
| Image quality | Depends on the network. | Up to 4K HDR | Up to 4K/8K |
| Battery charge | Get down fast. | Savings in expenditure | Can charge (with hub) |
As you can see from the table, the cable is the best for gaming, and the Chromecast is the best for watching YouTube. Wireless mirroring is universal, but it can fail when you have a bad signal. Choose a tool for a specific situation.
And there's format compatibility, too. Some older TVs may not support certain codecs when broadcast from the phone, and in these cases, wired connectivity often solves the problem, because the smartphone itself is decoding.
Addressing common problems
Even if you follow all the instructions, you can have technical difficulties, and you often have a phone that can't see the TV, and you can try rebooting both the devices and the router first, and it's a simple but powerful piece of advice that solves 80 percent of the network problems.
If the problem persists, check the firewall settings on the router. Sometimes security features isolate devices from each other, preventing local data exchange. Make sure that DLNA or Local Network is enabled in the router settings.
⚠️ Warning: Antivirus apps on your phone can block device search on your local network. Try temporarily disabling protection or adding a TV to exceptions.
If you have problems with picture quality when wirelessly connected, try lowering the resolution of the output image in your phone settings, and closing the background apps that consume traffic can also help. If nothing helps, reset your network settings on your TV via the Settings menu. → Network → Reset.
💡
The main reason for connection problems is finding devices on different subnets or using guest Wi-Fi mode, which isolates customers.
