Modern smartphones like the Xiaomi Redmi 10 have high-resolution screens that are perfect for viewing content. However, even a high-quality matrix is not always able to replace a large TV screen, especially when you want to show friends photos from a vacation or run a movie in a cinematic format. Fortunately, wireless image transfer technology has long ceased to be a complex procedure that is only available to engineers, and now is available to everyone.
In this article, we will discuss how to set up your smartphone screen to your TV, the MIUI system, the capabilities of Google Chromecast and third-party applications that will help solve the problem if standard methods do not work, learn about the nuances of connecting over Wi-Fi and cable, and understand why sometimes there is a delay in image.
Before you start setting up, make sure your devices are ready to sync. A stable connection is a key success factor, without which quality picture is impossible. If you plan to watch high-resolution video, the signal interruptions will be particularly noticeable and can ruin the viewing experience.
Preparation of equipment and Wi-Fi network
The first step to a successful broadcast is to properly organize the local network. Your Xiaomi Redmi 10 and TV must be on the same Wi-Fi network. This means that if the router is broadcasting at 2.4 GHz and 5 GHz, both devices must be connected to one of them, although modern routers often combine them under the same name.
Check the software version on your TV. Manufacturers regularly release updates that improve data protocols and fix compatibility errors. Go to your TV settings menu and find Support → Software Update to make sure you have the latest available firmware installed.
⚠️ Note: If your router is set to guest mode or has customer isolation (AP Isolation, devices won't see each other. Temporarily disable this feature in router settings for connection procedure.
Also consider the distance between the router and the receiver. Walls and appliances can cause interference, especially at 2.4 GHz. For best results, it is recommended to have the devices in line of sight from the access point or use a wired connection for the TV, if possible.
Use of the built-in Translation function in MIUI
Xiaomi smartphones come with its own MIUI shell, which includes a handy image display tool based on the Miracast standard, which is supported by most modern TVs, even if they don’t have an Android TV built in. You don’t need to install additional apps to get started.
Open the notification curtain, swipe from top to bottom, and find the Translation icon. If it's not on the first page, click on a pencil or three menu editing dots and add this element. Once activated, the system will start searching for available devices within the network range.
☑️ Checking before connection
When the TV appears on the list, click on it. The TV screen may have a request to confirm the connection — use the remote to allow access. After that, the image from your Redmi 10 is completely copied to the big screen.
It's important to understand the difference between simply streaming a screen and sending content. In live streaming mode, your smartphone actually turns into a remote control, and any actions you take, including incoming notifications, will be visible on the TV, so you'd better turn on Do Not Disturb mode before you start watching a movie.
Broadcasting via Google Home and Chromecast
If your TV is running Android TV or has built-in Chromecast support, the most effective way to do this is to use the Google ecosystem, a method that often provides a more stable picture and lower latency compared to standard Miracast, especially when streaming videos from apps.
To start, make sure your Xiaomi Redmi 10 has a Google Home app installed. It's often preinstalled, but if it's not, download from the Play Market. Open the app and find your TV in the device list. Click on the device icon, and then select the Translate screen button.
| Parameter | Miracast (Translation) | Google Cast (Chromecast) | HDMI Cable |
|---|---|---|---|
| Type of connection | Wireless (Wi-Fi Direct) | Wireless (Local area network) | Wired |
| Delay. | Medium/High | Low. | Absent. |
| Quality. | Depends on the signal. | High (up to 4K) | Maximum. |
| Battery consumption | High-pitched | Medium. | Charging the phone |
The advantage of Google Cast is that it can be smart in encoding the stream, so the TV can download content from the Internet, and the phone can only manage the process, saving battery life and reducing the workload on the smartphone processor, but both devices require an active Internet connection, not just a local network.
Application of third-party broadcasting applications
In some cases, regular funds may not find a TV, especially if it is a model of old years of release or specific brands, here come to the rescue universal applications-translators that use their own algorithms for detecting and encoding video stream.
One popular solution is the TV Cast app or Web Video Caster, which allows you to broadcast not only the entire screen, but also specific video files or browser tabs. Once you install the application on Xiaomi Redmi 10, you also need to install a companion app (if required) or simply select your TV from the list within the program.
Many users have noted that third-party apps are better at handling video formats that are not supported by the native TV player, and that they can stream audio tracks separately, which solves the problem of no sound when playing certain files.
⚠️ Warning: Free versions of broadcast apps often contain intrusive ads that may overlap the image on the TV.
There are also apps that turn your phone into a media server (DLNA), in which case you don't duplicate the screen, you send the file to play, and it's ideal for watching heavy movies in high bitrate when wireless screen duplication causes jerks.
Wired connection via USB-C and HDMI
For those with maximum quality and zero latency, wireless methods may not work, but there’s an important technical nuance: budget and mid-budget smartphones, including the Xiaomi Redmi 10, often feature a USB 2.0 Type-C port that doesn’t support direct video transmission.
This means that a normal USB-C to HDMI adapter won't work. To display the image over the cable, you'll need a special adapter that uses DisplayLink technology. These adapters contain an embedded chip that processes the video signal programmatically, through an application driver.
Why isn't the normal cable working?
The process of connecting is as follows: you connect the DisplayLink adapter to your phone, install the appropriate application (for example, DisplayLink Presenter), and only then connect the adapter to the TV via HDMI.
While this method requires the purchase of additional hardware, it ensures a stable picture without interference from microwave ovens or neighbouring routers, and when wired, the phone can charge simultaneously if the adapter has a power port.
Elimination and optimization of quality
Even with a perfect setup, you can have problems: you can have audio and video out of sync, you can have low resolution, you can have periodic hangs, and most often, you can have Wi-Fi congestion, and if you have torrents or online games on your network at the same time, you can't have enough to stream.
Try lowering the resolution of the streamed image in the settings of the phone or the broadcast app, and rebooting the router and cleaning the cache of Google Play Services on the smartphone also helps, and make sure that the phone does not run background processes that consume traffic.
💡
To reduce latency when playing, use Game Mode on your TV, which disables the extra post-processing of the image, speeding up the response.
If the sound is coming and the image is not, check the HDCP settings. This is content copy protection. Some older TVs or adapters may not support the required protocol versions, which will cause streaming services (Netflix, Disney+) to display a black screen instead of a movie.
💡
The quality of wireless broadcasting is 90% dependent on the speed and stability of your Wi-Fi router, not the power of your smartphone.
