Modern smartphones have powerful screens, but you often want more to watch movies or games. Big screen display is not just a convenience, it’s a necessity for a comfortable leisure. Owners of Xiaomi and Redmi equipment have several options for this task, from standard functions to specialized cables.
In this article, we'll take a look at all the available methods, including wireless protocols and wired connectivity, how to set up a stream without delay and what to do if the TV can't see the phone, and if you set up the right way, you can enjoy high-resolution content without the hassle of it.
A variety of TV models and MIUI or HyperOS shell versions can make adjustments to the process, but the basic principles remain the same for most devices, and we will look at the nuances that will help avoid common connection errors.
Wireless broadcasting through built-in functions
The easiest way is to use the built-in Translation or Wireless Display feature, which is based on the Miracast standard that most modern Smart TVs support, and you don’t need to install additional apps if the TV is on the same Wi-Fi network.
To start the process, lower the notification curtain and find the Translation icon. If it's not on the first screen, click the panel edit button (usually a pencil square or three dots) and add a widget. Once activated, the phone will start searching for available devices within network range.
💡
Make sure that both the phone and TV are connected to the same Wi-Fi network (2.4GHz or 5GHz), or else the search may not be successful.
When your TV appears on the list, just tap the name of the TV, and you may see a request for confirmation of connection on the TV screen, which you need to accept by the remote, and then the image from the mobile device is fully duplicated on the large screen.
- 📺 Open the Quick Access settings on your phone.
- 🔍 Select the "Translation" or "Cast" option».
- 📡 Wait for the name of your TV to appear.
- ✅ Confirm the connection on both devices.
It's worth noting that when using Miracast, the phone can get hot because it's actively transmitting the video stream, which is normal, but if you're planning a long browsing, it's better to have the device vented or the case removed.
Using Google Chromecast technology
Many modern TVs have built-in support for Google Cast, an alternative protocol that often works more stable than Miracast, especially when streaming videos from apps.
Launch the Google Home app and find your TV in the device list. Click on the device icon and then select the Translate screen button. The system will prompt you to start the process, after which the phone screen will appear on the TV.
The advantage of this method is that you can actually manage content, so you can fold the app on your phone, and the video will continue to play on your TV while you're responding to messages, and that frees up the resources of your smartphone for other tasks.
However, it should be noted that the quality of the image may depend on the speed of the Wi-Fi router. If the network is congested, artifacts or desynchronization of the sound may be possible, in which case it is recommended to restart the router or get closer to it.
Connection via HDMI cable and adapters
If wireless connectivity is not possible or unstable, a wired method comes to the rescue. You will need a USB-C to HDMI adapter. It is important to understand that not all Xiaomi phones support video output via USB, as you need a port of version 3.0 or higher with support for MHL/Slimport.
The connection is simple: insert the adapter into the phone charging socket and the HDMI cable from the TV in it. Switch the signal source to the TV (Input or Source button) to the appropriate port. The image should appear automatically.
Why isn't the cable working?
The advantage of this connection is that there are no delays and dependence on Wi-Fi. You can play games with minimal ping or watch videos in 4K without buffering.
| Type of connection | Stability | Quality. | Delay. |
|---|---|---|---|
| Wi-Fi (Miracast) | Medium | High. | There is. |
| Google Cast | Tall. | Maximum. | Minimum |
| HDMI Cable | Perfect. | No compression. | No. |
When using the cable, carefully monitor the heating of the smartphone. Prolonged operation in video output mode can lead to the processor trottling if the device does not have active cooling.
Smart TV apps from Xiaomi and other brands
TV makers often offer their own synchronization solutions, such as Mi TV and Redmi TVs, which are best suited to Mi Remote or the built-in Mi Drop (now ShareMe) feature for file transfer, but screen-based solutions are better suited to one-size-fits-all solutions.
If you have a TV from another brand, such as Samsung or LG, you can try their proprietary applications, which often support the DLNA or AirPlay 2 protocol.
☑️ Checking before connection
In some cases, you need to manually adjust the resolution. Go to Settings → Screen → Resolution and select the mode supported by the TV, usually 1920×1080 or 3840×2160.
Remember that third-party apps can consume more power. If you use live streaming often, it makes sense to keep your phone charging, and check if your phone is running a power saving mode that may limit background activity.
Solving Connection and Delay Problems
A common problem is desynchronizing audio and video, which can be due to low Wi-Fi speeds or congestion, and try switching to a 5GHz network if your router and TV support this standard.
Another common difficulty is that the phone can't see the TV. Make sure the router doesn't have AP client isolation enabled. This security feature prevents devices inside the network from seeing each other, which blocks Miracast and Chromecast from working.
⚠️ Note: If you are connected through HDMI no sound, check the audio output settings in the engineering menu or in the developer settings by switching the channel to HDMI.
Also worth checking out is the TV's firmware updates, with manufacturers often releasing patches that improve compatibility with mobile devices from various brands, including Xiaomi.
💡
The stability of the wireless connection depends on the distance to the router and the presence of physical obstacles (walls, furniture).
Broadcast from specific applications (YouTube, Netflix)
The content streaming from apps deserves special attention, and YouTube, Netflix or Kinopoisk have a built-in "Translate" button, which works differently than a full screen broadcast.
The phone is just a remote control, and it sends a video link to the TV, which downloads the stream itself, which reduces the load on the smartphone and saves battery life.
The quality in this mode is usually higher, because the TV directly accesses the video hosting server, so you can turn off the phone screen and the video will continue to play.
