Why is it not always easy to โthrowโ the Xiaomi screen on the TV?
You want to show pictures from your vacation on the big screen, run a mobile game on your TV or stream a movie with Xiaomi โ but you run into a problem: the phone does not see TV, the picture is slowing down or the connection is constantly breaking. The reason often lies in incompatible wireless protocols, outdated TV drivers or incorrect smartphone settings. For example, low-end Redmi models (for example, Redmi Note 12) may not support Miracast on old Samsung TVs 2018, and flagships like Xiaomi 14 Ultra require manual resolution settings when connecting via HDMI.
In this article, we will look at all the current ways of screen duplication, from wireless (Wi-Fi Direct, Miracast) to wired (USB-C/HDMI, adapters), and also reveal hidden MIUI settings that the manufacturer does not advertise. For example, why some LG TVs connect through Screen Mirroring sound only through the phone, and how to fix it.
1. Wireless connection via Miracast (Screen Mirroring)
The most versatile way for modern TVs (2019 and later) is Miracast technology, built into MIUI called Wireless Display or Screen Mirroring. It works without a router, directly linking the phone and TV over Wi-Fi Direct. The main condition is that both devices must support the Miracast standard (check in the specifications of your model).
How to turn on:
- On TV: go to Settings โ Network โ Screen Mirroring (on Samsung it can be Smart View, on LG โ Miracast).
- On Xiaomi: Open Settings โ Connection and Sharing โ Wireless Display.
- In the list of available devices, select the name of your TV.
โ ๏ธ Attention: On phones POCO (for example, POCO X5 Pro) path may be different: Settings โ Additionally. โ Wireless display. If you don't have an option, upgrade. MIUI The last version is in the old firmware (below). MIUI 12) Miracast is often offline.
Both devices are connected to the same Wi-Fi network (if required)|The TV supports Miracast (see instructions)|The phone has enabled the โVisible for allโ mode in the wireless display settings|Disabled. VPN and energy-saving regimes-->
2. Wired connection via USB-C โ HDMI (for 4K and games)
If you want minimal picture lag (relevant for gaming or watching video in 4K@60fps), use a wired USB-C โ HDMI adapter.This method works on all Xiaomi with a USB Type-C port (starting with the Redmi Note 10 and later), but requires:
- ๐ Active adapter (passive cables do not transmit video!) We recommend the official Xiaomi USB-C to HDMI Certified Adapters from Anker.
- ๐บ Port TVs HDMI 2.0 (for) 4K) or HDMI 1.4 (for Full) HD).
- โก Power supply for the phone (adapter consumes a lot of power).
Step-by-step:
- Connect the adapter to the USB-C port of the phone.
- Connect the adapter to the TV through HDMI-cable.
- On the TV, select the appropriate signal source (HDMI 1/2/3).
- On the phone in the notification bar will appear the option Transfer to HDMI โ click on it to configure the resolution.

If the image doesnโt show up, try restarting the phone with the adapter connected. Some Xiaomi models (such as the Mi 11 Lite) require manually enabling USB Debugging in the developer settings.
โ ๏ธ Note: When connecting through HDMI The phone may turn off the sound. To get it back, go to Settings. โ Sound. โ Sound output and select HDMI.
| Xiaomi model | Supported HDMI resolution | Max. Frequency. | Is the adapter power required? |
|---|---|---|---|
| Xiaomi 13/14 Pro | 4K (3840ร2160) | 60 Hz | Yes (recommended) |
| Redmi Note 12 Pro+ | 2K (2560ร1440) | 60 Hz | Yes. |
| POCO F5 | Full HD (1920ร1080) | 60 Hz | No. |
| Xiaomi Pad 6 | 4K (3840ร2160) | 30 Hz | Yes. |
3. Wi-Fi connection (DLNA and Google Cast)
If your TV supports Google Cast (built into Android TV, Sony Bravia, Philips with Android TV) or DLNA (mostly Samsung, LG), you can only stream multimedia (video, photos, music), but not the entire screen.
For Google Cast:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- Open the video to YouTube, Google Photos or MIUI Gallery.
- Click on the broadcast icon (๐ก) and choose your TV.
For DLNA:
- ๐ฑ On your phone: install the Mi Home or BubbleUPnP app.
- ๐บ On TV: Turn on the mode DLNA network-setting.
- ๐ In the application, select files for broadcast and send them to TV.

โ ๏ธ Note: When broadcasting through DLNA Sound can be up to 2 seconds late, and that's a feature of the protocol, which is that you can't fix it, but you can reduce it using a router that supports Wi-Fi 6.
4.Using a USB-C adapter โ USB-A (MHL)
For older TVs (until 2018) or HDMI-free models, you can use MHL (Mobile High-Definition Link) technology, which allows you to transfer video over a USB-A port of the TV, but requires:
- ๐ Special adapter USB-C โ MHL/HDMI (for example, Xiaomi MHL Adapter).
- ๐บ Supported TV MHL (check in the instructions).
- โก Power supply for the adapter (usually included).
How to connect:
- Connect the adapter to your phone and TV.
- Connect the power supply to the adapter.
- On the TV, select the USB or MHL source.
Why is MHL going back in time?
โ ๏ธ Note: On Xiaomi phones with Snapdragon 8 Gen 2 processor (e.g. Xiaomi) 13T Pro) MHL Not supported due to lack of hardware compatibility.
5. Alternative ways: Chromecast and Smart TV-applications
If built-in methods donโt work, use external devices or applications:
Google Chromecast:
- ๐ฑ Buy a Chromecast device (from 3,000) โฝ) And plug him into the TV.
- ๐ In your phone, install Google Home and follow the setup instructions.
- ๐ฌ To broadcast the screen, use the option Broadcast screen in Google Home.
Applications for Smart TV:
- ๐บ Install ApowerMirror or TeamViewer QuickSupport on your TV.
- ๐ฑ On the phone, launch the corresponding application and connect to the TV by code.
- โก Advantage: Work even on older Android TVs TV 5.0+.

Chromecast is the only way to bring Xiaomiโs screen to your TV without Miracast or HDMI built-in support.Suitable for models like Redmi 9A, where there is no Wireless display in the settings.
6. Solving typical connection problems
If the screen is not duplicated or the broadcast is interrupted, check:
| Problem. | Possible cause | Decision |
|---|---|---|
| The phone can't see the TV. | Wi-Fi Direct is disabled on TV | Turn Screen Mirroring on in your TV settings |
| The picture slows down. | Weak Wi-Fi signal | Connect to 5 GHz network or use HDMI |
| No sound. | Wrong sound output | In the phone settings, select Sound Output โ HDMI |
| The screen flashes. | Permit mismatch | In Miracast settings, set 1080p instead of 4K |
โ ๏ธ Note: On Xiaomi phones with MIUI 14+ when connected HDMI It's a firmware bug, a temporary solution: turn off. HDCP in the developer settings (Settings) โ The phone. โ Version. MIUI โ 5 taps).
