1. Wireless streaming on Miracast: a universal method for all Xiaomi
Miracast is a wireless screen transmission standard that supports all Xiaomi smartphones since the Redmi 4X (2017) and TVs with HDMI 1.4+. The main advantage of the method is that you do not need to connect to a single Wi-Fi network: the phone and TV create direct communication, which reduces latency to 50-100 ms (critical for games).
To activate Miracast on your smartphone:
- Open Settings โ Connection and Sharing โ Screen Transfer.
- Select the Wireless Display option (on some firmware - Miracast).
- Turn on device search. The TV should appear in the list (for example, as Samsung TV (Miracast) or LG TV (Screen Share)).
- Confirm the connection on both devices.
On the TV, pre-activate the signal reception mode:
- ๐บ Samsung: Source โ Screen Mirroring (or Smart View).
- ๐บ LG: Settings โ Network โ Miracast/Screen Share.
- ๐บ Xiaomi TV: Settings โ Connection โ Wireless display.
- ๐บ Sony Bravia: Settings โ Network โ Screen Mirroring.
โ ๏ธ Note: If the TV is not displayed in the list of devices, check: Does your model support Miracast TV (list of incompatible models - in the table below). USB (Is the TV firmware updated (Samsung needs an update to support Miracast until 2018).

2. Google Cast (Chromecast): for streaming video and music
If you need to stream content from apps (YouTube, Netflix, Wavve) rather than duplicate the entire screen, use Google Cast. This protocol is optimized for media files: it supports 4K HDR and Dolby Atmos, whereas Miracast is often limited to 1080p resolution.
Instructions for Xiaomi:
- Make sure your phone and TV are connected to the same Wi-Fi network (unlike Miracast, this is a must!).
- Open an app that supports Cast (like YouTube).
- Slip on the broadcast icon (๐ก) and select your TV from the list.
- To duplicate the entire screen: open Settings โ Connect โ Screen Transfer โ Google Cast.
If the Cast icon is not active:
- ๐ Restart your router (sometimes) DHCP-The server does not provide the correct IP-multicast).
- ๐ฑ Update the app (for example, Netflix only added Cast support from version 7.0).
- ๐ ๏ธ On the TV, turn on the Permit Cast option (on the LG It's the settings. โ General. โ Devices โ TV Cast).
โ ๏ธ Attention: On Xiaomi TVs TV Google Cast may not be supported in 2020, and you may need an external adapter like Xiaomi Mi. TV Stick (cost) ~2000โฝ).

- ๐ adapter USB-C โ HDMI (We recommend the original Xiaomi USB-C to HDMI Adapter or Anker Certified).
- ๐บ Cable HDMI 2.0 or later (for 4K necessarily!).
- โก Power supply for adapter (some models require charging connection).
Step-by-step:
- Connect the adapter to the USB-C port of the smartphone.
- Connect the adapter to the TV with an HDMI cable.
- On the TV, select the signal source (HDMI 1/2).
- On the phone in the Settings menu โ Screen โ Screen โ Screen resolution set 1080p or 4K (if TV supports).

|---|---|---|---|
| Xiaomi 13/13 Pro | 4K@60Hz | Yes (5V/1A) | Supports HDR10+ |
| Redmi Note 12 Pro+ | 4K@30Hz | No. | Max 1080p@60Hz without external power supply |
| POCO F5 | 1440p@60Hz | Yes (9V/2A) | Requires an adapter with DisplayPort 1.4 chip |

If the image on the TV is cropped at the edges, on the phone turn on the No stretch mode in the settings HDMI-Adapter (usually available in the Developer Menu).
4.Wi-Fi Direct: Miracast alternative for older TVs
Wi-Fi Direct is a technology that allows devices to connect directly without a router. It's useful if your TV doesn't support Miracast, but there's a Screen Mirroring feature. This is how many 2016-2019 Sony models connect, for example.
How to set up Wi-Fi Direct on Xiaomi:
- On your TV, activate Wi-Fi Direct (on Sony: Settings โ Network โ Wi-Fi Direct).
- On the phone, open Settings โ Wi-Fi โ Additional โ Wi-Fi Direct.
- Select the TV from the list and confirm the connection (the password is usually displayed on the TV screen).
- Run the broadcast through Settings โ Screen Transfer โ Wi-Fi Direct.
Limitations of the method:
- โ ๏ธ Maximum authorization โ 1080p@30Hz (no support 4K).
- โ ๏ธ Delay up to 200 ms (not suitable for gaming).
- โ ๏ธ On some TVs. LG You need to turn off Bluetooth before connecting.
Why is Wi-Fi Direct slower than Miracast?
5. Connection via DLNA: for Photos, Videos and Music
If you donโt need to duplicate the screen, but only broadcast media files (photos, videos, music) โ use DLNA. This protocol supports all Xiaomi smartphones and most TVs. The main advantage is that there is no binding to specific applications (as in Google Cast), you can transfer any files from the gallery.
Instructions:
- On your TV, turn on DLNA (on Samsung: Settings โ General โ External Devices โ DLNA Devices).
- On your phone, install the Mi Home or BubbleUPnP app (for advanced features).
- In the application, select the file and tap Translate โ specify the TV.
Tips for stable work:
- ๐ Transmit the file format MP4 (H.264) or MKV โ They're supported by all TV.
- ๐ If the video slows down, reduce the bitrate in the application settings (optimal: 10-15 Mbit/s).
- ๐ For 4K-Files use a wired connection or router with Wi-Fi 6.
๐ก
DLNA doesn't duplicate your phone's screen, it only transfers media files. Use Miracast or HDMI to mirror your screen.
6. Problem Solving: Why the Connection Is Not Working
