Broadcasting a screen from Xiaomi's phone to the big screen is not just a handy feature, it's a real godsend for gamers, movie lovers and people who often give presentations. But how exactly does this technology work? Why does one model have two-click wireless broadcasts and others require a tambourine dance? And most importantly, how do you avoid delays, communication breaks and sound problems?
In this article, we will analyze all the ways of broadcasting on Xiaomi, Redmi and smartphones. POCO โ From standard Miracast to hidden features MIUI, You'll learn what protocols your devices support, how to get around manufacturer restrictions, what to do if the broadcast is constantly interrupted, and also compare the real latency when using Wi-Fi 5 vs Wi-Fi 6 in tests of 2026.
1. What broadcast technologies support Xiaomi smartphones
Xiaomi smartphones use several protocols to transfer images to external screens. The choice of technology depends on the model of the phone, version of the device. MIUI And the target device (TV, monitor, projector) are the basic standards:
- ๐ก Miracast is a wireless standard built into most modern TVs, works without the Internet, but requires support on both sides.
- ๐ฏ Google Cast (Chromecast) is a protocol from Google that uses a Wi-Fi network. TV and Chromecast devices. MIUI It can be called a broadcast or a Cast.
- ๐ Wi-Fi Direct is a direct connection between a phone and a TV without a router, often used in older Xiaomi models (e.g. Redmi Note 4).
- โก HDMI via adapter - wired connection through USB-C โ HDMI or micro-USB โ HDMI (It's very late, but it requires you to buy an adapter.
Important: not all TVs support Miracast, for example, many Samsung models require third-party software to be installed until 2019 (e.g., Miracast Receiver from the app store). TV (For example, Xiaomi Mi TV, Sony Bravia usually works with Google Cast out of the box".
Another nuance - version MIUI. In the firmware older MIUI The 12th stream menu is hidden deep in the settings, and in newer versions (like HyperOS) it is displayed on the Quick Settings panel.
2. Where to find the broadcast settings in MIUI hyperos
The location of the feature depends on the firmware version.In recent updates, Xiaomi has made it easier to access the broadcast, but in older versions MIUI (for example, MIUI 11) the path can take up to 5 clicks. Here are the current instructions:
For MIUI 12โ14 and HyperOS (2020โ2026)

- Find the Broadcast icon (or Cast, Wireless Display) and if it's not there, tap it on your pencil and add it manually.
- Select the target device from the list.
For MIUI 10โ11 (2018โ2019)
The path is harder:
- Go to Settings. โ Connections and sharing โ Broadcasting.
- Activate the Wireless Display slider.
- Find your TV or projector in the list.
If the broadcast icon is not available even after editing the notification bar, check:

If your Xiaomi can't find your TV, try turning on Miracast mode manually. On the Samsung remote, this is the Source button. โ Screen Mirroring, on LG โ Input โ Miracast.
3. Which Xiaomi models don't support streaming (and why)
Not all Xiaomi smartphones can broadcast the screen over the air.
| Model | Reason for the lack of broadcasting | Alternative means |
|---|---|---|
| Redmi 4A/5A, Mi A1/A2 | Weak processor (Snapdragon) 425/435) and outdated MIUI 9โ10 without Miracast support. | Connection via Micro-USB โ HDMI adapter (delay) ~50 ms). |
| POCO F1 (on MIUI 10) | The firmware does not include drivers for Wi-Fi Direct due to optimizations for games. | Update to MIUI 12+ Or use Google Cast through YouTube/Netflix. |

| Delay over 200 ms | Weak Wi-Fi signal or overloaded router | Switch to 5 GHz, disconnect other devices from the network. |
| The broadcast stops every 5 minutes. | Energy saving phone turns off Wi-Fi | Add the Broadcast app to battery exclusions (Settings) โ Battery โ Optimization). |
If the phone gets hot after the broadcast, and the battery goes down. 30 Minutes are normal for models with Snapdragon processors 7xx/8xx. To reduce the load, reduce the resolution of the broadcast in the settings (720p instead 1080p).
