Wireless display on Xiaomi: how it works and how to configure without delay

Wirelessly transferring images from a Xiaomi smartphone or tablet to a TV, monitor or projector has become an integral part of the modern multimedia experience. Technology allows you to stream movies, games, presentations and even duplicate a desktop without a single wire โ€” but how exactly does this work under the hood? In this article, we will analyze all the available protocols (Miracast, AirPlay, Wi-Fi Direct), their differences, limitations and step-by-step instructions for Xiaomi devices based on MIUI and HyperOS.

You'll learn why audio delays sometimes occur, how to choose the optimal resolution for broadcasting, and what to do if devices can't see each other. And we've also tested the real performance of a wireless display on Xiaomi 14 flagships and the budget Redmi Note 12 -- the results may surprise you. Let's start with the basics: what technologies underlie the feature, and how they differ.

1. Wireless broadcast technologies: Miracast vs AirPlay vs Wi-Fi Direct

Xiaomi devices have three basic protocols for airborne screen transmission, each with unique features, pros and cons.

  • ๐Ÿ“ถ Miracast is a Wi-Fi Alliance standard that works over Wi-Fi Direct. It doesn't require a router, it creates a direct network between devices. It's supported by all Android TVs. TV and most of the Xiaomi smartphones (starting with the MIUI 8).
  • ๐ŸŽ AirPlay is a proprietary protocol from Apple, but Xiaomi has added its support to some models (for example, Xiaomi). TV A2 mi TV Q2). Works only with Apple devices (iPhone, Mac) or through third-party apps on Android.
  • ๐Ÿ”„ Wi-Fi Direct is the underlying technology behind Miracast, which allows devices to connect directly, but without a standardized screen broadcast protocol, and is used to transfer files or connect peripherals.

The key difference is that Miracast and AirPlay are optimized for multimedia (low latency, audio synchronization), whereas Wi-Fi Direct is just a pipe for data transfer. For example, when playing Call of Duty Mobile via Miracast, the delay will be ~50 ms, and through Wi-Fi Direct without optimization - up to 200 ms.

2.How to turn on the wireless display on the Xiaomi smartphone: step-by-step instructions

The activation algorithm depends on the firmware version (MIUI or HyperOS) and the device model. Below is a universal guide for most smartphones:

  1. Open Settings โ†’ Connection and Sharing โ†’ Wireless display (in HyperOS, the path may differ: Settings โ†’ Screen โ†’ Wireless monitor).
  2. Activate the Wireless Display slider (on some models - Miracast).
  3. From the list of available devices, select your target TV or monitor. If you don't have one, make sure that the TV is on Screen Mirroring (on Xiaomi TV, this is Settings โ†’ Network โ†’ Wireless Display).
  4. Confirm the connection on both devices. On the screen of the smartphone will appear a notification of the successful broadcast.

On Xiaomi Pad 6 and other tablets, the path may be different: Settings โ†’ Display โ†’ Wireless monitor. If you donโ€™t have an option, check the firmware update (the minimum version for Miracast is MIUI 10).

Make sure both devices are connected to the same Wi-Fi network (for AirPlay)

Turn off VPN and energy saving modes

Close the background applications (especially messengers)

Check that the screen is on "Screen Mirroring"-->

โš ๏ธ Note: On smartphones with HyperOS (such as Xiaomi 14), the wireless display feature may conflict with Game Turbo.

3. Optimization of broadcast quality: resolution, FPS and bitrate

By default, Xiaomi limits the broadcast resolution to 1080p@30Hz to reduce the load on the processor and battery. However, on flagship models (for example, Xiaomi 13 Pro) you can manually increase the parameters:

  • ๐ŸŽฎ For games: Choose 720p@60 Hz - this will reduce the delay to ~40 MS (against) 80 pr 1080p).
  • ๐ŸŽฌ For the movies: Optimal 1080p@24 Hz (meets the movie standard) with included HDR (if maintained).
  • ๐Ÿ“Š For presentations: Enough 1080p@30 Hz โ€“ the clarity of the text will be acceptable.

To change the settings:

  1. Connect to the wireless display.
  2. Slap on the broadcast notification in the curtain.
  3. Select Settings โ†’ Image quality.
  4. Set the required resolution and frame rate.

Critical detail: On the Redmi Note 11 and older, when selecting 4K, the broadcast automatically drops to 30Hz, even if you specify 60Hz - this is the limitation of the Snapdragon 680 chipset.

๐Ÿ’ก

If the image โ€œbreaksโ€ during the broadcast, try to reduce the bitrate manually: in the developer settings (Settings โ†’ About Phone โ†’ MIUI version โ€“ tap 7 times) turn on the option to Limit Miracast bitrate and set the value of 10 Mbit / s.

4. Common Problems and Their Solutions

Even on top-end Xiaomi devices, users are faced with typical wireless broadcast errors, and here are the most common ones and fixes:

Problem.Reason.Decision
Devices can't see each other.Wi-Fi Channel ConflictSwitch the router to channel 6 or 11 (2.4 GHz)
Sound delay ~1 sUnsynchronized audio codecsIn the TV settings, select PCM instead of Dolby.
Black screen when connectedDRM Limitations (Netflix, Disney+)Use Google Cast instead of Miracast
Broadcast cuts offWeak Wi-Fi signalReduce the distance to 3 meters or use 5 GHz

If the problem persists, try resetting the network settings on your smartphone: Settings โ†’ SIM-maps and mobile networks โ†’ Reset network settings. on Xiaomi TV Similar option is in the settings โ†’ Network โ†’ Additionally. โ†’ Resetting the network.

โš ๏ธ Note: When broadcasting content from DRM-Protection (e.g., Kion or Okko movies) through Miracast may cause artifacts or completely shut down the sound. In this case, use Google Cast (built into streaming apps).

Comparison with wired solutions: pros and cons

Wireless streaming is convenient, but inferior to wired connections (such as USB-C to HDMI) in key parameters.

  • โšก Delay: Wire โ€“ 5-10 ms, Miracast โ€“ 30โ€“80 ms, AirPlay โ€“ 20โ€“50 ms.
  • ๐ŸŽจ Quality: The wire supports 4K@120 Hz. HDR10+, wireless protocols โ€“ maximum 4K@60 Hz (more often) 30 Hz).
  • ๐Ÿ”‹ Power consumption: Wireless transmission drains the battery by 15-20% per hour (versus 5% for wired connection).
  • ๐Ÿ”Œ Universality: Wire requires adapters, wireless display works out of the box with any compatible TV.

For gamers and professional work (video editing, graphic design), wired connectivity remains a priority, but for everyday tasks โ€” watching movies, presentations or streams โ€” Miracast on Xiaomi does a great job.

How to check for real broadcast delay?
Download the Game Mode Latency Test app from Google Play. Connect your smartphone to your TV via Miracast, run the test, and take a video of your TV screen to another camera. Compare your smartphone and TV reaction times with a frame analysis software (like VirtualDub), the difference being a delay.

6. Alternative ways to stream the screen on Xiaomi

If the built-in Miracast is not satisfied with quality or stability, consider alternatives:

  • ๐Ÿ“ฑ Google Cast: Built into YouTube, Netflix and other apps. Runs through a router, supports 4K HDR. The downside is that it doesnโ€™t duplicate the entire screen, only content from supported apps.
  • ๐Ÿ–ฅ๏ธ TeamViewer QuickSupport: Allows you to remotely control your smartphone from a PC or other device, suitable for technical support, but not for multimedia (latency) ~300 ms).
  • ๐Ÿ”— ApowerMirror: Third-party app with support 1080p@60 Hz and screen recording. Requires the server part to be installed on a PC or TV.
  • ๐ŸŽฎ Steam Link: Optimized for streaming PC games to your smartphone or TV. ~20 ms on the local network.

Xiaomi TV owners have an exclusive feature called MIUI+, which allows you to not only broadcast the screen, but also control the smartphone from the TV remote, as well as synchronize the clipboard.

  1. On your smartphone: Settings โ†’ Connection and Sharing โ†’ MIUI+.
  2. On TV: Settings โ†’ Accounts and Security โ†’ MIUI+
  3. Scan the TV scanner. QR-smartphone-code.

๐Ÿ’ก

MIUI+ only works between Xiaomi devices and requires a Mi Account. the feature is not available on smartphones with firmware from third-party developers (for example, Pixel Experience).

7.Security of wireless broadcasting: what you need to know

Airborne screen transmission carries the risk of interception or unauthorized connection.

  • ๐Ÿ”’ Turn off automatic connection: In Miracast settings, deactivate the option of Autoconnect to known devices.
  • ๐Ÿ›ก๏ธ Use it. WPA3: If the broadcast is via the router, make sure the network is secure. WPA3-Personal (setting up in the admin panel of the router).
  • ๐Ÿ‘๏ธ Check Connected Devices: On Xiaomi TV The list of active connections can be seen in Settings โ†’ Wireless networks โ†’ Miracast devices.
  • ๐Ÿ”„ Update firmware: Vulnerabilities in Miracast (e.g, CVE-2021-0322) Closed in monthly security patches.

On Xiaomi corporate devices (e.g., Xiaomi Mi 11 Lite NE with Android Enterprise), the administrator can completely block Miracast through DevicePolicyManager policies. To check the restrictions, enter the command in the engineering menu:

adb shell dumpsys device_policy

โš ๏ธ Note: When connecting to public displays (such as hotels or airports), never share sensitive information โ€“ Miracast traffic on open networks can be intercepted using Wireshark or specialized utilities like Miracast Sniffer.

FAQ: Frequent questions about wireless display on Xiaomi

๐Ÿ” Why there is no sound when broadcasting via Miracast?
The problem is typical for devices with non-standard audio codecs. Solutions: On TV, switch the audio output to PCM (in audio settings). On your smartphone, turn off Bluetooth audio (may conflict with Miracast). Update the TV and smartphone firmware - MIUI 14 fixes bugs with the transmission of sound over LDAC. If the sound appears with a delay, try to reduce the bitrate of audio in the developer settings (Disable absolute volume).
๐Ÿ“บ Can I broadcast the screen on Xiaomi? TV past 2018?
Yes, but with limitations: 2016-2018 models (e.g. Mi TV 4A) only support Miracast without HDR and with a maximum resolution of 1080p@30Hz. For stable operation, update your TV firmware to the latest version via Settings โ†’ Software Update. If TV does not find your smartphone, use Google Cast through apps (e.g. YouTube). On Mi TV 3S (2016), Miracast only works with Android 8.0 and below smartphones.
๐ŸŽฎ How to reduce latency when playing through a wireless display?
Minimizing the lag will help: Switch to 720p@60Hz (in broadcast settings). Using a router with Wi-Fi 6 support (for example, Xiaomi AX6000) and connecting TV via Ethernet cable. Activating Game Mode on TV (Settings โ†’ Picture โ†’ Image Mode). Disabling background processes on your smartphone through Settings โ†’ Applications โ†’ Autostart. On POCO F5 with Snapdragon 7+ Gen 2, the delay in Call of Duty Mobile via Miracast is ~45 ms (vs versus ~15 ms over cable).
๐Ÿ”‹ Why a Wireless Display Is Draining Your Battery Quickly?
The screen broadcast activates: Wi-Fi Direct module (consumption ~1.2 W); Video encoder (H.264 or H.265, GPU load up to 30%); Constant screen activity (backlights do not turn off); To save charge: Reduce screen brightness to 50%; Connect your smartphone to charging (preferably with Quick Charge 3.0+ support); Use Battery mode in the broadcast settings (limits FPS to 30).
๐Ÿ–ฅ๏ธ Can a wireless display be used to duplicate the screen on a PC?
Yes, but not through Miracast. Options: Miracast on Windows: Enable Projection on this computer in Settings โ†’ System โ†’ Projection on this PC. Xiaomi smartphone will find the PC as a wireless display. Party of the application: ApowerMirror, LetsView or Scrcpy (the latter requires ADB). Through Mi Share: On a PC, install Mi PC Suite, on a smartphone activate Mi Share in the curtain. The function allows you to broadcast files, but not the screen. Linux will require you to configure gstreamer or use Wayland-compatible utilities (for example, wderfre).
