Why Xiaomi’s Wireless Display Doesn’t Work: A Complete Troubleshooting Guide

You try to stream a Xiaomi smartphone screen to a TV or monitor via the Mi Wireless Display, but instead of a picture, you see a failed connection error, a black screen or permanent connection breaks? The problem is familiar to many owners of Redmi, POCO and Mi devices — especially after MIUI updates or when working with TVs other than Xiaomi. 80% of the time the malfunction is not due to hardware breakdowns, but to software conflicts that can be fixed on their own.

In this article, we’ll look at all the possible reasons why your Xiaomi wireless display doesn’t work, from simple setup errors to hidden firmware bugs. You’ll learn how Miracast, Mi Wireless Display and AirPlay work on different models, why the broadcasts stop or fail in 10 seconds, and what to do if the TV just can’t see your smartphone. And for Xiaomi TV owners, we’ve prepared a separate section with unique solutions — their problems are often different from the standard ones.

Warning: If you use custom firmware (e.g. Pixel Experience or LineageOS), some of the wireless display functions may be disabled at the kernel level, requiring manual editing of system files, as you will find instructions for such cases at the end of the article.

1.Basic conditions check: why the TV can't see Xiaomi

Before digging deep into the settings, make sure the minimum requirements for a wireless display are met, and errors occur in 30% of service center calls at this stage — all resolved in 2 minutes.

• 📶 Both networks on the same frequency: both the smartphone and the TV must be connected to the same 5 GHz Wi-Fi network (2.4 GHz does not support Miracast due to high latency), except for live Wi-Fi Direct, but it does not work on all models.
• 🔄 Miracast Mode is enabled: on Samsung, LG or Sony TVs, you need to manually activate Screen Mirroring or Wi-Fi Display in the network settings.
• 📱 MIUI not lower than 12: on older versions (MIUI 10-11), the wireless display malfunctions. Update the firmware through Settings → About Phone → System Update.
• 🔌 Energy Saving Disabled: Battery Mode → Energy Saving Blocks Background Activity of Mi Wireless Display. Add the app to the exceptions.

A critical mistake many users make is trying to connect to a TV via mobile internet (4G/5G) instead of Wi-Fi. The wireless display on Xiaomi only works on the local network - even if you have an unlimited tariff.

⚠️ Warning: On Xiaomi TV A2 and ES2022 TVs, the Mi Wireless Display feature is disabled by default to save power. To activate it, go to Settings → Connections → Wireless Display → Additional → Standby Mode and select Always On.

2.The Difference Between Miracast, Mi Wireless Display and AirPlay: Which to Choose

Many users confuse these technologies and then wonder why the screen is slowing down or the sound is late, and let’s see how they differ and what protocol is best to use on your Xiaomi:

If you have a Xiaomi 11/12/13 series or Redmi Note 10 Pro+, use the Mi Wireless Display, which is optimized for these models and gives minimal delays. For older smartphones (for example, Redmi 9 or Mi A3) you will have to settle for Miracast, but be prepared for artifacts when watching videos.

Xiaomi TV P1/E2 is best suited for Mi Wireless Display + Game Mode (included in screen settings) which reduces latency to 30ms – critical for gaming via Xbox Cloud Gaming or GeForce NOW.

💡

Mi Wireless Display supports HDR10 only on smartphones with Snapdragon 8 Series processor (865/870/888/8 Gen 1+). On devices with MediaTek (Dimensity), color reproduction is limited to SDR.

3. Step-by-step setting up Mi Wireless Display on Xiaomi smartphone

If the TV supports Mi Wireless Display but the smartphone doesn’t see it, follow this instruction. Note: on some models (e.g. POCO F3), the menu item may be called Cast or Smart View.

1. Open Settings → Connections and Sharing → Wireless Display (on MIUI 14, the path may differ: Settings → Screen → Wireless Display).
2. Activate the Wireless Display slider (if it’s gray, check your 5GHz Wi-Fi connection).
3. From the list of available devices, select your TV. If not: 🔄 Reboot your router and smartphone. 📱 On your smartphone, turn off VPN (e.g., 1.1.1.1 or AdGuard, they block local traffic). 🖥️ On your TV, update your firmware through Settings → Software Update.

After connecting, select the broadcast mode:

• Duplicate the screen – mirrors the display of the smartphone (suitable for presentations).
• Use as a second screen – expands the desktop (useful for multitasking).

If the screen is connected, but the image is slowing down:

• 🎮 Enable Game Mode in the TV settings (reduces buffering).
• 📶 Switch the router to the 36-48 channel in the Wi-Fi settings (less loaded).
• 🔋 Connect your smartphone to charging – at low battery levels MIUI limits performance.

4. Typical errors and their solutions

We will analyze the most common errors when working with a wireless display on Xiaomi, which users often confuse with breakdowns:

Error 1: "I failed to connect to the device"

Reasons:

• 🔒 Block MAC- addresses on the router (often on Keenetic or ASUS RT). Solution: add MAC- addresses to the whitelist.
• 📡 Weak Wi-Fi signal. Check signal strength in Settings → Wi-Fi – if less than 70%, move the router closer.
• 🛠️ Failure in com.miui.miracast. Solution: Clear the app cache through Settings → Applications → Application Management → System → Wireless Display → Storage → Clear the cache.

Error 2: The screen is plugged in, but shuts down after 10 seconds

This is a typical problem on the Redmi Note 9/10 due to a bug in MIUI 12.5.

• 🔄 Reverse to MIUI 12.0.9 (stable version) via fastboot.
• 📱 Turn on Developer Mode and activate Do not turn off the screen while charging.
• 🔌 Connect your smartphone to charge — some firmware broadcasts are cut off when the discharge is below 80%.

Error 3: No sound when broadcasting

Most commonly found on LG or Philips TVs.

• 🔊 In the broadcast settings on the smartphone, is the item "Transmit sound" selected?
• 🎵 On the TV in Sound Settings → Output set HDMI ARC or Optical.
• 📱 Bluetooth headphones are disabled on the smartphone (they can intercept the audio stream).

💡

If the sound is late, try the settings of the TV to turn on Lipsinc (Audio Sync) and manually select the delay in the range of 50-150 ms.

Error 4: Black screen when connected

The conflict of permissions is to blame.

• 📺 On your TV, manually set the 1920×1080@60Hz resolution (even if it supports 4K).
• 📱 On your smartphone, in the broadcast settings, select Optimize for Video instead of Optimize for Games.
• 🔧 If you use a MHL- adapter, turn it off — it can block wireless broadcasting.

⚠️ Warning: On Xiaomi 12T Pro and 13 Ultra smartphones, the black screen may be caused by a bug in the qti.display.composer driver.The solution is to roll back to the firmware V14.0.4.0.TLBCNXM or wait for a patch.

5. Features of working with Xiaomi TV (A2, P1, E2, S Pro)

Xiaomi TVs have unique wireless display issues that other brands don't.

• 📺 Xiaomi TV A2 (2023): By default, it blocks Android 13+ smartphones due to a bug in PatchWall.
• 🎮 Xiaomi TV P1: When streaming games over Xbox Cloud or GeForce NOW, you need to manually enable Game Mode in the HDMI- port settings (even if the connection is wireless!).
• 🔊 Xiaomi TV ES2022: The broadcast sound is only transmitted via HDMI ARC. If the Bluetooth speakers are connected, the sound will be duplicated with a delay.
• 📱 All models: If the smartphone connects but the screen flashes, turn off the TV's brightness settings (Settings → Screen → Brightness → Autosetting).

For owners of Xiaomi TV Stick or Mi Box S:

These devices only support Miracast, but with limitations:

• Maximum resolution is 1920×1080@30fps.
• The sound is only transmitted in Stereo format (not 5.1).
• When connecting a Xiaomi smartphone to the Mi Box, you need to manually select the Miracast protocol in the broadcast settings (by default, Mi Wireless Display is not compatible).
