eShare on Android TV: complete guide for setting up wireless screen mirroring

Wireless screen sharing from a phone or laptop to Android TV via technology eShare (or Miracast) opens up new opportunities for viewing content, presentations and games on the big screen. However, many users encounter problems when connecting for the first time: the TV does not find the device, the image is slow, or the connection is constantly disconnected. In this article we will examine step-by-step setup of eShare popular models Android TV (including Xiaomi Mi TV, Sony Bravia, Nvidia Shield), and also tell you how to eliminate common errors and optimize operation.

It is important to understand that eShare is the proprietary name of the technology Miracast from the company Realtek, which is used in most modern Android TVdevices. It allows you to broadcast the screen without a router (in Wi-Fi Directmode), but requires support from both devices. If your smartphone or PC is not equipped with a module Miracast, you will need additional software or an adapter.

Before you start setting up, check:

• 📺 The TV supports Miracast/eShare (usually indicated in the characteristics or menu Settings → Wireless networks).
• 📱 The source device (smartphone, laptop) is compatible with the technology. On Android this can be checked in the settings Screen → Wireless transmission.
• 🔄 Both devices are updated to the latest firmware versions (especially important for Xiaomi TV i Sony Android TV).

1. Preparing Android TV for connecting via eShare

Before the first connection, you must activate function wireless display in the TV settings. The process may vary slightly depending on the model, but the general logic remains the same.

On most Android TV the path looks like this:

1. Open Settings (gear in the upper right corner of the main screen).
2. Go to the section Devices and networks (or Network and Internet on some models).
3. Select Wireless display, Miracast or eShare (may be called Xiaomi TV may be called Screen Mirroring).
4. Activate slider Enable or click Start searching for devices.

If there is no item in the menu eShare, try alternative ways:

• 🔍 On Sony Bravia: Settings → Network services → Miracast.
• 🔍 On Nvidia Shield: Settings → Display and sound → Wireless display.
• 🔍 On Philips Android TV: Settings → Wireless networks → Wi-Fi Direct.

After activation, the TV will begin scanning for available devices. At this stage, it is important that:

• 📶 The TV and the source device are no more than 5 meters from each other.
• 🔋 The charge level of the smartphone/laptop is not lower 30% (if the battery is low, the connection may be interrupted).
• 🚫 Neither device is connected to a VPN or proxy (this may block it Wi-Fi Direct).

2. Setting up eShare on a smartphone or PC

Now let's move on to the device from which the screen will be broadcast. Instructions for Android, Windows and macOS are different, so select the desired option.

For Android smartphones (Samsung, Xiaomi, Google Pixel, etc.)

On most modern smartphones, the wireless screen sharing function is built into the system:

1. Open Settings → Connections (or Connection devices).
2. Select Wireless display, Smart View (on Samsung) or Transmit (on Xiaomi).
3. Turn on the function and wait until the smartphone finds yours Android TV.
4. Click on the name of the TV in the list and confirm the connection.

On some firmware (for example, MIUI on Xiaomi) You may need to:

• 🔄 Enable Developer mode and activate Debugging via Wi-Fi (press 7 times). Settings → About phone → MIUI version press 7 times).
• 📱 Install the application Miracast from Google Playif the built-in function is missing.

For Windows 10/11

On a PC with Windows setting is done through Screen options:

1. Click Win + K (or open Settings → System → Display → Connect to wireless display).
2. Select your Android TV from the list of available devices.
3. Confirm the connection on the TV (you may need to enter a PIN code).

If the function is missing, check:

• 🖥️ Support Miracast in Device Manager (section Network adapters should contain Microsoft Wi-Fi Direct).
• 🔄Updating video card and Wi-Fi adapter drivers via Windows Update.

For macOS (MacBook, iMac)

Apple not supports Miracast natively, but there are workarounds:

• 🍎 Use AirPlay with a set-top box Apple TV (if it is connected to Android TV via HDMI).
• 🖥️ Install third-party software, for example AirParrot or Reflector (paid solutions).
• 🔌 Connect the Mac to the TV via HDMI using an adapter (the most stable option).

Why doesn't macOS support Miracast?

Apple uses its own AirPlay protocol for wireless screen transfer, which is incompatible with Miracast. This is a marketing decision aimed at promoting the Apple ecosystem (including Apple TV).

3. Solving common problems with eShare

Even with proper configuration, users often encounter errors. Let's look at the most common ones and how to fix them.

Problem	Possible cause	Solution
TV does not find the device	Disabled Wi-Fi Direct or interference from other networks	Reboot both devices, turn off the VPN, check the distance
The image is slow or torn	Weak Wi-Fi signal or network congestion	Switch to range 5 GHz, close background applications
No sound during broadcast	The wrong sound source is selected on the TV	Check Settings → Sound → HDMI/ARC output
The connection breaks after 10-30 seconds	Energy saving on a smartphone or TV	Disable Adaptive brightness and Sleep mode on both devices

Critical feature: on some Xiaomi TV models (for example, Mi TV 4S) the eShare function is unstable when connected to a router in the 2.4 GHz band. Switch to 5 GHz or use direct Wi-Fi Direct.

If the image is transmitted with a delay (lag), try:

• 🎮 For games: reduce the screen resolution on your smartphone to 720p in the broadcast settings.
• 📺 For video: activate the mode Low latency in the settings eShare on the TV.
• 🔌 Connect the TV to the router via cable Ethernet (if supported).
