Wireless screen mirroring – What is the DLNA wireless screen mirroring function?

DLNA wireless screen mirroring function is a wireless screen mirroring technology based on the DLNA protocol. It allows users to wirelessly connect multimedia content from mobile phones, computers, tablets, and other devices, such as photos, videos, music, etc., to a TV or large screen, achieving the effect of watching on a large screen.

 Introduction to DLNA Protocol

The DLNA protocol is a file based protocol that supports the encapsulation and transmission of various types of multimedia content, including audio, video, images, etc. It can deliver multimedia content from devices to other devices, such as TVs, speakers, etc., on the same WiFi network, achieving wireless connection and screen mirroring display.

DLNA Wireless Screen Projection Features

  1. Cross platform: DLNA wireless screen projection technology not only supports mobile devices such as Android and iOS, but also desktop devices such as Windows and Linux, allowing different devices to connect and transmit to each other.
  2. Wireless connection: Users do not need to use cables or docking stations, they can achieve wireless connection and screen mirroring between devices on the same WiFi network.
  3. Multi format support: The DLNA protocol supports multiple multimedia formats, including common audio, video, and image formats, allowing users to freely transmit and share multimedia content between different devices.
  4. Smoothness: Due to the efficient transmission mechanism adopted by the DLNA protocol, users can enjoy a smooth and stable viewing experience when watching the projected content.
  5. Adaptive Resolution: The DLNA protocol can automatically adjust the screen projection resolution based on different devices and network environments, ensuring clarity and smoothness of the image.

How to implement DLNA wireless screen projection function?

  1. Confirm device support: To use the DLNA wireless screen projection function, it is necessary to first confirm that the device supports the DLNA protocol. Generally speaking, modern smart TV, audio and other devices have built-in support modules for the DLNA protocol. For devices such as mobile phones and computers, corresponding DLNA protocol software or plugins need to be installed to achieve wireless screen mirroring function.
  2. Connecting to the same WiFi network: To use the DLNA wireless projection function, all devices need to be connected to the same WiFi network. Ensure that the TV, audio, and other devices are connected to the home network or public WiFi hotspot.
  3. Enable DLNA service: On devices such as televisions or audio systems, turn on the corresponding DLNA service switch. Find the “Network Settings” or “Wireless Screen Projection” option in the device menu and enable the DLNA function.
  4. Search for devices: Open DLNA applications or plugins on devices such as mobile phones or computers, and search for available TV or audio devices. Generally speaking, applications will list connected devices on the same WiFi network.
  5. Select content transfer: Select the device you want to project from the list of available devices found, and then select the multimedia content you want to transfer, such as photos, videos, or music. The application will automatically transfer the content to the selected device and start playing on the large screen.
  6. Adjust display settings: After the transmission is completed, users can make some display settings adjustments as needed, such as adjusting resolution, audio output, etc. Some devices also support mirror display function, which means that the phone or computer screen is directly mirrored onto the TV or large screen.


  1. When using the DLNA wireless screen projection function, it is important to pay attention to protecting personal privacy and data security. Do not transfer sensitive information or private content through DLNA.
  2. If there are issues such as lagging or delay during transmission, you can try checking the stability of the network connection or restarting the device and router.
  3. Different devices and applications may support different versions and features of DLNA. When encountering problems, you can consult the official documentation of your device or application for more assistance.

In summary, the DLNA wireless screen projection function is a very practical technology that allows users to more conveniently project multimedia content from mobile phones, computers, and other devices onto televisions or large screens, enjoying a more comfortable and convenient audio-visual experience. Whether it’s watching movies, sharing photos, or presenting meetings, the DLNA wireless screen projection function can bring users a better audio-visual effect and interactive experience.
