How to use WiDi wireless projection technology?

As is well known, Bijie Multimedia Collaboration System supports screen casting protocols such as AirPlay, Miracast, WiDi, Googlecast, HUAWEIcast+, BJcast+, etc. How to use the WiDi projection protocol among them?

WiDi wireless screen mirroring is a wireless screen mirroring technology based on the WiDi protocol, which allows users to wirelessly connect multimedia content from their phones or computers, such as photos, videos, music, etc., to a TV or large screen, achieving the effect of watching on a large screen. The following will introduce the usage method of WiDi wireless screen projection.

Introduction to WiDi Protocol

WiDi (Intel Wireless Display) is a wireless projection technology launched by Intel Corporation. It is based on Wi Fi networks and supports the projection of multimedia content from mobile phones, computers, and other devices onto televisions or large screens. The WiDi protocol is similar to the DLNA protocol and is also a file based protocol that supports multiple multimedia formats, including audio, video, images, and more.

Features of WiDi wireless screen projection function

  1. Wireless connection: WiDi wireless screen mirroring does not require the use of cables or docking stations. It only requires wireless connection and screen mirroring between devices on the same Wi Fi network.
  2. High definition: The WiDi protocol supports high-definition video transmission, allowing users to enjoy the same high-definition image as on their devices on a large screen.
  3. Low latency: Due to the efficient transmission mechanism adopted by the WiDi protocol, users can enjoy a low latency and smooth viewing experience when watching the projected content.
  4. Multi device support: WiDi wireless screen projection technology not only supports mobile devices such as Android and iOS, but also desktop devices such as Windows and Linux. Different devices can be connected and transmitted to each other.
  5. Security: The WiDi protocol has undergone rigorous security testing and verification, so users do not need to worry about data security and privacy breaches.

How to implement WiDi wireless screen mirroring function?

  1. Hardware preparation: To use the WiDi wireless projection function, it is necessary to first ensure that the TV or large screen supports the WiDi protocol. In addition, users also need to have a WiDi enabled transmitter (usually WiDi Dongle) and a receiver compatible with the transmitter. Connect the transmitter to the HDMI interface of the TV or large screen, and plug the receiver into the device that needs to be projected (such as a computer or phone).
  2. Software preparation: Open the WiDi receiver application on the TV or large screen. This application is typically located in the “Apps” or “All Apps” list. On the receiving device (such as a computer or phone), open the corresponding WiDi application or plugin. These applications can be downloaded for free in the app store.
  3. Connect to Wi Fi network: Ensure that both the TV and receiving device are connected to the same Wi Fi network. This can be achieved by sequentially entering the device’s “Settings” menu and selecting the “Network” option. Select the Wi Fi network you want to connect to on the TV or large screen, and enter the password to connect.
  4. Start screen casting: Open the content to be cast on the receiving device, such as photos, videos, or music. Then select the “WiDi” option and start searching for available projection devices. If the WiDi receiver application on the TV or large screen is already open, it should be listed in the list of available devices. Select the device you want to project and start transmitting content.
  5. Adjust display settings: After the transmission is completed, users can make some display settings adjustments as needed, such as adjusting resolution, audio output, etc. In the WiDi receiver application on a TV or large screen, you can find the corresponding settings options to adjust.
  6. End screen casting: After the user completes the transmission of screen casting content, they can end the screen casting by closing the WiDi application or plugin on the receiving device. At the same time, the WiDi receiver application on the TV or large screen can also be turned off.


  1. When using the WiDi wireless screen mirroring function, it is important to protect personal privacy and data security. Do not transfer sensitive information or private content through WiDi.
  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 WiDi. When encountering problems, you can consult the official documentation of your device or application for more assistance.
  4. WiDi wireless screen projection technology requires certain hardware support, such as TV and audio devices that support the WiDi protocol, as well as compatible transmitters and receivers. Therefore, it is necessary to confirm the compatibility of the equipment and accessories before purchasing.
  5. The application of WiDi wireless screen projection technology is subject to certain limitations, such as being unable to be used in public places or environments without Wi Fi networks. At this point, users can consider using the wireless screen mirroring function of mobile devices or other similar solutions.

In short, WiDi wireless screen mirroring 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, WiDi wireless screen mirroring can bring users a better audio-visual and interactive experience.
