Computer Screen Projection – Several Common Methods of Computer Screen Projection
Computer screen mirroring is a technology that transfers computer screen content to other display devices, which can help us achieve operations such as large screen viewing, conference display, and multi screen interaction. This article will introduce the principles, methods, and precautions of computer screen projection, to help you better connect and project your computer with various display devices.
The principle of computer screen projection is mainly to encode the computer’s display signal into a video signal, and then transmit it to display devices such as projectors and monitors through HDMI or VGA interfaces. After receiving the signal, these devices decode it into computer display signals to achieve the purpose of displaying computer screen content on other devices.
The key to achieving computer screen mirroring is to use the built-in HDMI or VGA interface of the graphics card to connect the computer with the display device. At the same time, corresponding settings need to be made on the computer to transmit display signals to other devices.
The method of computer screen projection
There are various methods for computer screen projection, and the following are some commonly used methods:
- Implementing screen projection using HDMI interface
One of the most common methods to achieve computer screen mirroring is to use the HDMI interface. First, you need to connect the computer and display device, then enter the computer’s BIOS settings and set the graphics card to HDMI output mode. In Windows systems, settings can also be made through the “Settings” interface. The specific steps are as follows:
(1) Connect the computer and display device through an HDMI cable;
(2) Enter the BIOS settings of the computer and set the graphics card to HDMI output mode;
(3) Start the computer and open the “Settings” interface in the Windows system;
(4) Select the “System” tab;
(5) Select the “Project to this computer” option;
(6) Set “Project to this computer” to “Always turn off”;
(7) Turn on the “Project to this computer” switch;
(8) Open the application or file that requires screen mirroring, and then select options such as “Screen mirroring to TV” or “Full screen mirroring”;
(9) Scan the QR code on the computer screen on your phone, and then select the device that needs to be used for screen mirroring to achieve screen mirroring.
- Implementing screen projection using VGA interface
Using VGA interface to achieve computer screen projection is also a common method. Firstly, it is necessary to connect the computer and display device, and then make the corresponding settings on the computer. The specific steps are as follows:
(1) Connect the computer and display device through a VGA cable;
(2) Enter the BIOS settings of the computer and set the graphics card to VGA output mode;
(3) Start the computer and open the “Settings” interface in the Windows system;
(4) Select the “System” tab;
(5) Select the “Project to this computer” option;
(6) Set “Project to this computer” to “Always turn off”;
(7) Turn on the “Project to this computer” switch;
(8) Open the application or file that requires screen mirroring, and then select options such as “Screen mirroring to TV” or “Full screen mirroring”;
(9) Scan the QR code on the computer screen on your phone, and then select the device that needs to be used for screen mirroring to achieve screen mirroring.
- Using Bijie wireless screen projector to achieve screen projection
The Bijie Multimedia Collaboration System is a convenient and flexible screen projection device suitable for various scenarios. Wireless screen mirroring protocols such as Miracast, WiDi, and AirPlay can be used to achieve wireless screen mirroring. These protocols can wirelessly transmit computer screen content to display devices that support the corresponding protocol. The specific steps are as follows:
(1) Ensure that both computers and display devices support wireless projection protocols such as Miracast or AirPlay;
(2) Connect the Bijie wireless screen projector to the display screen, ensuring that the computer and the projector are connected to the same local area network;
(3) Start the computer, then Win+P calls up the screen projection option;
(4) Select “Copy” or other options, then select the name of the projector device and click on “Connect”;
(5) After successful connection, select the file that needs to be projected.
