Screen Expansion – Operation Method for Computer Screen Expansion

In today’s rapidly changing technology, computers have become an indispensable tool in our lives and work. With the development of display technology, multi screen expansion has become an increasing choice for more and more people. Multi screen expansion can not only improve work efficiency, but also provide a broader perspective and better entertainment experience.

Screen extension, also known as multi monitor setup, refers to connecting a computer to multiple monitors to expand the workspace and improve work efficiency. Through screen expansion, we can display different applications or windows on different displays, thereby achieving more efficient workflows.

Connecting the monitor

To achieve screen expansion, the first step is to correctly connect the monitor to the computer. Most modern computer hosts have multiple video output interfaces, such as HDMI, VGA, DisplayPort, etc. You need to select the interface that matches the monitor, and then connect the monitor to the computer. After connecting, turn on the monitor power and ensure that the monitor correctly recognizes the signal source.

Set screen extension

After connecting the monitor, the next step is to perform screen expansion settings. The specific operation method for this step may vary depending on the computer operating system. Here are some common methods for setting up operating systems:

Windows system: Right click the blank space on the desktop, select Display Settings, select Expand these displays in the Multi display Settings drop-down menu, and then adjust the layout and orientation of each display.

MacOS system: Open the system preferences, select “Display”, check the “Mirror Display” or “Expand Desktop to Display” option, and then adjust the display arrangement and resolution.

 Using screen extensions

After completing the screen extension settings, you can start enjoying the convenience of multiple screens. Here are some tips for using screen extensions:

  1. Division of labor and cooperation: Placing different applications or windows on different displays to achieve division of labor and improve work efficiency. For example, editing documents can be placed on one monitor while searching for relevant information or performing other tasks on another monitor.
  2. Entertainment experience: With the multi screen expansion feature, you can watch movies or play games on one monitor while browsing web pages or handling other tasks on another monitor. This not only allows you to enjoy entertainment, but also keeps your work efficient.
  3. Picture in Picture: When watching a video, you can shrink the video window to a corner and perform other tasks in other areas. This allows for easy video viewing without leaving the workspace.
  4. Custom Layout: According to personal preferences and needs, the arrangement and layout of each monitor can be customized. By adjusting the size and position of the monitor, a work environment that suits personal habits can be created.
  5. Quick switching: When using multiple applications, it is possible to quickly switch between different displays, thereby improving work efficiency and response speed.


Although screen expansion brings a lot of convenience, there are also some issues to pay attention to during use:

Maintain appropriate distance: To avoid eye fatigue and discomfort, it is important to maintain a suitable distance between the eyes and the monitor. At the same time, attention should also be paid to adjusting the brightness and contrast of the monitor to protect visual health.

Avoid interference: When using screen extensions, avoid interference from the surrounding environment, such as strong light exposure, noise interference, etc. These interferences may affect the display effect and work efficiency.
