Extended information

LCD monitor is a liquid crystal monitor. The advantage is that it has a thin body, a small footprint, and low radiation. It gives people the image of a healthy product. However, the LCD screen may not necessarily protect the eyes. This depends on each person's computer usage habits.

The working principle of LCD liquid crystal display is that there are many liquid crystal particles inside the display. They are regularly arranged in a certain shape, and the colors on each side of them are different: red, green, and blue. These three primary colors can be restored to any other color. When the monitor receives the display data from the computer, it will control each liquid crystal particle to rotate to a different color surface to combine into different colors and images. Also because of this, the disadvantages of LCD screens are that the colors are not bright enough and the viewing angle is not high enough.

How to set up dual monitors to display this function in Win7

1. First, right-click the mouse on a blank area of ​​the win7 desktop and select the "Screen Resolution" option.

2. If you have two monitors installed, the following picture will be displayed. If the two monitors are not displayed, click "Detect" to detect, and then click the button box behind the multiple monitors. See the two options "Copy these displays" and "Extend these displays";

1) If you choose "Copy these displays", you will see exactly the same Windows window on both monitors, which is suitable for teaching demonstrations, places where multiple people can display the same content, and also suitable for conference venues and outdoors. Business presentation.

2) If you choose the "Extend these displays" option, the extended mode means that the content of one display is expanded to two displays, and continuous and different content is displayed. At the same time, we can define horizontal or vertical addition by ourselves. , for this state, it is suitable for software and functions that require more delicate effects such as video editing, audio editing, and graphic design.

Dual display requires hardware support. The graphics card must have more than two output interfaces, such as one DVI and one VGA. After connecting the monitor, turn it on. During the power-on self-test, both monitors will be turned on, and When the same content is displayed, one of the monitors will automatically turn off after entering the operating system. This is because the dual-screen display function in the system is turned off by default, and the monitor that remains on is connected to the primary display interface of the monitor. The closed monitor is connected to the (Slave) display interface.

At this time, you need to install the latest driver of the graphics card to set the dual-monitor output parameters. For example, the nVIDIA graphics card uses nView in the ForceWare driver to achieve the dual-monitor function, while the ATI graphics card uses HydraVision technology to achieve it. Taking the ATI graphics card as an example, after entering the system, you can see 2 monitors in the display property settings. If it is the first time to use it, the second monitor will be gray, indicating that it is not enabled.

Double-click the second monitor, and the system will pop up a dialog box asking whether to enable the monitor. Regardless of whether it is an ATI graphics card or an nVIDIA graphics card, in addition to displaying the same screen content on two monitors, it can also display different content on two monitors on the same host. Taking the nVIDIA graphics card as an example, install the driver After that, enter the display attribute driver setting interface, click "nView" in the extension window, and in "nView mode", you can set it to "Copy", "Platform Across" or "Vertical Across" as needed
