Two monitors simultaneously use one to watch a movie (1)

The computer is now powerful and can do a lot of things. Moreover, computer hardware is not expensive, especially the price of the display has dropped to a very low level. If we have dual monitors, we can drag and drop some programs, such as Thunder, to the second monitor to better focus on the main display. Most of the current graphics cards have 2 or even 3 interfaces, which can fully support dual or multiple displays. In doing so, we can completely do the entertainment work, and enjoy the thunder in the second monitor.

Step 1: Select the interface and double display

Connecting the dual display is very simple. Just connect the video cable according to the video interface provided by the computer graphics card and display device. Nowadays, there are many types of video interfaces provided by the graphics card. In addition to the traditional S-Video and VGA interfaces, there are also color difference interfaces, DVI interfaces and HMDI interfaces. The first three are analog interfaces, and the latter two are digital interfaces. According to the interface provided by the second display device, we can use different interfaces to connect. Connecting a CRT monitor or a low-end LCD monitor generally uses an S-Video or VGA interface, and if a high-end LCD monitor is used, a color difference interface, a DVI interface, and an HMDI interface can be used.

DVI and HDMI are highly recommended here, especially HDMI. One line of HDMI can support both digital video and digital audio transmission. The highest version is 1.4 and the popular version is 1.3. Figure 1 is a rear view of a display, VGA, DVI, HDMI interface is readily available. Figure 2 shows the HDMI connection, and the HDMI connection transmits digital signals without compression. Moreover, the HDMI cable simultaneously transmits video and audio, eliminating the need for digital audio wiring. In addition, the length limit of the HDMI cable is also less than that of the DVI. Generally, even if it is 20 meters away, the image quality will not be affected.
