The graphics card has three interfaces, one of which is connected to the monitor, and the other two

The graphics card has three interfaces, generally one is the DVI interface.

A VGA, as well as an HDMI or S-terminal interface. They can all be connected to the display, but the interface is different and the output signal is different.

Graphics card (video card, graphics card) is the full name of display interface card.

Also known as a display adapter.

It is one of the most basic configurations and important accessories of the computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics. The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

Is it a A card or an N card? The three interfaces of the N card are like this,One is the DVI interface,A VGA or DVI,The other HDMI or S terminal interface,The current civilian-grade graphics card of the N card can be connected to two monitors for split screen,Three screens,It seems to be difficult,If it's not HDMIs is the S terminal,That's for connecting to the TV,Use a S terminal line to connect the color difference line to the old TV with a card Now it's generally a DVI or VGA,Plus a Dispalyport, Or is the mini dp interface, plus an HDMI interface, but a card from 5830 after the card, it seems to be four interfaces, generally two DVI + DP or mini DP + HDMI, anyway, the back of the interface, can be connected to the display, *** or VGA are connected to the general display, S terminal connected to the TV, HMDI to the LCD TV with HMDI or LCD with HDMI, you can also use HDMI to VGA or DVI

1. If you want to connect a computer host to three display screens, you must first have an independent graphics card equipped with three independent first-line interfaces, VGA interface, DVI interface and HDMI interface.

2. The first display: When wiring, plug one end of the VGA cable into the VGA interface of the independent graphics card of the host, and the other end at the VGA interface of the display.

3. The second display screen: plug the HDMI interface end of the HDMI to VGA interface cable on the HDMI interface of the independent graphics card of the computer host, and then plug one end of the conventional VGA interface cable into the converted VGA interface female, and the other end into the VGA interface of the computer display.

4. The third display: plug the VGA end of the DVI interface to VGA interface cable on the VGA interface of the computer display, and plug the DVI interface into the DVI interface of the independent graphics card of the host.

<>6. After the wiring is connected, you can press the "Windows+P" key combination on the keyboard to adjust the display mode of the three screens, you can choose three screens to splice the display, or you can set the three screens to display the same thing, this is set according to your own needs.

7. And then it's done.

1. To realize the connection between the computer host and the three displays, the independent graphics card that supports the host must first have three independent graphics card cable interfaces, VGA interface, DVI interface and HDMI interface.

2. The first display: When wiring, insert one end of the VGA cable into the VGA interface of the independent graphics card of the host, and the other end into the VGA interface of the display.

3. The second display: insert the HDMI port of the HDMI to VGA interface cable into the HDMI port of the independent graphics card of the computer host, and then insert one end of the traditional VGA interface cable into the converted VGA interface, and the other end into the VGA port of the computer monitor.

4. The third display: plug the VGA end of the DVI interface and the VGA interface cable into the VGA interface of the computer monitor, and then insert the DVI interface into the DVI interface of the independent graphics card of the host.

<>6. After the wiring is completed, you can press the "Windows + P" key combination on the keyboard to adjust the three-screen display mode, you can choose the three-screen splicing display, or you can set the same content for these three screens, which is set according to your own needs.

7. It's done in the end.

Notes:

1. The graphics card strengthens the power interface, please don't forget to plug it in when installing.

2. The heat sink begins to cover the video memory, and the heat sink completely covers the surface of the video memory, so that the heat of the video memory can be volatilized at the fastest speed and reduce the temperature of the video memory.

3. Please install the latest driver of the graphics card.

4. When you don't know how to operate, you must find a professional person to deal with it.

5. Do not disassemble the computer at will.

Yes, there are some graphics cards that have two HDMI connectors. For example, the AMD Radeon RX 580 8GB graphics card has two HDMI ports, which allows the cluster to support 4K** output and AMD FreeSync technology for a smoother gaming experience. In addition, the NVIDIA GeForce RTX 2080 Ti graphics card also has two HDMI ports, and it supports the latest NVIDIA Turing architecture, which can provide faster gaming performance and higher image quality.

In addition, there are some other graphics cards such as AMD Radeon RX 570 4GB graphics card, NVIDIA GeForce GTX 1080 Ti 11GB graphics card, etc., which also have two HDMI ports.

Split-screen requires an HDMI interface and an HDMI splitter.

Connect the monitor with an HDMI cable and an HDMI splitter, if the monitor does not have an HDMI interface, you need to use HDMI to VGA or HDMI to DGI.

The two can't watch movies and play games at the same time, and the splitter is a picture with multiple monitors at the same time, which does not meet the needs.

If you have to connect 1 HDMI to 2 monitors, those 2 monitors can only display the same content, and in some cases there are compatibility problems, such as 1 display, 1 no display, or buy a switch switch, switch to which display which display.

No way.. Two monitors can only display the same content on two monitors... Two monitors connected to the same computer, one watching movies and the other playing games??? Then you can try to put half of the movie window and the other half of the display range for playing games.

It's simple.,Go to the computer city and buy a VGA branch.。

Can you take a look at the picture above?

The splitter is estimated to be used for multiple displays at the same time, which does not meet your needs.

There is a point 2 of the interface cable sold.
