How to install dual graphics cards on a computer?

Hello landlord, maybe you don't know much about dual card work.

Dual-SIM mode: Nivida has a SLI, and AMD has a Cross Fire, both of which hand over the data from one screen to two graphics cards.

Similar to the landlord's host, this kind of independent graphics plus integrated graphics host,Can't let two graphics cards work at the same time。

Yes, but only the integrated graphics on AMD's motherboard can be completed with AMD's discrete graphics.

If the landlord wants to connect two monitors, don't think about the integrated graphics card you have. Focus on the independent graphics card, see how many signal output interfaces the independent graphics card has, generally the current graphics card has two or 3 output interfaces (dual DVI, VGA+DVI, dual DVI+S terminals, dual DVI+HDMI, VGA+DVI+S terminals, VGA+DVI+HDMI), which can perfectly achieve multi-screen display.

So, if the landlord wants to connect two monitors, first make sure that your discrete graphics card has several ** signal output ports. If there are two or three, just press the corresponding interface, connect the corresponding real device, and then set the display mode to "dual-screen copy" in the graphics card settings panel. Thank you

No, you need to connect the two monitors and plug them directly into the independent graphics card, and set the desktop properties.

Dual N cards with N card support for SLI and Dual A cards with A card support CF can improve the performance of the graphics card and work at the same time.

Take AMD graphics card firefight as an example, and introduce the steps of graphics card firefight:

1. Right-click on the blank space of the desktop and select "Show Card Properties", as shown in the figure below.

2. Go to "Display Card Properties".

3. In the "Graphics Card Properties", select "AMD Radeon Dual Graphics" under "Performance".

4. Select "Enable AMD Radeon Dual Graphics" to enable the Hybrid Crossfire Technique.

Today's computer host graphics cards are multi-interface, and the standard interface is HDMI DP. As long as you select the corresponding interface, directly infiltrate the insertion, and set it in the display properties. The operation is in.

1. The monitor is directly linked to the corresponding interface of the graphics card. (HDMI plug HDMI, DP plug dp) <>

2. System - display settings, there are two display modes: copy mode and extended mode. Select the extended mode and OK. (Copy mode is where two displays display the same content; Extended mode is when the two displays display different content).

The computer is set up with two monitors, and with a mouse and keyboard, the operation method of operating the second monitor is as follows:

1. Dual-screen application operation:

There are two display modes for dual computer monitors: copy mode (i.e., "copy these displays") and extended mode (i.e., "expand these displays" in the previous step). Replication mode is where both displays display the same content; Extended mode is when two displays display different content, and they correspond to different application scenarios.

1. Operation of extended mode: In general, the common method of dual-screen display is to use the second monitor (called the secondary display) for non-recurring operations such as automatic (or to extend the game map to the secondary monitor), the main monitor can be used for regular operations such as Internet browsing, and then on the main display screen first, and then the non-full-screen display (the window can not be moved if the window is maximized) The **** software window is dragged to the right side by holding down the left mouse button, Until the screen appears on a secondary display (such as a TV), then maximize or display it in full screen. Then, go back to the main display for recurring operations.

If you need to return to the secondary display, simply move the mouse cursor to the side of the secondary display until it appears on the secondary display.

2. Operation of copy mode: the display content of the main display and the secondary display are exactly the same, which is mainly applicable to business applications, such as the main display for business users and operated by them, and the secondary display for customers to show the content that business users need to show to them and all the operation processes of the mouse and keyboard on the main monitor.

2. System settings (take win7 system as an example): The replication mode and expansion mode of the above dual-screen operation need to be set in the system in advance.

1. Right-click on the blank space of the desktop - screen resolution to enter the "Change the appearance of the monitor" window.

2. In the pop-up window, if the display 2 does not appear (generally it will be automatically recognized and displayed), then click "Detect" or "Identify" to set the appropriate resolution for the display balance 1 and 2 respectively. As shown in the figure below:

3. In the "Multiple Monitors" option, click the inverted triangle and select "Expand these displays" (so that the settings can make the display content of the two monitors different) or copy these displays (the content displayed by the two monitors will be the same), and then confirm.

Note: 1. A computer can install and use multiple mice and keyboards, but not two mice or keyboards at the same time.

2. A mouse or keyboard cannot be operated on two displays at the same time.

Two independent graphics cards are improved using SLI (N-card) or CrossFire technology (A-card).

1: Make sure the motherboard is a dual graphics card.

2: Installation method.

Description: 1. Generally, the motherboard will integrate a graphics card, and then install a discrete graphics card, which is also called a dual graphics card.

2. Gamer terminology - Dual Card Crossfire is the above legend, install two independent graphics cards. The motherboard used has 2 physical x16 PCI Express slots.

3. Dual-card firefight, increase computing performance, NVIDIA's similar technology is called SLI bridging technology. The goal is often to dramatically increase the graphics processing power of the entire computer, so that 3D games can run better.

4. It needs to be set up correctly.

1: Ensure that the graphics card chip model is consistent.

2: If your motherboard supports SLI, or CF, the motherboard package has a bridge, plug in 2 cards, and then buckle the bridge (N card uses the bridge of SLI).

3: You only need to install the driver once.

4: Just plug the monitor plug into the first graphics card, this is the main card, (the card closest to the CPU is), the second card is the secondary card, no need to connect.

5::Open the graphics card control panel,Turn on the dual card operation,Note:You must install a new driver,Because the old driver generally does not have a dual card to open the control surface,But as far as the GTX660's built-in disc driver is concerned, it should have this function。

6: Pay attention: Is your power supply and CPU strong?

I wanted to send you a picture, but unfortunately the host of my dual card is out of order and is in the maintenance point.

You can only use one graphics card, but there used to be one graphics card with dual monitors, so look for it.

Graphics cards originally came with some motherboards. If you don't feel good, if the motherboard supports an external discrete graphics card, you can buy it yourself and add one.

When installing the driver, only the external graphics card driver can be added.

This is a dual graphics card, but you can only use one

There is a problem with the connection. There's always a way to pick up two. The point is that there is something wrong with your usage. 23 games to play,. Can't watch qqyy?

Look at qqyy with 19 again? The point is that the two monitors show exactly the same picture. Are you playing on a different monitor? And it will only be troublesome and will not be convenient. There is no superfluous use, (if only for your own use.) 19 That's still the case.

23 What is not enough.

You can use the HDMI interface to achieve split screen, and prepare an HDMI splitter first.

1. 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.

2. After connecting, right-click on the computer desktop and click to display the settings.

3. Click to detect, this is the number that the rest of the monitors will display 1 n, and then assign the display content of each display.

Hello: Your request is for two monitors to show different interfaces?

This requires hardware, and the crossover alone cannot solve the problem.
