Advice 1: How to combine 2 video

Often you can find motherboards that have two PCI-Express. These devices support the synchronous operation of two graphics cards to improve the performance of the graphics devices.
How to combine 2 video
You will need
  • drivers motherboard;
  • drivers graphics cards;
  • adapter.
Instruction
1
First, make sure that the motherboard of your computer supports synchronous operation of two graphics cards. Refer to the documentation to the motherboard. Find notes CrossFire or SLI. These modes are used for video card companies, ATI and Nvidia, respectively.
2
Select display adapters, of which you will synchronize. It is important to understand that this situation is not suitable for all graphics cards. Buy two graphics accelerators from the same manufacturer.
3
Make sure that the video cards support dual-channel mode. When choosing a video card ATI (Radeon), you can use cards of the same series. This means that the devices should have approximately like this: Radeon HD 5xxx.
4
Remember that the real performance of a more powerful graphics card will be reduced to a weak adapter.
5
Turn off the computer. Install both video card in the PCI-Express slot. In this situation, the monitor cable should connect to the devices via a special adapter. Standard display connection to the video card will not improve the performance of the graphics devices.
6
In that case, if you plan to connect to the adapters multiple displays, do not use an adapter-bridge. This scheme will allow you to expand the image on multiple displays
7
Install the drivers for the motherboard. Use the set of files and applications that activates the SLI (CrossFire) mode of operation of videoadapters.
8
Update the drivers for video cards. Launch the application and activate dual channel mode graphics accelerators. Configure the settings for the graphics cards. Disable unnecessary functions. Note that you will not be able to individually configure each charge. This means that both devices must be activated option.

Advice 2 : How to connect 2 graphics card

Connecting two graphics cards is a simple process, but requires knowledge of all the nuances of connection of two cards in one. To receive a "double portion" of the power of the graphics card should take into account all the subtleties of working with them, otherwise the desired result is obtained, and the second card in the system is just a side element. For a user of a personal computer that has been executing this task, it will be a failure.

You will need
  • Two SLI video card.
Instruction
1
If you are faced with this situation, as the lack of VRAM in the PC games industry, then two cards will add horsepower to your computer. This is the main reason of buying two graphics cards. Among other reasons can slip in the idea of being better than your neighbor who has only one video card.
2
Two cards can be joined with a special adapter that you can buy in a specialty store. The adapter connects both the video card and the image on the screen is transmitted by means of cable that connects to that adapter. Dual video cards can be used for other purposes: to connect to a single card computer monitor, and the other to connect your TV or second monitor. This method of using two video cards is called the "Second video output".
3
To connect two graphics cards, you should check their connection type. An important condition for the joint work of these boards will have the same connection types. The best option is a PCI card. If the cards will vary, we will not receive the desired effect. They will work, but appreciable growth we wouldn't notice. It is worth noting that when you install two graphics cards of different capacities should not forget that in the first slot you need to connect a more powerful card. When connecting two video cards the same brand, use innovation from Nvidia – SLI technology.

Advice 3 : How to combine two cards

Modern motherboards are available with two PCI-Exrpess. This improvement allows the motherboard to support the work with two graphics cards. Two video cards work in tandem, improving the graphics and overall computer performance. Also, this hardware solution will help to stretch the picture on two monitors.
How to combine two cards
You will need
  • - two graphics cards;
  • - special connectors.
Instruction
1
Carefully inspect the motherboard or refer to the documentation to her. On support work with two graphics cards would indicate the presence of two PCI-Express connectors, and mark SLI or CrossFire in the documentation or on the packaging. The connection type depends on the types of graphics cards. As a rule, connect only the same graphics card, that is, they must be from the same manufacturer and model of video cards must be identical.
2
Take two identical video cards. Make sure that both boards support the work in "command" mode. Examine the packaging or documentation on the video card — if it is a video card with Nvidia chipset, look on the package marked SLI, Radeon if – then mark must be CrossFire.
3
Install both graphics cards into the PCI-Express connectors, pre-unplugging power from the computer. Turn on the computer. After the operating system install to the hard drive software from the driver disk for the motherboard to activate dual graphics cards.
4
Implement the work of the two cards physically depending on the purpose of the modification. Connect the monitor using a special adapter, if you put two video cards to improve performance. Or connect the graphics card to two monitors, if you need to display a big size image. As a rule, two monitors can be connected with a single graphics card, so before combining carefully think about why you need it.
5
Do not experiment with hardware that does not support explicitly the dual mode operation. No additional firmware two graphics cards will not work together, if not met the above conditions.

Advice 4 : How to join 2 video

To connect a large number of displays to one computer, you must configure the synchronous operation of two graphics cards. This will allow you to consistently use 3 or 4 monitors at the same time.

You will need
  • - two graphics cards.
Instruction
1
Pick up a set of adapters that you will use. In most cases you can do an integrated graphics card and discrete graphics card. If your motherboard lacks a built-in video card, then use two full video card. In this case it is better to purchase the identical model video cards, but you can use devices from different companies.
2
Connect both video cards to the motherboard and turn on the computer. Install the software needed to configure both adapters. Of course, if you are using different graphics cards, install two sets of drivers, each of which will provide stable work of a particular adapter.
3
Connect the graphics card to external displays. If you are using a TV or TFT panel, it is better to connect them through the channels, transmitting a digital signal, e.g. HDMI and DVI-D. Even if the adapters are present three bands, it is better to use a pair of 2+2 and not 3+1. This will allow more or less evenly distribute the load between the graphics cards.
4
Open the settings of the TVs, if you use these devices. Specify as the primary video source the required ports (through which you made the connection). Turn on the computer and after loading the operating system, go to "Connecting to an external display". If the top of the window display not all new screens, then click "Find".
5
Configure the settings for joint work the desired displays. First select the primary device and activate the relevant function. Now select the graphics image of the other three displays and activate the option "Extend these displays". Remember that when you use graphics cards from different companies can cause problems with compatibility of drivers.
