How does a computer dual graphics card switch to a standalone video card?

Today most computers have such a feature: CPU integrated core graphics card, plus the computer also equipped with a stand-alone graphics card, such a computer has dual graphics cards, under normal circumstances, dual graphics cards will automatically switch intelligent operation. However, due to the CPU integrated graphics performance is limited, not comparable to the independent graphics, in addition to the dual graphics computer running some games, it may also be compatible with the game can not install or flash. In this case, we usually need to switch the dual video card to a stand-alone video card to run, that is, specify the computer to use High-performance stand-alone graphics to run programs or games, so not only the best performance, but also can solve some compatibility issues.

So how does a dual graphics card switch to a stand-alone video card? In fact, it is very simple, first of all, we have to determine whether the computer is a dual graphics card, another check whether the dual graphics driver is installed normally, and then look at the independent video card is n card or a card, and then follow the following Below we will explain how the next dual graphics computer to switch to a stand-alone graphics operation.

　　NVIDIA (n card) independent graphics set dual graphics card switching Independent graphics method

First, in the computer desktop blank location, click the right mouse button, and then select the Nvidia Control Panel, as shown in the following figure.

Second, in the open Nvidia Control Panel, in the 3D setting on the left, click "Manage 3D Settings", and then in the "Global Settings" on the right, the option below the preferred graphics processor will be changed to "High-performance nvidia processor", and when you're done, remember to click "Save" at the bottom, As shown in the following figure.

This setting allows the dual graphics computer to switch to the default for stand-alone graphics high-performance environments run.

　　AMD independent graphics (a card) set dual graphics card to switch to the independent graphics method

First, the same is in the computer desktop blank location, click the Mouse "right", in the pop-up options, click "Configure interchangeable Display card", as shown in the following figure.

Second, then in the pop-up AMD can be switched display card settings, we can be set to run the independent graphics application to add in, and then choose "High-performance" can be completed, click on the bottom of the "save" on it.

The above is dual graphics computer set up dual graphics card only with a single display method, relatively simple operation, the above method for CPU core graphics card +a/n Independent graphics combination of dual graphics computer, if the computer with a two independent graphics card, no CPU integrated core graphics, then no need to set.
