How to see the computer is not dual graphics card?

Dual graphics computer mainly has 2 kinds of situations: The CPU sets the display + The independent video card, the dual independent video card (possibly also includes the CPU integrated graphics card), is equivalent to more than two video cards, this situation most is in some high-end computer.

How to see the computer is not dual graphics card?

Want to see whether the computer is a dual graphics card, in fact, is very simple, there are a variety of methods, the following small series of simple for you to introduce 2 methods.

Method One, view in the computer Device Manager

1, on the computer desktop "Computer" icon on the right, and then select "Properties" in the Open Computer properties interface, and then click on the left of the "Device Manager", as shown in the following figure.

2, in the Open Device Manager, expand the bottom of the "monitor adapter", if there are two devices below, then the computer has dual graphics card, as shown in the following figure.

The picture above is the author notebook computer, wherein the HD4600 video card is the i7 processor's own core video card, while the GT 740M belongs to the independent video card.

Method Two: Use Master LU to see if the computer is dual graphics card?

Download and install "Master Lu" software in your computer, then switch to the top of the "Hardware Detection", and then click on the left side of the "graphics information", then the right side will display computer graphics information, the following figure, small knitting computer is still detected as two graphics cards, so you can determine that the small series of this notebook computer is dual graphics card, The same is true for desktop viewing methods.

Master LU See if the computer is a dual video card

Ps. At present, most Intel processors have built-in core graphics (except for the old CPU and E3 series processors), if the computer is equipped with a single display, so the basic need not to see also know is dual graphics computer. In addition, the AMD platform's APU processor also has built-in core graphics, while the AMD 760k/860k processor does not have a built-in core video card.

What are the benefits of dual graphics cards?

There are two main benefits of dual graphics:

1, if it is the CPU's own core graphics card and the combination of independent graphics, at present, this kind of combination can achieve dual graphics automatic switching, can play the role of energy saving, such as running the game when switching to a stand-alone graphics operation, and in general small software, office and so on will automatically switch to the core video card running, This can be in accordance with the need to freely switch graphics card, play a role in energy saving;

In addition, for the APU platform, some independent graphics card can also be combined with the APU Core video card delivery, can play a role in improving the overall performance of the graphics card;

2, if it is a number of high-end dual-independent graphics computer, then dual-independent graphics can achieve mixed delivery, the computer graphics performance will be stacked, the performance of a significant increase.

The above is how to see the computer is not a dual graphics card method, as well as the benefits of dual graphics. Of course, dual graphics cards will also have some deficiencies, such as easy to cause some compatibility problems.
