How does 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.
