Win10 dual graphics can not switch

Now, the computer we buy is basically dual graphics, dual graphics computer can make Win10 system balance between performance and energy saving. This is very good for the user, but recently some users said that the dual graphics card can not be switched under the win10 system. What is going on? Below, U Daxia Xiaobian will introduce how to solve the problem that Win10 dual graphics card can not be switched. .

Win10 dual graphics card can not switch
Reason analysis:
Windows 10 system in the test installed on the dual graphics card model, more software can not use the discrete graphics card, even in the switching software It is set to use a discrete graphics card, but the actual graphics can not use the discrete graphics card, the test still uses the core graphics card inside the integrated CPU, which can not achieve the effect of graphics card acceleration. The following is an example of Windows 10 Technical Preview Build 10074 (there may be changes after the official version is released, for reference only).
Resolve steps:
1, most of the problems appearing on the INTEL core graphics card, according to the detection of multiple computers, the same reason as this problem occurs in Win8 system, are due to the set display driver Caused. Therefore, in order to ensure that a fully compatible set display driver can be obtained, it is recommended to use the system update function provided by the Win10 system, and the set display driver automatically updated by the system can perfectly support the dual display switching function.
2. Excluding the possibility that the integrated graphics driver will cause problems, the discrete graphics driver version may also cause problems. You can find the latest driver version on the independent graphics card official website, or you can upgrade it with software such as driver life through some driver update software.
3, because automatic switching may not support some programs, resulting in the inability to use the unique situation, you can manually specify the software to use a discrete graphics card, or set to a global discrete graphics. The operation method is similar to Win7 or Win8.
