Win10 dual graphics card can not switch how to solve

Many users have upgraded their notebooks to Win10 and found that their notebooks are dual graphics cards. Dual graphics switching can balance the performance and energy savings of the Win10 system. But some users' Win10 dual graphics card can't switch, what's the matter? Then, Win10 dual graphics card can't switch how to solve it?

Win10 dual graphics card can't switch how to solve
Cause analysis:
Windows 10 system is tested on the model installed on the dual graphics card. There are more cases where the software cannot use the discrete graphics card. Even if the discrete graphics card is set in the switching software, the discrete graphics card cannot be used in the actual application. The integrated core graphics card inside the CPU 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 the 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.
The above is the solution that Win10 dual graphics card can not switch, this problem is mainly due to the lack of compatibility of Win10, I hope to be improved in the official version.
