Win10 dual graphics card can not switch the solution

  

Now most Win10 notebooks are dual graphics, dual graphics switching can make Win10 system balance between performance and energy saving. However, some users' Win10 dual graphics cards can't be switched. What is going on?

The reasons of:

Windows 10 installed on the test system in a dual graphics card models, the phenomenon appears more discrete graphics software can not be used, even if the set switching software The use of a discrete graphics card, but the actual application 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 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).

Steps to solve:

1. Most of the problems occur in the INTEL core graphics card. According to the detection of multiple computers, the same reason as this problem occurs in Win8 system. Both are caused by the set display driver. 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 of integrated graphics driver 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.

The above is the solution for Win10 dual graphics card can not be switched, this problem is mainly due to the lack of compatibility of Win10, I hope to be improved in the official version.
