Solving problem that a computer with two video cards cannot switch video card
Currently, computer is equipped with an independent display and a main display, so when using computer, it is necessary to switch video card, especially when playing games, so what should I do if dual video cards cannot be switched? How to solve problem that computer cannot switch video card? See details below.Solution:
1. The problem that dual graphics card cannot be switched mainly occurs on INTEL core graphics card. This is same reason as in Win8 system, and it is all caused by built-in graphics driver. To get a fully compatible built-in display driver, it is recommended to use system update function that comes with Win 10 system. The built-in display driver automatically updated by system can support dual display switching function.
2. In addition to excluding problem caused by integrated graphics driver, problem can also be caused by version of discrete graphics card driver. You can find latest driver on discrete graphics card official website, or you can update software through some drivers such as Driver Life or Driver Wizard.
3. Auto-switching may not support some software well, resulting in independent graphics card not being usable. We can manually specify software to use independent graphics card, or set it as a global independent graphics card.
