Win10 screen brightness adjustment is invalid. Solution

WIN10, WIN8 A lot of computer graphics card driver installation can not adjust the brightness of the computer screen, even if the adjustment is maximum. This is due to Intel's i series (Core i3, i4, i5, i7) CPU integrated graphics driver, especially the first generation CPU core driver. In addition, the dual graphics card computer can disable the CPU's display, using a discrete graphics card. For the former case, you can try the old version of the graphics card driver, and you may be able to solve it. Because there are many reasons involved, such as the brand of the computer is different, the CPU is different, and the CPU of the i series is several generations. If the official brand of the computer brand does not have the latest drivers available, you can only find compatible drivers online.
