To find the brightness slider in earlier versions of Windows 10, select Settings > System > Display, and then move the Change brightness slider to adjust the brightness. If you don't have a desktop PC and the slider doesn't appear or work, try updating the display driver.
If you had tried so many ways but still not getting solution i would suggest you to use any third party apps. Those apps adds visual enhancements on an OS level. Also please check graphics control panel once.
