So, i've got 2 graphic card one AMD 8750M and Intel HD4000.
My problem is when i'd like to change the screen's backlight level that doesn't do nothing, but the HDMI works.
When i did a backup after that renamed to General Microsoft-Graphic card and after that the backlight control works but the HDMI not.
How to fix that problem? I want to adjust the backlight and use the HDMI at the same time. PLS HELP!
