Samsung NP370-R5V Backlight Control Fail

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!

Thanks for joining the Graphics community.

Is backlight control similar to brightness control?

This is because our graphics driver does not have a feature called Backlight control.

Thanks
