With laptops, you should Never
install a driver that comes from the company that made the parts.
OEM's like Samsung modifies the part a little bit to meet the requirements of its users.
You should install the drivers that came from your OEM company, in your case, Samsung.
Go to their website, download the drivers, and try to enable the Dedicated Graphic card within the Software that Samsung provided you with...
Forget the BIOS, it is OEM-Locked, so there aren't many options for you to mess around with.
-Hope it helps!
