I basically need help with this. I was reading around. And had heard changing something in Bios. But my Bios doesn't have a Video tab or anything related to the Video. I have a external GPU that is an AMD Radeon HD 6450 and a integrated Intel 4000 in my Sager/Clevo(W240EU/W250EUQ/W270EUQ). Not quite sure what my motherboard is. Right now I am running my External GPU on a 28inch TV. While my laptop is just sitting on the table with it's monitor black and not working.
