I have my Lenovo W520 attached to a Dell monitor via HDMI. When I want to use the laptop without the attached monitor, I switch the NVidia Prime profile to Intel Power Saving Mode. It's the only way I can get the laptop to work. But when I do that, I get the black borders everyone is talking about. And I can't get rid of it - I tried all the solutions.
