I am using a Dell Inspiron 14r, whose display screen is not working properly. It's just a white and dotted black screen, right now I can't buy a new one, I am using Window 8. So I made my laptop connect with an old PC monitor using a VGA cable. But now my laptop overheats faster; I can't even play games which leads the laptop to power off after some time. So I want to ask: is my GPU rendering two screens at a time?
- Defective laptop screen.
- Monitor connected via VGA.
If so, then what can I do to render only my monitor screen via VGA?
