I recently just ran into a problem where my HP Envy m6 laptop monitor wont display anything. the screen lights up but no actual images/text appear. I am able to change my brightness. When i plug it into an external source everything is fine. When i Duplicate the screens it still will not show up on the laptops actual monitor but the external one will be fine. I have already tried soft resets and restarting it. NOTE: The screen is NOT dead. Lights up and can change brightness.
