My friend's laptop boots but it won't show anything. We tried connecting it to a TV throug HDMI and it works fine this way. We also could remove the HDMI after it starts correct, and it still worked. We could also start correctly with the HDMI in the laptop only. But when we start without HDMI it just shows a black screen.
Thanks!
 
Solution

You can try to uninstall an reinstall the display drivers. It sounds like the driver stored a wrong profile for the display.
