If you have Win 10 installed, try starting the laptop in safe mode (start at Step.2).
If the display works in safe mode go to Troubleshoot > Advanced > Startup repair and follow the prompts.
In safe mode Windows loads its own generic hardware drivers so it may be that since it works in safe mode there is a problem with the display adapter drivers for the laptop.
