Hello this could be a driver software problem.
Visit intel here:

http://www.intel.com/p/en_US/support/detect

And run the driver update utility.
Download the driver if a new is found.
And install it.
You need to reboot, when you have installed the driver

Try also to visit the mainboards homepage, for the latest drivers.

Check also the screen cable for damage or loose connection.
But ofcourse the screen could have a fault also.
Test with another screen.

Good luck
