Are you sure it wasn't dropped, or sat on, or something like that?
I very much doubt a change of driver can fix that type of problem.
It sounds like the LCD screen itself has been damaged.
WE HAVE TRIED TO INSTALL ALL KINDS OF DRIVERS TO REPAIR IT WITHOUT MUCH SUCCESS. IT HAS NOT BEEN DROPPED IN ANYWAY. LCD SCREEN LOOKS FAULTY. BUT WE TRIED TO USE A SECOND SCREEN WITHOUT MUCH SUCCESS.
