XPS15 9560 - There's a gray line about half an inch at the bottom of the screen
Can somebody help me how to fix with my laptop XPS15 9560, with a gray line about half an inch at the bottom of the screen. It used to be the task bar area and I can't see it so I put the task bar on the right. Thanks.
Please run the “LCD Test”, follow the steps below.
Switch off the computer > Press and hold down the ‘D’ key on the keyboard and press the Power button > you will see different colors on the LCD screen. During the LCD test please check if the grey and horizontal line appears?
Also connect an external monitor and check if the issue persists.
