Hello I have a bought an Inspiron 15; one year ago, and a thick line (several pixels) has appear at the bottom of my screen.
The problem occurs first one month ago and since this line is getting thicker.
If I try to print the screen, the problem doesn't appear in the screenshot. What should I do ?
If the line does not show when you print screen then it very well could be an LCD screen problem. Restart the system and at the Dell splash screen start tapping F12. Run full diagnostics with attention to the LCD results. If the screen is having trouble, as I suspect then it may need to be replaced. Have you tried to boot into Safe Mode and is the line visible there as well?
To boot into safe mode
Everything is pointing at a LCD screen problem.
