I have a Thinkpad L430 with i5 processor and Intel HD graphics and intermittantly experience thin horizontal (the fill width of the LCD screen) grey lines move about my display. At first I assumed that the LCD screen is faulty as closing and reopening the laptop solved the issue. Today, however, the lines appeared on my external monitor??? but this time not the full width of the screen (20") only the width of the laptop screen? Again, closing and re-opening the laptop resolved the issue. I have the laptop docked and the display extended onto an external monitor. I have also had the issue using the laptop undocked. Do we think this could be a graphics card issue? Have you heard of this before?
