I have a Latitude D810 and it has a blue line on the monitor, how do i get rid of it thanks redhatter13
Most likely, you will need to replace the screen. Attach an external monitor - if the line does not show on that, then the screen needs to be replaced. If it does, you likely have a bad video chip.
it was not there a week ago had to factory restore, then it appeared, on another monitor, it is still there.
If the line shows both internally and externally, replace the video card.
