I have the Dell Inspiron 15R N5110. I can use the computer fine on a external monitor with no problem. But when I use the laptop screen it will freeze up and have white horizontal lines. It will get better or worse depending on how I bend it. I replaced the LCD cable and am still getting the same problem any suggestions?
There is nothing wrong with the screen or cable. I have the same problem and dell won't do anything and the fix that I found was put the screen in duplicate mode then change the resolution so you will have a full screen. It is working for me. My screen would go fuzzy at least 6 times a day. seems like it's cured now.
