  1. A narrow red line appears at the top of the display


    Hi All,

    A week before, my dell LED monitor for desktop started to show a narrow red line at the top of the display with the screen flickering at times. Now the red line appears frequently and flickering has increased to a point where I can't work smoothly. Is the display gone? Or is it the issue with the Motherboard or RAM? Can it be repaired or should I buy a new one?

    Red Wavy Lines appear in edge

    Hi,

    I would request you to reset the edge settings and then check if it helps.

    Refer the steps below to reset Edge.

    Steps:-


          • First of all launch Microsoft Edge Browser.

          • After that click on “More action” option which is visible at top right side of the browser and you will see “Settings” option.

          • Under “Settings” scroll down and you will see a button “Choose what to clear” under “Clear browsing data” option.

          • Once you click on this option you will see list of feature like
    • Browsing History
    • Cookies and saved website data
    • Cached data and file
    • Download history
    • Form data
    • Password.

    Please revert if the red wavy lines appear while using edge.

    Thank you.

    Red and Blue Lines Appear On Screen


    Edit: Sorry, I didn't notice that you were on a laptop. The below is from when it happened to us on a desktop computer.

    I can only tell you what happened to us....

    On my partners desktop there appeared one day a thin red line running from top of screen to bottom while playing Minecraft, then that thin red line was there on desktop too, then one day a blue line appeared about 3 inches away also running from top of screen to bottom.

    I had just bought a new Nvidia GTX 960, so I gave him my old GTX 460, he installed it and the lines were still there. He grabbed one of my old monitors out of the laundry room and boom, lines were gone. Apparently it's not only graphics cards going bad that exhibit this but flat panel monitors as well.

    So, if you've got an extra monitor (or somebody else in the house has one) try swapping it out to see if the lines go away before plonking down cold cash on a new graphics card.

    Red Wavy Lines appear in edge

    Hi,

    Sorry to hear that you are still facing the issue.

    Just to clarify, are you referring to the auto correction red lines that appear when you type in the address bar in Microsoft Edge?

    It would be helpful if you could attach a screenshot of the lines that you are referring to. Follow the steps provided by one of the MVP on
    How to include a screenshot in your post

    Get back to us with the response.
