  1. Problem with horizontal lines across screen on boot


    Dell Inspiron i5 laptop
    Intel HD Graphics 4000

    I am posting here as I'm not techie enough to know if this is definitely a graphics issue.

    For a short while now there have been multicoloured lines, though mostly pink, appearing across the top half of the screen when booting up.

    They are quite random:

    Sometimes there is a narrow band of lines, sometimes a wider band.
    Sometimes it's just one quick flash of lines, another time they appear several times, another time not at all.

    The lines only stay onscreen for a second or two, and always disappear before the login screen appears.

    We have run Dell's SupportAssist to do a thorough check of the laptop, and this is not indicating anything is wrong with the laptop, except the battery.

    I'm looking for advice - as simple to follow as possible please - on how to check this out further.

    Thanks

    :)

    Black line (horizontal) on the screen

    Thanks for replying, actually the problem is a black single horizontal line, not a black screen.

    Dual Screen horizontal lines and tearing.

    Hello All

    I have a dual screen setup, with my desktop extended to a second monitor. A week or so after updating windows 10 with the creators update my dual screen set up is experiencing a large horizontal line traveling up one of my displays with shaking below. I have attached an image.

    This first happened on my primary display (29" Asus connect with display port). After rebooting the tearing then moved over to my secondary display where it has remained for the last week intermittently. (Samsung 22" connected with a VGA to DVI adapter). Both Monitors are connected to my ATI R9 270.

    I have ruled out the display hardware as this issue goes away in safe mode. If I set my computer to only use one display either the 22" or 29", the issue is gone. I have also connected to another computer (mac book pro) and the tearing does not persist.

    Other things I have tried:

    • Reboot
    • Shut down
    • Pulled power cords from monitors and pc for 30 minutes
    • Update graphics card driver
    • Reinstall graphic card driver
    • Try different connectors
    • Uninstall display device in hardware manager

    Any and all help is appreciated as this one is really driving my nuts!

  4. Problem with horizontal lines across screen on boot

    horizontal pink and blue lines

    I have horizontal pink and blue lines starting at the top of my touch screen at start up. The only way to "fix" the problem is to use the touchscreen and restart the computer. I can see a small portion of the desktop at the top of the screen and it appears
    normal. Any suggestions?
