  1. Horizontal Lines on Desktop Screen after Start-Up


    Hi. My desktop screen is showing some flickering horizontal lines after start-up. It's appearing mostly on the desktop screen and sometimes when watching a video on Youtube when using Google Chrome only. It will disappear after 15-20 mins.I did some RAM and SSD upgrades to my laptop last month. 2 days ago, there was a windows update and my anti-virus software Avast also got updated. I did a System Restore yesterday but that did not solve the problem.Anyone has the solution to this problem? I am posting a photo of the flickering lines so that somebody can help me out with this.Thanks.

    :)

  2. 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?

    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!

    horizontal black line on screen

    Without you having posted a screenshot of it, it may point to either corrupted graphics drivers or a possible failing hardware part.

    We don't know if the horizontal black line is at the top, bottom, middle or where on the screen or the thickness of it or anything else about it.

    Hi

    the line is fine, straight, black, horizontal, black and about 6cm long. It is situated 3cm from the bottom of the screen, and just to the right of centre. I have tried to take a screen shot of it but when I paste to Word it does not appear on the image.
