    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!

    Does anyone have any Ideas? This issue also goes away in safe mode. It also goes away if I mirror my main display with my secondary display.

    That is one of the strangest things I've ever seen.
    I guess I would be contacting the graphics card manufacturer for troubleshooting on that one. Seems like you've tried everything else I can think of. The only other thing would be to put the card in another machine and see if you can replicate the problem.

    If that were true, would the problem not get worse under load?

    Have you contacted the card manufacturer? Perhaps they have a BETA driver which you could try?

    I have tried Beta Drivers with not luck. Since this problem has stated there have been 2 regular updates, which I have applied. Again with no luck.

    Have you tried a clean install? That's about all I can think of.

    Have you used DDU to get rid of all traces of previous drivers before installing the new ones?
