Windows 10: Grey Horizontal Lines on Screen

I've been having an issue where multiple big lines appear on my screen and flicker randomly when I move my laptop around. I'm on a Lenovo Yoga laptop, running Windows 10. How can I fix this?

Grey Horizontal Line

Since I upgraded my window from Windows 8 to Windows 10, there is a fine grey horizontal line at the bottom of my screen. It's there no matter what I do. It's quite annoying when watching video or movie.

One thing that is funny is that the line is there all the time. However, if I use screen cap, this line does not show on the screen cap though. Any idea?

 

Horizontal grey lines on display

Hi

There's are strange grey lines appearing on a computer when it is connected to a terminal server. The display on the right is from an external monitor, the one on the left ist from the Laptop. When the external display gets turned off, the lines appear on the Laptop's display. However, when the user starts Word directly on the Laptop, there are no lines.

When connections are initiated from other computers or other users, there is no display issue either. Also the lines cannot be seen from another computer via isl light client (remote-support tool).





What irritates me most is the fact that the lines are not completely from left to right but are all intterupted on the white background regardless of the window border or the page layout from the shown Word document. Also that the picture is a screenshot and didn't need to be done with a camera to see the lines is strange after they didn't show up during remote support.

Any suggestions concerning the most probable cause - graphics card failure, driver issue or something else?
Thanks

 

Screen showing grey lines

Thank you for answering. The lines are fine grey lines - some vertical and mostly horizontal covering the entire screen. They last for several seconds but have been lasting longer each time they appear.

It is on a laptop, I have gone to device manager and found the monitor listed and updated, but it said I had the most current version of the driver. What else should I do, that has not helped?

Thanks for any help.
