Windows 10: White line in between dual monitor screen

Recently I bought a new PC and connected 2 monitors to it. I noticed that there is a vertical white line at the left hand side of the monitor on the right. It only shows when I am on desktop screen on my monitor on the right, or when I am on the windows on the left monitor.

This occurs every time I on my PC and I am able to solve this by minimizing then maximizing the window usually discord on the left monitor. However, is there any long term solution to this?

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!

 

White Box on screen

The users has a dual screen setup. The scale and layout is at 150% on both screens. The user gets this screen (see below) intermittently on both. The user is unable to interact with that white portion when it appears.

The following troubleshooting steps was performed:

1. Updated Windows and all drivers related to the computer using the website.
2. Changed monitor interface from DVI to VGA for both.
3. Changed scaling to 100% and resolution to 1920 x Y to 1366 x 768
4. Gone into Intel HD Graphics control to Scale full screen
