Windows 10: A white vertical line on the edge of a dual monitor setup

Hi,

I recently upgraded my setup and bought an NVIDIA graphics card all the latest drivers are installed, which I hooked up to my dual monitors.

Sometimes, when I'm using a program on the main monitor, a white vertical line only a couple of pixels wide appears on the edge of the second monitor. However, when I click again on the program running on the second monitor, the line disappears... very strange. It only happens sometimes, but it freaks me out.

I'd appreciate any help possible.

By the way, both monitors are Dell P2319H, running with the same resolution. The machine is running Windows 10 Pro OS build 19042.804.

Thanks in advance,

Tomer

Hi Yuri,

• Press Windows key + X and select Device Manager.
• Expand Display Adapters.
• Right click on the driver and select Update Driver Software.
• Follow the on-screen prompts to update the driver.

White vertical lines on Nokia 7610 Display

My friend has Nokia 7610, and its display has vertical white lines. I changed its theme but no change. Can anybody help as how to rectify this problem. Should I format the phone to remove these fade vertical lines from the display. Is it because of some
hradware problem or could it be a software problem?
