When a computer loses its picture, a green line and grainy image appear on its screen. It’s no big deal. The green line is the result of a bad display cable that needs replacing. The grainy image is the result of a faulty graphics card and/or bad video cables. Some of these symptoms may be vague, and left unstubborn, the solution to the problem may be a mystery.
The color of your monitor/display can be off at times, and it is actually quite a visible problem. This is mostly due to the different color outputs from the digital signal processing (DSP) chips on your monitor. The DSP chips are responsible for the image display on your monitor, and they produce a color signal for the monitor to use in producing the video signal.
When PC monitors or their attached displays fail to operate correctly, there are several possible causes. One of the more common causes is the presence of interlaced (or partially interlaced) video, which is a form of video in which each frame is split into two sub-frames.

Computer displays, like all other components of a computer system, are affected by a variety of variables, including computer input, monitor settings, and monitor performance. One or more of these things may be to blame if you notice vertical lines on your screen. Fixing vertical lines is sometimes simple, and other times it requires some troubleshooting.
What produces the pink and green lines on the screen of a Windows computer?
Horizontal or vertical lines on your computer screen may be caused by a number of issues, ranging from outdated video card drivers to broken ribbon cables and incorrect video cable connections. You may check the BIOS settings to see whether the issue is software or hardware.
Because the BIOS is not included in Windows 10, if you still see horizontal or vertical lines on your computer screen, it is a software issue. It’s a hardware issue if you don’t see horizontal or vertical lines on your Windows 10 computer screen.
