Screen issue.

[Callos]

This probably has to do with your monitor. Because the green line problem seems like the screen is not in-tune with your video card.
There's nothing wrong with the video, haha.
Here's a checklist, with a few possible fixes.

- Are the cables plugged in correctly and do they fit tightly into the computer/screen?
- Are you using 3D mode for some reason? If so turn it off.
- Did the monitor come with a driver you needed to install?
- Do you have to minimum video card requirements to use the monitor?
- If so, is your video card driver up to date?
- Is your computer configured to display on that screen and is it recognized as a PC screen in the configuration?
- Have you tried fiddling around with the options on the monitor?
- Is your monitor on 50Hz? Set it to 60.

If problem still persists, PM me with a DxDiag (Go to Home Button -> Run... or type in search bar -> type dxdiag and hit enter -> Save All files -> Save it to a location -> Open the txt file and copy the text)
and a full model number/ID/name/product information of your monitor.

Thank you very much for the help!
I will try these things soon, I asked my brother who studies computer science,
he said it was called ghosting and probably because of a dodgy unit I got.
Thank you!
