Scan line problem

[JcGross]

Lately I've noticed that there's a can line going down my screen constantly. I don't know weather it's the graphics card or the monitor, I'm curious weather anyone else has any experience with this or if anyone knows what can cause this. Both my graphics card and my monitor are still covered by warranty so I'm good either way. I made a video for demonstration purposes but it isn't very noticeable on it, but trust me, it's horrible irl. If anyone doesn't know what I'm talking about, it's like vertical tearing in games, but it's constantly present and it's running down on the screen and when reaches the borrom it starts again from the top. I've tried to set the desktop refresh rate lower but it didn't help.

That's strange. 

I suppose the only thing  you can do is try the monitor on a second source and see if the problem is the monitor or your pc.

if its your pc i would Guinness drivers then the gpu

Guiness drivers? I've never heard that expression. Thanks for the reply though, I figured that I would change up the monitors with the other PC, see if the problem persists.
