As seen in picture, and no, those aren't the kind of lines when you take pictures of a screen a certain way. I have 3 monitors and all are fine except for this one, which goes through displayport to VGA adapter (the others are HDMI and DVI active to VGA). This happens with two different displayport to VGA adapters and two different VGA cables, can anyone else me with this?

I assume you're describing the alternating light/dark striations or banding across the screen? Since you say running down the monitor, does that mean they move down the screen like ripples? If so, then it's probably a fault in the power supply board, or if that monitor uses an external power brick, in that.

Either way such a fault would be likely to be bad electrolytic capacitors, but since an external power brick can't generally be opened up, a replacement PSU would probably solve the problem. If the mains goes straight into the monitor, then often replacement of the capacitors on the PSU board isn't too difficult to do.
