How to identify ghosting?

[KindaHardcoreGamer]

I think I may be experiencing ghosting/blurring on my 4ms monitor, but I want to rule out other things first. Is it possible to mistake frames for ghosting, or no? I'm not sure.
Also, how much is too much if it is there?

This is an example of ghosting:

Is this what your problem looks like.

Was that a picture(like from a phone) or a screen capture. ghosting is an issue on the monitor(not on the actual gpu) so a screen capture wouldn't pick it up.
