Asus swift pg278qr movement shadow

[Mephi00]

Hi,

i just recently bought a Asus pg278qr which i really like, but i do have a minor or major problem:

Everytime something moves on the screen 

it creates a little shadow, for example: the text in my browser leves a white shadow for about 1/2-1 second when scrolling up an down pretty fast.

Is this a problem with my monitor or is it a problem with my setting?(experience would be great)

I‘ve already tried changeing the resolution, refreshrate and the preset setting from Asus helped a little bit but the Capture Point Symbols in BF1 still have a black shadow when moving the camera.
