Cables are not a cheap monitor, what could be the problem?

Question

Monitors

I recently purchased an LG 27GL850 monitor. I noticed that when the picture moves on the monitor, there is a barely noticeable trail from it. This is especially noticeable when the borders of the movable object are black (for example, scrolling black text on a white background, in a game with a calimator sight, when turning sharply, the dot turns into a strip). The monitor is connected via DisplayPort 1.4. gtx 1080ti video card How can I solve this problem? there is one cant in the computer is a 650 watt power supply
