AW2518H, GTX 1070 Ti, pixels pattern during gaming

I have a bad experience with this AW2518H so far.

I play PUBG and Overwatch, and I can visually see the net of the pixels while moving with my character (I am sitting 2 feet from screen which is far enough for a 24" screen).

It's very ugly and ruin my experience of playing games, this is very noticeable on a white surfaces. I am running on normal response settings. Do you have any idea how can I fix that issue so i can see a clear picture and not a net of pixels?

Updates on what I've tried so far:

1) get latest Nvidia drivers

2) install monitor drivers

3) set response time to normal fast or very fast

4) change colors

5) change to HDMI cable

Nothing fixed this issue.
