Random Flickering on all my 3 screens

Hellow'

During chrismas, I bought a 2k 144hz monitor, the AOC AGON AG241QX since it has a huge deal.
But since I had this one to my setup, all my 3 screens started having one random flickering every couple of minutes to couple of hours. 
I tried many things, like drivers updates.. vertical sync.. etc etc but nothing change. 
It happens no matter what I do on the computer.. in game, on the desktop.. etc.
If someone have idea that I can try, it would be cool!
(The fact that it flicker on all my screen make me think it's not my new monitor itself. but still..)
Could it be the fact that I use a 144hz monitor with 2 60hz monitors?

 

My setup:
i7 7700k
EVGA 1080ti FTW3    (Didn't had the money for a G-Sync monitor)

Asus Strix Z270F

Corsair Vengeance LPX DDR4-2133 (2x8)

 

Monitor:

AOC AGON AG241QX   (1440p/144Hz)   x1  (center one)   (DisplayPort)

Samsung S24D390HL    (1080p/60Hz)     x2  (side ones)   (HDMI to DisplayPort)

Thanks guys!
