I'm having a g-sync issue neither nvidia nor windows support could help me

hello everyone, im having this issue since i bought the laptop

here is a link to show u the exact problem other ppl had it too

https://forums.playbattlegrounds.co...see-red-green-and-sometimes-blue-fuzzy-lines/

when enabling g-sync it happens in almost every game but when its off it never does happen and if g-sync was enabled and the game was in windowed mode it doesnt appear.

so what did i do to try and fix this ?

1- reinstalled windows
2- DDU safe mode unistalled the reinstalled nvidia
3- i was overclocking the screen to 103hz but i did reset it to 75hz to see if overclocking was issue but not

I guess thats about it , nvidia said its a faulty gpu, if it was faulty why does it work flawlessly in games without g-sync ? i have the gpu undervolted to 0.800 and clocked at 1670mhz, doesnt even reach 65c

laptop model Acer predator 17 x

CPU 7820hk
GPU 1080 GTX
Ram 32GB 2400mhz
SSD 1TB
HDD 1TB

plz help me to figure out what is the issue here

Regards,

 

Have you tested without the voltage curve applied?

 

I have tried it at stock settings and it still the same issue.
