Blade 17 + DyAc Monitor

Hello.
Trying to connect my blade 17 2080 maxq super 300hz (2020) to a Zowie XL2546 Monitor..
Got the thunderbolt 3 to display port cable from ebay, but something is not right ...
i can't get DyAc to work..
For example, when i ADS in Warzone image is quite blurry and i can't track anything ...
I did everything i could software wise and nothing helped, and i came to the conclusion that the issue is in my cable..
Does anybody run same setup?what cable should i use for this?
Please post some links to where i can buy one .
Thank you
