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
