[2022] AC Valhalla - Borderless shows only on a quarter of the screen.

I have my monitor resolution to 1080p 4x through the NVIDIA control panel and like to use my second monitor while I play so I like to play Valhalla on windows borderless. the whole having to press extra buttons and the game minimizing every time I want to use the other screen isn't worth it. If I set the game to fullscreen, it works perfectly fine and takes the full monitor screen but with borderless, it only shows on a quarter of the screen top left corner. I remember having the same issue with Origins and switched back and forth a few times from borderless, fullscreen and windowed and somehow, I fixed it but it's not working on Valhalla. I know the problem is the game can't recognize that my fullscreen is larger than a quarter of the screen. Is there a way to fix it without me changing the resolution?
