I can't seem to make the aspect ratio fit the full OBS screen at 1920X1080. The aspect ratio seems to be stuck a t a large 4:3 frame and it wont change please help

That's a problem with your capture card's settings, not obs'

 

[Captfalcon]

so how would fix it through my capture device?

In the properties and/or configure video settings of the source.
