Why is the UI for certain things SUPER LARGE?

Just got BL2 GOTY on the PC, i am running a Nvidia 960 gtx and 5760x1080 resolution, the main screen is super large and outside of view, shift code same thing, select character screen same thing, how the hell do you fix this ?
I love playing the games in 5760x1080, but it seems this game still doesn’t fully support it, BL2 has been out for years and i am guessing gearbox has no intentions what so ever of fixing this, is there some other 3rd party mod to fix this?
