Cannot change resolution properly

I cannot change my resolution properly, if I select full screen and 1920 x 1080 (which my monitor is set to) then the game renders perfectly but refuses to let my mouse go past the first 1280 x 720 pixels, effectively making it useless to use unless I go full keyboard which I won't.
If I change to borderless windowed then it sets to a very low resolution not 1920 x 1080 and cuts off the bottom of the screen.
If changed to custom resolution windowed then I can choose between 1024 and 1280 width and cannot change the 720 height at all. There are preset resolutions up to 1600 x 1200 which isn't helpful either. No screen cutoff with windowed mode unless I choose 1600 x 1200 obviously

I dealt with the low resolution borderless window mode for a few weeks, waiting for a new SSD and a change of OS from windows 10 to 7 that was needed for other things, this hasn't helped ffxiv at all with the problems persisting.

EDIT: found the problem, turning the size of windows up fucks it all up. Won't be turning this off though as straining my eyes is not a valid solution.
