Recently a friend of mine started playing again and wanted to know what resolution I played in windowed mode that fit the screen well without being too small. My monitor is 1920x1080, and I'm pretty sure the game screen resolution I had set in FFXIV config was 17XX by 1XXX.

I went to go check, and that option wasn't available, and lo and behold, now I can't change my resolution back to that setting, so my GUI is screwed up on the next setting higher AND the next setting lower than what I used to have.

With the recent update did they decide to omit certain resolution options?

Is there a way to set it manually via a config file somewhere that I can simply alter in notepad or something like that?

It's not a driver issue, don't even suggest it. I went through a long process of elimination before even deciding to post this here since I don't know what to do or try, short of completely re-installing the game..
