21:9 ratio suddenly gone in options

Ive been playing diablo again after a long while and first couple days the game automatically recognized my monitor and had a 21:9 (2580x1080) resolution available for me to choose. Now i open up the game and idk why its not there. I try running the game through NVIDIA Experience but nothing works. I know its not a big issue but it bugs me how i cant truly utilize my monitor. Any comment helps.

Hey, JayyChris3!

Please try to delete the Documents/Diablo III/D3Prefs.txt file and default your Nvidia settings.
