[JackRob]

Hello everyone, i have looked everywhere for found an easy way to fix my problem (and tried maaany possible solutions) but without any results.
So i need your help, i have an ultrawide LG monitor but i can't use the max resolution (2560x1080).
Furthermore Sierra (10.12.6) recognizes in wrong way the Gpu.

I implore yours help, i don't know where to look..

P.S. I'm 16 years old and write from Italy, sorry for my english
