Sorry not so good english. From Brazil. I have this Macbook: https://support.apple.com/kb/SP653?viewlocale=en_US&locale=en_US
I want a monitor ultrawide49 (3840x1080). For working with coding php/java/python; qliksense; remote ssh with log analysing; docker; jenkins, etc.
I know my macbook only goes officialy to 2560x1600.
I read there are an app called switchresx that maybe unlock the 3840x1080
So I am asking what frequency would it be? Someone here use a similar setup? Please emit your opinion.
