I recently upgraded to OS X Mavericks. I have a Mac Pro 13.3 and I use an external Hyundai Monitor 1280 x 768. I would like to set up my external display to 1280 x 768 resolution but the options in Display setting for built-in Display are only 1024 x 768 and 1280 x 960 I can only have optimal usage of my display in mirror mode, but I want to use both displays... is there a possibility to change the values of the built-in display settings? Any one knows how to do so?
