He probably is that is the funny thing about it all. Apple is afraid that number might scare us so all we now get is this:
(edit: sorry about the large image I just grabbed it from Apple)
Yes seriously that is the resolution setup now. To actually set the resolution like on windows or linux you need 3rd party software.
To make it perfect it actually tell you what it looks like but technically is not. My screen is 2880x1800 but MacOS tells me largest resolution "looks like 1920x1200". The OS is just faking it with GUI size etc. and looking at say images it is fairly obvious that it is definitely running 2880x1800.
You can find what resolution your screen is in "about this Mac" found by clicking the apply icon in the top left corner. That will give you the overview screen telling you what version your Mac is. The second tab "displays" should mention resolution. If for some reason not you should at least be able to find what version you got or what the name of your monitor is which should also help in determining your screen resolution.
