How to view current display resolution How can I find out the current resolution the screen is running at, in OS X 10.10?

Under settings -> display (which is where I think it used to be), it shows the refresh frequency, but not the resolution.  Using the monitor's controls, I can see it's running at 3840x2160, but how would one find this out from OS X?
You go to apple menu -> about this mac, and there is a Displays tab with the information.
