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?

Solution 1:

You go to apple menu -> about this mac, and there is a Displays tab with the information.

Solution 2:

You can get the resolution in Terminal using system_profiler by issuing the following command:

system_profiler SPDisplaysDataType | awk '/Resolution/{print $2, $3, $4}'
