    I have a 15" rMBP (Mid 2012) running Mavericks. In addition to he built-in Retina display, I mirror to an external Dell U2410 Display/Monitor connected via a Monoprice "Min DisplayPort + UB to Dual-Link DVI Adapter." To my old eyes, I see no difference in image quality between the two screens, yet the internal monitor is set for "Best Retina."

    How can I determine what resolution I am getting on each screen? I'm still new to Apple, so I will appreciate detail in your reply.

    Thank You.

    System Preferences → Display.

    Two separate windows should pop up, one for your Dell and one for your retina.

    I see only one Window under the Displays tab and it says "Best for Retina". So how can I tell what resolution is actually appearing on each screen?

    I don't see any resolution settings for my rMBP or my Apple Cinema Display. For both I have Best for display or Scaled.

    Prior versions of OSX had the actual resolution, no more at least for Apple displays.

    Just click 'Scaled' and then you can see.
