Can you please tell me how can I find out the screen resolution and dpi for the screen on my Macbook Pro? (I got it last year, 2009.)

Open the Apple menu at the very top-left of the screen and click on About This Mac. Click on the More Info button, which will open up a window with lots of categories of information. The Graphics/Displays category will tell you your screen resolution.

If you like terminal, then you can get via below command

system_profiler SPDisplaysDataType |grep Resolution

For example

>system_profiler SPDisplaysDataType |grep Resolution
          Resolution: 1920 x 1080 @ 60 Hz

This depends on the model of Macbook Pro (i.e. the screen size - 13.3", 15.4" or 17") you purchased, but the resolution and DPI (or PPI), for the 2009 unibody models, is provided by Wikipedia (here and here).

However, given the resolution and display size, you can easily calculate the PPI. In summary:

MacBook Pro 13.3":  1440x900 (127.68 PPI)
MacBook Pro 15.4":  1440x900 (110.27 PPI)
MacBook Pro 15.4":  1680x1050 (128 PPI)
MacBook Pro 17":    1920x1200 (133.19 PPI)

Open Terminal app and run this command: system_profiler SPDisplaysDataType. You will see output that looks like this:

$ system_profiler SPDisplaysDataType

Or to view and change the resolution: Open the Apple menu at the very top-left of the screen and click on System Preferences..., then Displays. This will show a list of available resolutions with the current one highlighted.

All these answers are good but the fastest way to find the mac resolution is to do SHIFT + COMMAND + 4 (screenshot shortcut). Move the cursor to the bottom right to get the coordinates.

Press SHIFT + COMMAND + 4 with the cursor in the bottom right corner
