How to change screen resolution in Mac

Here are the steps to get this done:

  1. Open the System Preferences (either from the Dock or from the Apple menu).  
  2. Go to the Display Panel and choose the 'Display' tab.
  3. On the left of the Displays tab you can select one of the Resolutions from the list. Higher resolutions allow you to see more “stuff”. IT is recommending at least 1024x768 unless you have a specific reason to use a lower resolution. 
  4. Quit or close the System Preferences when done.
Also make sure:
  • At higher resolutions, you may not be able to see as many colors (Thousands instead of Millions)
  • Flat panel monitors have a prefered resolution. If you set the display lower or higher, the display will be noticably more blurry. The prefered resolution should be noted in your display manual. For example, the new 17 inch Apple Studio Display (flat panel) is most crisp at 1280x1024.
