How to Change Resolution for External Monitor on Mac: 3 Simple Methods

Method 1: Adjusting the Display Scaling for External Monitors

For those who prefer not to use third-party applications, you can easily adjust your display settings by following these straightforward steps.

Step 1: Click on the Apple icon located in the upper-left corner, then go to System Preferences > Displays.

Step 2: Examine the connected display listed at the top and review the resolution options available.

Resolution Adjustment for Mac External Display

Here are the resolution selections for our 4K Samsung M7 monitor when it is connected to a 14-inch MacBook M1 Pro:

  • 1920 x 1080
  • 2560 x 1440
  • 3008 x 1692
  • 3360 x 1890
  • 3840 x 2160

Keep in mind that as the resolution increases, the system text size reduces. Even with options like QHD or Full-HD, macOS intelligently scales it to accommodate your monitor’s resolution. For instance, when we connected a 4K display to our MacBook and selected 2560 x 1440 in the system settings, the system seamlessly adapted it to 4K resolution.

To explore all available resolution options, scroll down and select Advanced within the same settings menu. Enable the ‘Show resolutions as list‘ option to view all choices.

In addition to adjusting display resolution, you can modify the following settings from the Displays menu:

  • Color Profile: Select from various color profiles such as Adobe RGB, Display P3, and more. Advanced users can create a custom color profile on their Mac.
  • Refresh Rate: If you utilize a high-refresh-rate monitor, adjust the refresh rate settings here.
  • High Dynamic Range (HDR)
  • Rotation

Method 2: Using BetterDisplay for Enhanced Display Options

The display settings within Mac preferences are relatively basic. To access more advanced display customization options, consider using third-party software like BetterDisplay.

Step 1: After downloading BetterDisplay and granting it the necessary Accessibility permissions, open Accessibility Settings and toggle the switch next to BetterDisplay.
