Cover Image for MacOS: Increase fps on external screen
  • Created at:

Someday I got a trouble with decreased FPS on external screen. It affected on mouse smooth moving. Lags on application responses. The problem was my Mac automatically changed external screen FPS. So, to fix it had to changed FPS back to 60 from set 30. To changed that is quite unclear. You need to do the following steps.

Step 1: Go to "System Preferences", and then go To "Displays" Macos Screen Pref

Step 2: Hold "Alt" and Click on "Scaled" Macos Screen Pref

Step 3: Choose 60 FPS option Macos Screen Pref

After that your mouth should much much faster and lag should go await. Hope it helped you! 😸
