macOS does not require display drivers when using a ViewSonic Display. The macOS operating system will automatically read the EDID information stored in the monitor and use the system information/profiler utility to detect the monitor’s specifications and capabilities.


Here is a list of factors that may limit you from running the monitor at optimal performance: 

  • Graphics card drivers 
  • Video cable adapters 
  • Docking stations 



To ensure you are running the latest display drivers on your MacOS device: 


1. On your Mac, choose Apple menu and select System Preferences.


2. Once System Preferences opens, select Software Update.


3. Your computer will automatically scan and prompt you if a system update is required. Close the window once the update has completed.




To ensure you are running the optimal resolution: 


1. On your Mac, choose Apple menu and select System Preferences.

2. Once System Preferences opens, select Displays.



3. If the “Default for Display” option is not providing the most optimal resolution, press and hold the Option button on your keyboard while you click Scaled to see additional resolutions for the second display.


4.  Now, you should be able to select the optimal resolution.
