[LCD Monitor] What is TURBO Key?

TURBO key is a one-click step to refresh the overclocking rate and to switch between 60/120/144Hz (for PG278Q) or 60/120/165Hz (for PG279Q) or 60/100Hz (for PG348Q). This eliminates the need to access any complicated graphics driver control panel settings or having to search through the LCD's OSD settings.


 TURBO key is the 4th button on ASUS PG278Q/ PG279Q/ PG348Q monitor.
