Dual-Mode Performance Capabilities 🚀
The centerpiece of the 27GX790B is its ability to operate in two distinct configurations. The monitor can run at 540Hz while maintaining a 1440p resolution. Alternatively, it can push the refresh rate to an impressive 720Hz, though this requires dropping the resolution to 720p.
LG designed this functionality to accommodate different gaming needs. The high-resolution mode is intended for games where visual clarity is paramount. The ultra-high refresh rate mode is targeted at competitive esports titles where frame rates are the priority.
Switching between these modes is designed to be seamless for the user. The monitor includes a hot key feature that allows instant toggling between the two settings without navigating through complex menus.
