Display Modes and Refresh Rates
The AGP277KXM offers a dual-mode function that allows users to prioritize either resolution or speed. In main mode, the monitor supports a 5K resolution of 5120 x 2880 at a refresh rate of up to 180 Hz, which corresponds to a pixel density of approximately 218 PPI. Alternatively, the display can be switched to a QHD resolution of 2560 x 1440, which increases the maximum refresh rate to 360 Hz.
