A:Answer Hi there, Sam. Thank you for your inquiry regarding the LG UHD Monitor, model 27US550-W. We understand you are seeking clarification on the refresh rate capabilities of this unit.
According to the official specifications, this monitor has a native refresh rate of 60Hz. It does not support a refresh rate of 100Hz or higher. The reference to "100" you may have seen likely refers to the Power Input requirement (100~240V), rather than the display speed.
