Does this have a higher refresh than 60 hz? It says 60 but details it says it can got 100+?
Answered by LG Digital Customer CareHi 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. https://www.bestbuy.com/product/lg-27-4k-3840x2160-uhd-ultrafine-borderless-design-pc-monitor-27us550-w-white/BGTKK8P3F7 If you have any further questions about its features, please contact us on lgdigitalcare@lg.sprinklrsupport.com, and our team will be more than happy to assist you. —Renzo
