Hello there,
Thank you very much for your interest in our Ultra HD HDMI Cable. Regarding your question about the refresh rate I wanted you to know that this model is designed to work with the max speed allowed by the HDMI standard, so it will support any refresh rate that can be passed thorugh HDMI from the source.
I hope you enjoy this and other Dynex products.
