A:Answer For this 75 inch TV, the HDMI ports can support up to 4K/60Hz. However, this TV does feature Game Accelerator 120 and Motion Rate 240 with MEMC Frame Insertion which combines multiple motion enhancement technologies for best-in-class motion clarity. Our larger 85 and 98 inch Q651G, as well as our QM751G and QM851G can support 120Hz. Hope this helps! Thank you, TCL Customer Support
