A:AnswerHDMI 2.0 can get it up to like 120hz but get a DisplayPort cable no HDMI if you are trynna get the best frame rate. Make sure the computer can handle the 240 hz or you are wasting money if it can handle it make sure you know how to turn on the the g-sync setting on the nvdia control panel and make sure you set the monitor to 240 refresh rate on the computer I forgot and was playing at 60hz for like 2 weeks.
