A:Answer Looks like TeamAcer gave you inaccurate information. Sadly the answer is no. You need HDMI 2.1 to hit 120fps. This monitor will do a solid 60k at 1080p via HDMI. In order to hit 120fps, you'd need to hook up this monitor via DisplayPort. With DP you can hit 120fps and beyond, but Series X doesn't support it. The only way to get 120 via HDMI has to be through a HDMI 2.1 port unfortunately. This monitor, and most monitors/tvs nowadays, are 2.0
