A:Answer Hi Joe, at the risk of oversimplifying, content (gaming consoles, cable providers, streaming services, etc.) measure in FPS, and hardware (TV's monitors, etc.) is measured in Hz. They are a little different, but this TV can support 4K content at 60Hz (FPS depending on which side of the HDMI you're on) without compression. It is also the most affordable 120Hz (240 motion rate) TV in Samsung's lineup. If you are looking for something more fully featured try our Q70T and above for more thorough HDMI 2.1 support. ^Scott
