Why is 4K at 60 fps important to playing 4K conten

When playing video, “fps” refers to frames per second, also known as frame rate. Each frame is a still image; displaying frames in quick succession creates the illusion of motion or animation. The more frames per second, the smoother the motion appears.

The optimal frame rate for 4K is 60fps; however, some 4K UHD TVs only support 4K at 30fps. This can be a problem because some channel providers, such as Netflix, will only play 4K content if the HDMI® connection with the TV supports 4K at 60fps. You may also find that 4K content is not made available within the channel; for example, the “4K row” may not be displayed in the Netflix channel if Netflix does not detect an HDMI connection capable of playing 4K content at 60fps.
