What is a refresh rate on a TV?
A TV’s refresh rate is how many times the screen refreshes itself every second. It’s different from frames per second (fps), which defines how many frames the video source displays every second. The refresh rate is important for motion handling, as a higher refresh rate generally results in smoother motion, but it’s not always the case.
What is the difference between refresh rate and frame rate?
The refresh rate is often confused with the frame rate (fps or frames per second). They are indeed very similar, and both refer to the number of times a static image is displayed per second, but the frame rate usually refers to the content itself, whereas the refresh rate refers to the video signal or display.
What is effective refresh rate and clear action?
Vizio Effective Refresh Rate and Clear Action (2018) While Vizio still uses confusing terminology to describe the refresh rate of their TVs, the numbers are easier to translate now than they used to be.

What is the refresh rate from different sources?
Different Refresh Rate From Different Sources Content Frame Rate Netflix 24 fps to 60 fps Amazon Video 24 fps to 60 fps Blu-ray movies 24 fps YouTube 30 or 60 fps
By flashing a series of still images, the TV (just like film or animation) creates the illusion of motion. The refresh rate is measured in hertz (named after physicist Heinrich Hertz, who did groundbreaking work on electromagnetism). So if a refresh rate is 120 Hz, it means that the image is refreshed 120 times per second.
What is the refresh rate of Sony’s 4K TVs?
And Sony refers to its 4K TVs as offering “Motionflow XR 960,” but in both cases, the panels only have a native refresh rate of 120 Hz. The rest is clever video processing.
How does an HDTV’s refresh rate affect the frame rate?
Once an HDTV’s refresh rate goes above the rate of the content you’re watching, it starts performing tricks to produce a higher frame rate.
What does 60 FPS look like on a 120Hz TV?
A 60 fps video played on a 120Hz TV should look almost identical to the same content played on a 60Hz TV. In a case like this, the TV either adjusts itself to match the refresh rate of the source, which effectively turns it into a 60Hz TV, or it simply doubles every frame. 60 fps content played on 60Hz TV (TCL 4 Series/S425 2019)
