60Hz or 120Hz for Sport? Understand Refresh Rate
Panel refreshes per second do not automatically equal the number of original frames in a broadcast.
A 60Hz panel refreshes 60 times per second; a 120Hz panel refreshes 120 times. Video frame rate describes the images supplied by the source each second. Sony distinguishes these measurements. Confusing them can create expectations of motion information that never reached the television.
What does the broadcast supply?
A 60fps video sent to a 120Hz panel does not contain 120 different original frames per second. The display's presentation and processing determine how it uses those additional refresh cycles. Supported input formats are also different from a marketing number attached to a motion feature.
Look for native refresh rate in the specifications, then check the input rates supported at your intended resolution. A sports preset or a large number beside a motion-processing name does not establish either specification.
Compare moving pictures
Watch a horizontal camera pan and follow the ball, player outlines and fixed onscreen text. Compare the current motion setting with a gentler one while keeping the rest of the picture unchanged. Samsung documents several motion controls, but names and adjustment options vary by model.
Describe what bothers you: regular judder, blur or distortion around moving objects. These are different observations, and the Hz figure alone does not explain them.
Use the comparison when buying
Ask to see material similar to your usual broadcasts from a realistic distance. Assess movement alongside brightness, viewing angle and source quality. Do not reject a satisfactory 60Hz television merely because of its number, or assume every 120Hz model performs identically. Base the choice on the particular display and source you will use.
