"A refresh rate, sometimes also referred to as frame rate, refers to how many times a TV screen shows an image per second. Measured in hertz, there is a very complicated formula that electrical engineers use to calculate refresh rates, but it's easier to imagine your TV as a very fancy slideshow projector with each frame as a separate still image."
"Even the most basic modern television will have a base refresh rate of 60Hz, which is the same as ancient cathode ray tube models. But modern TVs are capable of producing 4K images that are densely packed with visual information, whereas the old CRT models maxed out at 480p with vastly inferior contrast and color accuracy."
Refresh rate, measured in hertz, indicates how many images a TV displays per second. Modern TVs typically start at 60Hz, which is sufficient for general viewing. Higher refresh rates enhance picture quality, especially for fast-moving content like sports and gaming. As technology advances, many smart TVs now offer refresh rates comparable to high-end gaming monitors. Choosing the right refresh rate depends on individual viewing preferences and the type of content consumed.
