Näyttötaajuus

Näyttötaajuus, also known as refresh rate, refers to the number of times per second a display device updates its image. It is measured in Hertz (Hz). A higher refresh rate means the screen displays more frames per second, resulting in smoother motion and reduced motion blur. For example, a monitor with a 60Hz refresh rate updates the image 60 times every second, while a 120Hz monitor updates it 120 times per second.

The importance of display frequency is particularly evident in applications involving fast-moving visuals, such as video games and high-definition video playback. In gaming, a higher refresh rate allows for more responsive gameplay, as player actions are reflected on screen more quickly. This can provide a competitive advantage and a more immersive experience. Similarly, for video, a higher refresh rate can lead to a more fluid and lifelike viewing experience, especially for action-packed scenes or sports.

Different types of displays have varying typical refresh rates. Standard computer monitors often have refresh rates of 60Hz, 75Hz, or 144Hz. High-end gaming monitors can reach 240Hz or even higher. Television sets also vary, with many modern TVs offering refresh rates of 60Hz or 120Hz, sometimes advertised with terms like "motionflow" or "truemotion" to indicate enhanced motion handling. The panel's actual native refresh rate is the most significant factor, though some displays use interpolation techniques to simulate higher refresh rates. When choosing a display, considering the intended use case and desired visual smoothness is key to selecting an appropriate refresh rate.
