Ruudunpäivitystahti

Ruudunpäivitystahti, often referred to as refresh rate, is a technical specification that indicates how many times per second a display refreshes its image. It is measured in Hertz (Hz). A higher refresh rate means that the display updates the image more frequently, resulting in smoother motion and a more fluid visual experience. For example, a display with a 60Hz refresh rate updates the image 60 times every second, while a 120Hz display updates it 120 times per second.

The impact of refresh rate is most noticeable in fast-paced content such as video games, action movies, and scrolling through web pages or documents. A higher refresh rate can reduce motion blur and screen tearing, making fast-moving objects appear sharper and transitions smoother. This is particularly important for gamers, where a higher refresh rate can provide a competitive advantage by allowing them to react more quickly to on-screen events.

Different types of displays have varying typical refresh rates. Standard computer monitors often have refresh rates of 60Hz or 75Hz, but gaming monitors commonly offer 120Hz, 144Hz, or even higher. High-end televisions also increasingly feature higher refresh rates to improve the viewing experience for sports and movies. While a higher refresh rate generally leads to a better visual experience, it also requires more processing power and can consume more energy. The optimal refresh rate often depends on the intended use of the display and the capabilities of the connected device.
