kuvanpäivitysnopeus

Kuvanpäivitysnopeus refers to the refresh rate of a display, indicating how many times per second the image on the screen is redrawn. It is typically measured in Hertz (Hz). A higher refresh rate means the display updates more frequently, resulting in smoother motion and reduced motion blur. For example, a 60 Hz display refreshes the image 60 times per second, while a 120 Hz display refreshes it 120 times per second.

This parameter is particularly important for gaming and fast-paced video content, where a higher kuvanpäivitysnopeus can significantly improve the visual experience. It can lead to more responsive gameplay and a clearer depiction of rapid movements. In general computing tasks, the difference might be less noticeable but can still contribute to a smoother overall feel when scrolling or interacting with graphical elements.

The kuvanpäivitysnopeus of a display is determined by the display hardware itself and the capabilities of the graphics card. While the graphics card can generate frames at a certain rate, the display can only show them at its own refresh rate. If the frame rate generated by the graphics card exceeds the display's refresh rate, some frames may be discarded or displayed inconsistently, leading to screen tearing. Conversely, if the frame rate is lower than the refresh rate, the display will simply show the same frame multiple times until a new one is available. Modern displays often offer adjustable refresh rates, allowing users to select a setting that best suits their needs and the capabilities of their system.
