näytetaajuus

Näytetaajuus, often translated as display refresh rate, refers to the number of times per second a display refreshes its image. It is measured in Hertz (Hz), with a higher number indicating a smoother visual experience. For example, a display with a 60Hz refresh rate updates the image 60 times every second, while a 120Hz display refreshes 120 times per second.

The refresh rate plays a crucial role in how fluid motion appears on screen. In fast-paced content such as video games or action movies, a higher refresh rate can significantly reduce motion blur and provide a more immersive experience. This is because the display is updating the image more frequently, allowing for more intermediate frames to be shown.

Different types of displays have varying typical refresh rates. Older monitors and standard televisions often operate at 60Hz. However, modern gaming monitors and high-end televisions commonly offer refresh rates of 120Hz, 144Hz, or even higher. Mobile devices, particularly smartphones, have also increasingly adopted higher refresh rates, with many now featuring 90Hz or 120Hz displays.

While a higher refresh rate generally leads to a smoother image, it also requires more processing power and can consume more energy. The actual benefit of a higher refresh rate also depends on the source content. If the content itself is not being rendered or transmitted at a high frame rate, a high refresh rate display might not provide a noticeable improvement. Adaptive sync technologies like NVIDIA G-Sync and AMD FreeSync aim to synchronize the display's refresh rate with the graphics card's frame rate output, further enhancing smoothness and eliminating screen tearing.
