kuvanpäivitystaajuuden

Kuvanpäivitystaajuus, often referred to as refresh rate, is a fundamental characteristic of displays such as monitors and televisions. It quantifies how many times per second the image on the screen is redrawn or refreshed. This is measured in Hertz (Hz), where 1 Hz signifies one refresh cycle per second. A higher refresh rate means that the image is updated more frequently, resulting in smoother motion and a reduction in perceived flicker, especially during fast-paced visual content like video games or action movies.

For instance, a display with a 60 Hz refresh rate redraws the image 60 times every second. In contrast, a display with a 120 Hz refresh rate redraws the image 120 times per second, offering a noticeably smoother visual experience. The impact of refresh rate is particularly evident when comparing standard refresh rates (like 60 Hz) to higher ones. While a standard refresh rate is sufficient for many everyday tasks such as browsing the web or word processing, a higher refresh rate is highly beneficial for gaming and other applications where fluid motion is critical for optimal performance and user experience. Manufacturers often highlight refresh rate as a key specification when marketing displays, as it directly influences the perceived quality of motion on the screen.
