What is the refresh rate and why is it important?

The refresh rate indicates the number of times that the image refreshes every second. For example, a PC monitor has a refresh rate of 72 Hertz (Hz) and therefore refresh all the pixels of the screen, from top to bottom, 72 times every second. The refresh rate is fundamental because it determines the image's quality: if it is too low, the human eye can see a flicker that causes headaches and can damage eyes. To provide a comparison, most of the TV monitors have a refresh rate of 50Hz and only few products of the last generation have a 100Hz refresh rate. Lightking Screens - screens have a 300 Hz refresh rate, which is almost triple of the most advanced cathode tube technologies. This measure is ulterior prove of Lightking Screens quality and state-of-the-art technology, a result of years of research in laboratories and in the field.
