The fallacy of refresh rates

What is refresh rate? And why is it important?

Refresh rate is the rate in which the TV changes the image. Refresh rates at 60Hz will hold an image of 1/60s. This may leave motion blur if the viewer is able to notice it.


Higher refresh rates along with other aspects can reduce motion blur. Below is a simple illustration.



Most TVs have a refresh rate of 60Hz but due to marketing magic, they are able to quote way higher refresh rates. By using their own modifiers, companies can claim higher refresh rates than their true refresh rates. For example, we found an interesting table from cnet.



In fact, the cnet article can explain this topic better than we can ever do, we highly recommend for you to head over to this website to read up more about refresh rates and the truth behind it.
