What is the advantage of a 120Hz refresh rate versus a 60Hz refresh rate for a display?

I’ve looked at two displays side by side with the same 1080p resolution, but one had a 60Hz refresh rate and one had a 120Hz refresh rate. I couldn’t tell the difference, to be honest. When does the faster refresh rate become a noticeable advantage?

What Is the Difference Between 60Hz & 120Hz HD LCD TVs?

"Whether a 120Hz refresh rate is better than 60Hz is a matter of debate. The difference is most noticeable with fast action, such as live sports and films viewed in high definition. For non-HD broadcasts, a 60Hz image can be perfectly suitable.

As consumers became more familiar with HDTV technical terminology, manufacturers looked for features they could market as innovative or as distinctive. As HDTVs with 1080p resolution became the sets of choice, manufacturers began marketing the refresh rate and promoting 120Hz."


I disagree a little with the article Christopher cited. Rapidly moving images can “tear” or look blurred at 60Hz. Most of the time, I only notice it when watching a hockey or football game in HD, and the camera pans rapidly. 99% of the time, you probably won't notice the difference, but it can be distracting when you do. 


A faster refresh rate doesn't really matter, according to this article. Here's the bottom line:


"First, you can't add detail beyond what is already in the source footage. Second, the source footage is never greater than 60Hz."


There's more detail in the article. It's pretty interesting.
