What is 600Hz?

Plasma TV specifications hype “600Hz” refresh; is this better than 120Hz or 240Hz?

If you read my “What is refresh rate?” post, you’ll know that plasma TV manufacturers (Panasonic, Samsung, and LG) make a point in claiming a “600Hz” refresh rate on their TVs. As we discussed in that article, it’s not exactly comparable to LCD’s 120 and 240Hz refresh.

So what is 600Hz, and how does it work?
