Amazon Panasonic TV warning - g20

Amazon are currently selling the Panasonic L32g20 LCD tv set on their site. They quote it as having a 200hz refresh rate when it's only 100hz.

This is a pretty big deal and I've had a lot of people at work asking me if we stock the 200hz 32" panasonic. Turns out we do, except it's not 200hz.

If you're buying the TV thinking you're getting an amazing deal, you'll be sorely disappointed. It's still a really good TV, but you're only getting half the spec you'd be expecting.

It's not interlaced, is it? I know that interlacing would require 200Hz refresh rate to get the equivalent of 100Hz, but that usually applies to tube TVs.

AFAIK as LCD screens are progressive, it doesn't work quite the same way CRTs did. What these TVs do is turn 50 screen refreshes into 100, and in the extra frames, they interpolate the motion on the screen to reduce motion blur.

For example. If the TV's fields on a 50hz screen were numbered 1, 2 and 3, a 100hz panny, sony or samsung set would number them:

1, 1a, 2, 2a, 3

1a and 2a would be fields created by the tv that were effectively guessing what happened between 1 and 2.

I find it really hard to explain .

But either way, a 200hz screen does it twice as much.
