Paul,

I don't know about 220K filters. But then again, I haven't found that HDTVs in the stores are clearer, especially if you are comparing similar content. For example, when I go into a big box store and look at live broadcast TV, it often looks worse than what the same broadcast would look like at home.

Now if you are comparing a playback of a Blu-ray disc in the store to a regular DVD at home, then the store could easily look better.

Also stores have a tendency to set up their TVs to be overly vivid and sharp, that may be what you are seeing.

Am I hitting any possibilities?
