Is it common for dark areas on a plasma television to appear "smudged"....hard to describe but dark areas lose detail and appear a mash of dark colors almost clay like. Does that make sense?
I have never owned a plasma, but I've looked at a lot of them. I have experienced the same thing you describe. They always look like an over-driven CRT to me, with the details often being consumed by what looks like "blooming," even though this technology doesn't have that problem.
I have read dozens of articles about various "new" display technologies and find it very difficult to get excited about plasma displays, especially with the LCD advances of the past few years. The color saturation is about the only thing I personally find interesting, but the expense, fuzziness, life expectancy, burn problems (from network logo "bugs"), weight, and fragility all add up to make them very unattractive to me.
"blooming".....that hits it pretty well. I thought you'd see that on an LCD before you would on a plasma but then I haven't really kept up with plasma tech etc.....seems it is either stunning or blah.
edit: This was on a Samsung - not sure where it falls on the food chain of plasma manufacturing.
