A stunning problem with plasma displays is low bit depth. While they have deep blacks if you look at gradated images, such as a street light at night , you see very distinct stair steps.

Many sets get by with the fact most people don't pay attention and most images are to busy for it to be readily spotted. There is also the habit for plasmas ,and cheaper lcds, to add noise to the image to break up such smooth gradients.

If you drive your TV with a computer it really stands out. It's not a limitation of plasma, the sets can produce smooth gradients they would just have to be more expensive.
