Because of the phenomenon known from times of the crt as the degradation of the phosphor, it is not always completely. Especially on the first-generation model. Phosphor in these areas remained more 'fresh' in long-term view images 3×4. If you then turn on wide picture, it was possible to observe higher brightness at the edges of the picture.

Nevertheless, there remains the problem of uneven brightness reduction across the screen. Producers are struggling with this in different ways, however, it is difficult to recommend a plasma to display static images. The budget model, you need to listen carefully to the graininess – should carefully examine the picture on the screen from such a distance with which you want to watch tv at home.
