I recently purcahsed this set at my local Best Buy. This is my first plasma set . I was planning on getting a 46" LCD but jumped for a plasma because it was a bigger screen for the same price. However , i am not so pleased with the performance of the plasma. Whenever there is a bright white area displayed anywhere on the screen, it casts a dark shadow to the left an right of it. If there is a dark object anywhere near something white, it creates a black shadow and it will move with the object. Also happens when i play Xbox 360 when i select something on a menu and it becomes highlighted, there is a dark band that goes all the way arcross the screen. Is this normal for a plasma set to do? Is mine defective? I have tried adjusting my settings but nothing has helped.
