Dramatic with CRT models
Some also exhibit noticeable hot spotting–greater brightness at the center of the screen than at the edges or corners–though this is less of a problem than it used to be. All RPTVs exhibit some falloff in image brightness as you move away from directly in front of them, either horizontally or vertically, but this effect is generally most dramatic with CRT models. But you can minimize the risk of burn-in by using reasonable refurbished lcd tv contrast and brightness settings–which almost always means turning down the controls from their typically overzealous factory settings. In severe cases, the result can be faint but permanent ghost images. Another issue with CRTs is that they are subject to image burn-in.
