It takes a while for the picture to appear. | The unit digitally processes the various signals in order to reproduce esthetically pleasing | ||

|
|
| Do not allow a still picture to be displayed for an extended period, as this can cause a permanent |
|

| image retention to remain on the Plasma Display. |
|
|
| Examples of still pictures include logos, video games, computer images, teletext and images |
