, Appendix }
The vkJeo program that you watch may be high definition (HD) or standard definition (SD), This Plasma Display is designed to scale
to each type of definition properly, If the video program's definition type changes while a menu window is displayed on the screen
(for example: HD_SD or SD_HD), the menu size may temporarily shrink or enlarge until the scaling is completed, This may
happen, for example, when you switch between television and an external digital video recorder (D-VHS), or when your recorded
program switches between different definition types, while the on-screen menu is being shown,
If this happens, the menu will return to its normal size after two to three seconds, This action is normal, and does not indicate a
problem with your Plasma Display system,
