Ghost Image Appears on the Screen

After-image appears when the set is turned off.

If you display a fixed image for a long time, the pixels may be damaged quickly. Use the screen-saver function.

Note

Vertical frequency: To enable the user to watch the set, the screen image should be changed tens of times every second like a fluorescent lamp. The vertical frequency or refresh rate is the times per second the image changes. The unit is Hz.

Horizontal frequency: The horizontal interval is the time to display one vertical line. When 1 is divided by the horizontal interval, the number of horizontal lines displayed every second can be tabulated as the horizontal frequency. The unit is kHz.
