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

If a static image is displayed for an extended period of time, the screen may be damaged and the
image retention can last for a long time or could be permanent. Damage resulting from long-term
static images is not covered by the product warranty.
y
Do not display a static image on the screen for more than two hour. Displaying images in a 4:3 aspect
ratio for an extended period of time may cause image retention around the border of the screen.
