Faint static images are visible
regardless of content being played
If a static image is displayed for a long time, the pixels may be damaged. Use
the screen-saverfunction to prevent this.
When a dark image is displayed on the screen after an image with high contrast
(black and white or gray), this may cause image sticking. This is normal for LCD
screen products.
