ISM (Image Sticking Minimization) Method

-A frozen still picture from a PC/video game displayed on the screen for prolonged periods will result in a ghost image remaining even when you change the image. Avoid allowing a fixed image to remain on the TV's screen for a long period of time.

1.Press the MENU button and then use D / E button to select the SPECIAL menu.

2.Press the G button and then use D / E button to select ISM Method.

3.Press the G button and then use D / E button to select either Normal, White wash, Orbiter or Inversion.

Normal

If image sticking is never a problem, ISM is not necessary - set to Normal.

White wash

White Wash removes permanent images from the screen. Note: An excessive permanent image may be impossible to clear entirely with White Wash. To return to normal viewing, press any button.

Orbiter

Orbiter may help prevent ghost images. However, it is best not to allow any fixed image to remain on the screen. To avoid a permanent image on the screen, the image will move every 2 minutes: Right Right Downside Downside Left Left Upside Upside.

Inversion

Inversion will automatically invert the TV panel color every 30 minutes.
