Using ISM Method
Displaying a static image on the screen for a prolonged period of time could result in burn-in or image
sticking. To avoid burn-in or image sticking or to fix a ghost or burned-in image, do not display a fixed
image for prolonged periods of time. Either turn the display off or change the image. If you display a
static image for long periods of time, you can help to avoid ghost images or burn-in by using the ISM
option as follows:
1. Press the MENU button, and then use the down arrow ▼ or up arrow ▲ button to select the
OPTION menu.
2. Press the right arrow ► button, and then use the down arrow ▼ or up arrow ▲ button to select
the ISM Method menu.
3. Select one of the following menu options:
● Normal—Leave on Normal if you do not want the ISM function to be active. When the
display is turned OFF, the ISM setting will be reset to Normal, regardless of which ISM
mode was ON when the display was turned off.
● Orbiter—The screen will move two pixels every two minutes, alternately moving left, right,
up, and down. Orbiter will remain on until changed in the ISM menu.
● Inversion—This function can be used to fix a ghost or burned-in image. This function will
invert the image colors every 30 minutes. If the screen image is inverted and you enter the
USB function, images displayed in this function will be inverted. The inversion function will
remain on until changed in the ISM menu.
● White wash—This function can also be used to fix a ghost or burned-in image. This
function will fill the screen with solid white. This helps to remove permanent images burned
into the screen. Pressing any key on the remote control will exit the White Wash function
and return the screen to Normal.
Using Tile Mode
Tile Mode is used to extend an image across multiple displays in a video wall. You can define up to a
5 x 5 video wall and the displays can be in either landscape or portrait orientation. Tile Mode allows
you to assign each display its relative position (number) in the wall starting at the upper-left corner and
down each row from left to right. Each display will automatically show the corresponding part of the
full image as shown in the following figure.
Assign the correct position number to each display as follows:
MENU→PICTURE→TILE→Tile Mode→OK→3x3→Close→Tile ID→OK→1 (for display #1, 2 for
display #2, etc. ... 9 for display #9)→Close→Natural Mode→OK→ON (compensate for the
mullions to display an image without distortion across the video wall)→OK→EXIT
