Power On Delay

Power on delay lets you stagger the initial current draw of multiple displays on one electrical circuit. Each display will compute its own delay time. If its V Monitors setting in the Tiling submenu is 1, the delay will be a random number between 0.5 and 2.5 seconds. If V Monitors is anything else, its delay will be (0.5 * V Position) seconds.

Using Key Lock

The buttons on the back of the panel can be disabled to prevent accidental changing of the settings. To do this, press the left and right arrows buttons simultaneously and hold for 5 seconds. The same procedure will enable the buttons again. If the buttons are not accessible, use the infrared remote control to enter the OSD menu, navigate to the Option 2 submenu, and turn the Key Lock option off or on.

Setting the backlight level

The OSD offers two setting which change the backlight level. The Backlight setting is a scale from 0 to 100. The Energy Saving setting is a choice of four levels, given as percents. Energy Saving imposes a ceiling on the Backlight level. For example, if Energy Saving is set to Level 2 (60%), the Backlight scale is effectively reduced to 0 to 60, since any setting above 60 will function as 60.

Preventing and fixing ghost images

Displaying a static image on the screen for a long time can result in “burn-in” or image retention. To avoid image retention, do not display a fixed image for long periods of time. Either turn the display off, use one of the image retention choices (ISM) in the OSD, or change the image. You can help to avoid or correct ghost images by using one of the ISM Method options:

1.Navigate to the Option 2 submenu and then to the ISM Method option.

2.Select one of the following menu options:

●Orbiter — The image will move two pixels every two minutes, alternately moving left, right, up, and down. Orbiter will remain on until changed in the ISM Method menu.

●Inversion — This function can be used to fix a ghost or burned-in image. It will invert the image colors every 30 minutes. The inversion function will remain on until changed in the ISM Method 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.

●Dot wash — Imposes a pattern of black dots on the image and moves them every 5 seconds.

●OFF — Choose if you do not want the ISM function to be active. When the display is turned off, the ISM setting is lost and will be OFF when the display is next turned on.

Using Tile Mode

Tile Mode lets you define an array of up to 25 displays showing a single image. The array need not have the same number of columns as rows, and the displays can be in landscape or portrait orientation. Tile mode is designed for use with daisy chained displays receiving VGA or DisplayPort input. If the input source is Video Over Ethernet, each display must be sent the same image for tile mode to work. (See the Video Over Ethernet User Guide for details).
