PROTECT MENU
SCREEN SAVER
Use the [SCREEN SAVER] function to reduce the risk of Image Persistence.
NOTE:
• When the screen saver starts, the image aspect is changed to [FULL]. When the screen saver
stops, the aspect will return to the current [ASPECT] setting.
• The screen saver cannot be selected for a signal input of 4K.
• When the [MOTION] is active, [ASPECT] and [OVERSCAN] are not available.
• This function will be disabled when activating [TILE MATRIX] or pressing STILL button on the
remote control.
MOTION Slightly expands the screen image to the pre-set zoom level then moves the image in four directions (up,
down, right, left) at the pre-set interval. Use the + and – button on the remote control to set the time on the
[INTERVAL] slider, and the zoom percentage on the [ZOOM] slider.
POWER ON DELAY Delays the monitor from turning on for the amount of time set when the POWER ON button is pressed.
DELAY TIME The delay can be set between 0 and 50 seconds.
LINK TO ID Links the [DELAY TIME] to the monitor’s ID. This helps to prevent power surges that may occur if all
multiple monitors were to turn on at the same time. The higher the Monitor ID, the longer the delay is
before the monitor powers on.
For example, if the Monitor ID is 20 and the [DELAY TIME] is 5 seconds, the amount of time that passes
between when the POWER ON button is pressed and when the power actually turns on is 95 seconds.
NOTE:
If the [DELAY TIME] is set to 0 seconds, there will be no extended delay for [LINK TO ID].
The delay time must be 1 second or higher to delay power on.
