10. Recommended adjustments
The backlight used for this monitor has a limited life and its brightness decreases with the usage time.
Also, if the same still image is shown for a long time, “Image Persistence” may occur. “Image Persistence” is a phenomenon
in which the image of an LCD remains visible after the device has turned off.
The “Image Persistence” is gradually eliminated by changing the screen, but if the same screen is shown for too long, the
“Image Persistence” will not disappear.
To avoid shortening this monitor’s lifetime, please note the following:
• Turn off the monitor’s main power switch when not in use.
• Use the
⏻ button on the main unit or the STANDBY button on the remote control to put the unit in standby mode.
• Use [POWER SAVE SETTINGS] in the [PROTECT] OSD menu. When there is no input signal the monitor will
automatically switch to power save mode.
• If using a cover made of glass or acrylic to protect the panel surface of the main unit, the panel is sealed and the internal
temperature rises.
Reduce the monitor’s brightness to prevent the internal temperature from rising. If the monitor is connected to a
computer, use the computer’s power management function to control the monitor’s automatic power off.
• To reduce the load on the LCD panel, use [SCREEN SAVER] in the [PROTECT] OSD menu.
• Use [SCHEDULE] in the OSD menu to automatically control the monitor’s on and standby power states as required.
NOTEN
When using the schedule function, set [DATE & TIME] in the [SYSTEM] OSD menu.
