10. For long-term use
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 been 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 main power of this monitor 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 you cover the panel surface of the main unit with a protective cover made of glass or acrylic, the panel surface will be
sealed and the internal temperature will rise.
Use the screen saver, the computer's power management function, or reduce the monitor's brightness to prevent the
internal temperature from rising.
• To reduce the load on the LCD panel, use [SCREEN SAVER] in the [PROTECT] OSD menu.
• Use [SCHEDULE] in the OSD menu to automatically power the monitor on or stand by at any time.


NOTEN:
When using the schedule function, be sure to set [DATE & TIME] in the [SYSTEM] OSD menu.
