B.4 Image Persistence

Image persistence refers to when a residual or “ghost” image of a previous
image remains visible on screen. Unlike CRT monitors, with LCD monitors
image persistence is not permanent. However, displaying constant images for
long periods of time should be avoided.

To alleviate image persistence, power off the monitor for the same length of time
as the image was displayed. For example, if an image was displayed on the
monitor for one hour and a residual image remains, the monitor should be pow -
ered off for one hour to erase the image.
B.5 Unstable, Unfocused, or Swimming Image

Check that the signal cable is securely connected to the monitor and the display
source device.

Check that the monitor is compatible with the display card and the settings are
configured correctly.

If text is presented on screen in a garbled manner, change the display mode
and set the refresh rate to 60Hz.
B.6 Incorrect Display Image Size

Check that the monitor and display source device are configured to the correct
display mode (refer to the display card or monitor user manual when changing
the graphics mode).
Note! As with all personal display devices, Advantech recommends using a
moving screen saver whenever the screen is idle and turning off the
monitor when not in use.
