TFT LCD PANEL
Black spots (pixels that do not light) or luminescent spots (pixels
that are always lit) may appear on the screen because of the
intrinsic characteristics of TFT LCD technology. This is neither a
malfunction nor a defect in the monitor. The warranty period for
the occurrence of black spots and luminescent spots is 1 month
from the date of purchase. Monitors with less than 3 such pixels
will not be exchanged.
The HMLCD15 uses high-voltage fluorescent tubes. If a portion
or whole of the screen becomes dark or flickers intermittently,
the monitor can be exchanged for free. Contact Customer
Service within one year of purchase date.
When the HMLCD15 is not in use, the screen must be turned off
or the pattern must be frequently changed by using a screen
saver. If the same pattern is displayed on the screen for a long
period of time, image sticking may occur or the life of the
monitor may be shortened.
Some computer systems are not compatible
with the DDC standard. If your monitor is
displaying the wrong resolution, check your
computer system for a DDC compatible video
card and contact the Service Center.
