The temperature of the display panel surface is
warm.
The LCD display panel works by lighting phosphors. In some cases, this may
cause the temperature of the panel surface to increase. Please note that this
is not a malfunction.
-
Points that do not light, points with brightness
different from that of the periphery, points with
color different from that of the periphery, etc.
High-precision technology is used to manufacture the LCD display panel,
However over the life of the LCD panel, a few pixel elements may fail. This is
not to be considered a defect in the panel.

Coarse horizontal stripes appear in FULL display.
Adjusting the Clock Phase will reduce the horizontal stripes. (RGB input)

The screen flickers in the form of horizontal lines
oscillating up and down.
(PC INPUT MODE only)
If the frequency from the computer is below 75Hz, try a higher frequency (to a
maximum limit of 75Hz). There may be a slight attenuation of the current
image.
The top surface of the monitor heats up.
When used for long periods of time, the top surface of the monitor may heat
up. This is not a malfunction.
-
Text characters are displayed with varying
thickness.
The thickness of characters and lines may vary when images with a vertical
resolution greater than 720 lines are displayed; however this is not a
malfunction.
-
The display does not seem bright enough.
The ambient temperature of the monitor may be low. Ambient temperatures
less than about 15° degrees, may cause lower luminance.
The panel protection circuit automatically lowers the luminance, and is not a
malfunction. The luminance will be restored when power is turned on for a
while.
-
The display does not seem bright enough. (RGB
input)
The setup-frequency setting in RGB input may be set to PC mode. When set
to PC mode, the luminance is lowered by about 10% than when set as Movie
mode. This is not a malfunction. If you do not mind flicker on the display,
please switch to Movie mode.
