Note:
Even if your PC’s setting is out of the range of video modes that are supported by your LCD monitor, it
may still be displayed with reduced quality. This provides you with an opportunity to change your PC’s
setting to a correct one.
The following are not malfunctions:
‧
The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an
abnormality appears on the screen as well.
‧
When a still image as been displayed for a long period, a faint residual image may remain on the screen for a short
time after the power has been turned off or when another image is displayed. The image will eventually
disappear.
‧
When you see the monitor from the side, the color or brightness look different.
‧
The LCD panel is made with high-precision technology and has more than 99.99% effective pixels.
Fewer than 0.01% of pixels may be chipped or always lit.
