● compliance with the recommendations in accordance with TCO’03
This operating manual contains important information you require to start up and run your LCD monitor.
This specification defines the requirements for the 23” MICROPROCESSOR based Multi-mode supported high
resolution color LCD monitor. This monitor can be directly connected to general 15-pin D-sub VGA, 24-pin DVI and
21-pin HDMI connectors, also supports VESA DPMS power management and plug & play function.
Additional information
Due to the nature of liquid crystal display (LCD) technology, the picture resolution is always fixed. For the best
display performance, please set the display resolution to 1920x1080 pixels. This is called “Native Resolution” or
maximal resolution – that is, the clearest picture. Lower resolutions are displayed on a full screen through an
interpolation circuit. Image blurring across pixel boundaries can occur with the interpolated resolution depending
upon the image type and its initial resolution.

Frequently asked questions (FAQ)
The image is blurred: Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select the correct
resolution, refresh rate and make adjustments based on these instructions.
How do you use a VGA extension cable?
Remove the extension cable for the test. Is the image now in focus? If not, optimize the image by working
through the instructions in the "Adjusting the refresh rate" section on the link "Adjusting the Screen
Resolution". It is normal for blurring to occur due to conduction losses in extension cables. You can minimize
these losses by using an extension cable with better conduction quality or with a built-in booster.
Does the blurring only occur at resolutions lower than the native (maximum) resolution?
Read the instructions on the link "Adjusting the Screen Resolution" on the CD. Select the native resolution.
Pixel errors can be seen: One of several pixels is permanently black, one or more pixels are permanently white, one or more pixels are
permanently red, green, blue or another color.
• Clean the LCD screen.
• Cycle power on-off.
These pixels are permanently on or off. And it is a natural defect that occurs in LCD technology.
