example:
Panel Type: AMVA+ LED
Minimal space requirements thanks to slim casing
Optimum ergonomic characteristics (totally distortion-free, excellent picture definition and color purity right into
the corners)
Contrast ratio 3000:1(Type), 20M:1 (DCR), brightness 250nits
MAX. resolution (1920X1080)
Presentation of up to 16.7 M colors (in conjunction with an appropriate graphics card)
Automatic scanning of horizontal frequencies from 30 to 83 kHz and refresh rates (vertical frequencies) from
50 to 76 Hz (absolutely flicker-free)
Digital screen controller with microprocessor for storing 8 different display modes
Freely adjustable color alignment for matching the screen colors to the colors of various input and output
devices
Convenient operation via integrated OSD (On-Screen-Display) menu
VESA-DDC compatibility
Plug & play capability
Power management for reducing power consumption when the computer is not in use
This operating manual contains important information you require to start up and run your LED monitor.
This specification defines the requirements for the 24″ MICROPROCESSOR based Multi-mode supported high
resolution color LED monitor. The monitor can be directly connected to general 15-pin VGA connector and 19-pin
HDMI connector. Also support 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 with an aspect ratio of 16:9. 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.

Troubleshooting
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 that is a natural defect occurs in LED technology.
The image has a faulty coloration:
It has a yellow, blue or pink appearance.
Select MENU > PICTURE > Color > Reset Color, and then choose “YES” in the “Caution” message box to
reset the color settings to the factory defaults.
If the image is still not correct and the OSD also has faulty coloration, this means one of the three primary
colors is missing in the signal input. Now check the signal cable connectors. If any pin is bent or broken off,
please contact your dealer to get necessary support.
No image can be seen:
Is the prompt on the display illuminated in green?
If the LED is illuminated in green and there is a message “Out of Range” on the screen, this means you are
using a display mode that this monitor does not support, please change the setting to one of the supported
mode. Please read the “Preset display modes” section from the link "Adjusting the Screen Resolution".
Faint shadow from the static image displayed is visible on the screen:
Activate the power management function to let your computer and monitor go into a low power "sleep"
mode when not actively in use.
Use a screensaver to prevent the occurrence of image retention.

Is the prompt on the display illuminated in orange?
If the LED is illuminated in orange, the power management mode is active. Press any button on the computer
keyboard or move the mouse. If that does not help, check the signal cable connectors. If any pin is bent or
broken off, please contact your dealer to get necessary support.
Is the prompt on the display not illuminated at all?
Check the power supply mains socket, the external power supply and the mains switch.
The image is distorted, flashes or flickers:
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.
You are running the monitor at its native resolution, but the image is still distorted.
Images from different input sources may appear distorted or stretched on the monitor running at its native
resolution. To have the optimal display performance of each type of input sources, you can use the "Display
Mode" function to set a proper aspect ratio for the input sources.
The image is displaced in one direction:
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.
The OSD controls are inaccessible:
To unlock the OSD controls when the OSD is preset to be locked, press and hold the “MENU” key for 15
seconds to enter the “OSD Lock” option and make changes.
