Chapter 1 Installation
1.1 Unpacking
Before unpacking the LCD Monitor, prepare a suitable workspace for your Monitor and computer. You need a stable and clean surface near a wall power outlet. Make sure that LCD Monitor has enough space around it for sufficient airflow. Though the LCD Monitor uses very little power, some ventilation is needed to ensure that the Monitor does not become too hot. After you unpack the LCD Monitor, make sure that the following items were included in the box:
Main body x1 1.8M Audio cable x1 Power supply x1 User manual x1 1.8M VGA cable x1
If you find that any of these items is missing or appears damaged, contact your dealer immediately.
1.2 Pull down the base
When you open the box to take the product out then pull down the base first (See figure 1-1)
Figure 1-1
1.3 Viewing Angle Adjustment
The LCD Monitor is designed to allow users to have a comfortable viewing angle. The viewing angle can be adjusted from -5°to +25°.(See fig. 1-2)
Figure 1-2
When you want to close the base and body to 90°, you need to release a button from 25°. (See fig. 1-3)

3.3 Troubleshooting
This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output timing differences among various VGA cards in the market, users may initially experience an unstable or unclear display whenever a new display mode or new VGA card is selected.
Attention
This LCD Monitor Supports Multiple VGA Modes. Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor.
PROBLEM Picture is unclear and unstable
The picture is unclear and unstable, please perform the following steps :
1. Enter PC to “Shut Down Windows” status while you’re in MS-Windows environment.
2. Check the screen to see if there’s any black vertical stripes appear. If there are, take advantage of the “Clock” function in OSD menu and adjust (by increment or decrement numbers) until those bars disappear.
3. Move to “Phase” function in OSD menu again and adjust the monitor screen to its most clear display.
4. Click “No” on “Shut Down Windows” and back to the normal PC operating environment.
PROBLEM There is no picture on LCD Monitor
If there’s no picture on the LCD Monitor, please perform the following steps:
1. Make sure the power indicator on the LCD Monitor is ON, all connections are secured, and the system is running on the correct timing. Refer to Chapter 3 for information on timing.
2. Turn off the LCD Monitor and then turn it back on again. If there is still no picture, press the Adjustment Control button several times.
3. If step 2 doesn’t work, connect your PC system to another external CRT. If your PC system Functions properly with a CRT Monitor but it does not function with the LCD Monitor, the output timing of the VGA card may be out of the LCD’s synchronous range. Please change to an alternative mode listed in the Standard Timing Table or replace the VGA card, and then repeat steps 1 and 2.
PROBLEM There is no picture on LCD Monitor
If you have chosen an output timing that is outside of the LCD Monitor’s synchronous range (Horizontal: 24 ~ 60 KHz and Vertical: 56 ~ 75 Hz), the OSD will display a “Out of Range” message. Choose a mode that is supported by your LCD Monitor. Also, if the signal cable is not connected to LCD monitor at all or properly, the monitor screen will display a
message “No Input Signal”.
