Chapter 1 Installation

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:

* LCD Monitor * User's Manual

* 1.8M Monitor-to-PC VGA Cable

* 1.8M Monitor-to-PC DVI-D Cable

* AC Adapter

* 1.8M Power Cord

* 1.8M Stereo Jack Audio Cable * 1.8M S-Video Cable

* 1.8M RCA Jack Audio Video Cable

If you find that any of these items is missing or appears damaged, contact your dealer immediately.

Connecting the LCD Monitor and Base

When you open the box to take the base and put on the desk first. Then connect the LCD Monitor and base and screw it locked please. (See fig.1-1 )

DVI Port your PC.

4. Make sure connection are secure .

Video Connector

Figure 1-5

Attention: This device must be connected to an off-the-shelf video cable in order to comply with FCC regulations. A ferrite-core interface cable is included in the LCD Monitor package.

This device will not be in compliance with FCC regulations when a non-ferrite-core video cable is used.

Connecting the AC Power

1. Connect the power cord to the AC adapter.(See Fig. 1-6)

2. Connect the AC adapter’s DC output connector to the DC Power Jack of the monitor.

3. Connect the power cord to an AC power source.

Power Cord

AC Adapter

Warning: We recommand to install a “Surge Protector” device between the AC Adapter and the electrical wall outlet for adding protection against power surges to prevent the errects of sudden voltage variations from reaching the LCD Monitor. Sudden power surges may damage your monitor.

DC Power Jack

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: 30

~ 80 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 ”.
