About LCD Monitors

What you gain by using an LCD monitor in your industrial controls

are the future of display technology. CRTs, although they have dropped in

cost significantly, do not offer the performance, reliability, and mounting

options available with LCDs. LCD monitors consist primarily of an LCD, Video

Board and a Back Light video. The LCD determines to a large extent the

viewing angle, brightness and contrast. Beyond that it is the function of the video board which converts

the analog RGB (Red, Green, Blue) signals from a standard video card to a high quality, digital RGB that

the LCD can display.

Recently the video card has taken on a new role. It is the responsibility of this device to “scale” a

particular video resolution to the “native” resolution of the LCD. Simply, consider that a computer is

putting out a VGA [640x480] resolution signal, yet the LCD that is connected is an XGA [1024x768]

display. The displayed picture would be in the center 1/3 of the LCD. With the introduction of the scaling

engine. The converter will mathematically recalculate the 640x480 to 1024x768. This may sound simple

but it is in fact a complex algorithm that adjusts for different aspect ratios and pixel alignment, essentially

smoothing text and graphics to produce a picture that is pleasant to the eye.

Product Safety Precautions

This unit has been engineered and manufactured to ensure your personal safety, however

improper use may result in potential electrical shock or fire hazards. In order to allow the

proper operation of all safeguards incorporated in this display, observe the following basic

rules for its installation, use, and servicing.

On Safety

Use only the power cord supplied with the unit. In case you use another power cord, make sure that

it is certified by the applicable national standards if not being provided by the supplier. If the power

cable is faulty in any way, please contact the manufacturer or the nearest authorized repair service

provider for a replacement. The power supply cord is used as the main disconnection device.

Ensure that them socket-outlet is easily accessible after installation. Operate the display only from a

power source indicated in the specifications of this manual or listed on the display. If you are not

sure what type of power supply you have, consult with your service or maintenance department.

Overloaded AC outlets and extension cords are dangerous. So are frayed power cords and broken

plugs. They may result in a shock or fire hazard Call your service technician for replacement.

Do not Open the Display.

♦ There are no user serviceable components inside.

♦ There are Dangerous High Voltages inside, even when the power is OFF.

♦ Contact your dealer if the display is not operating properly.

To Avoid Personal Injury :

♦ Do not place the display on a sloping shelf unless properly secured.

♦ Use only a stand recommended by the manufacturer.

♦ Do not try to roll a stand with small casters across thresholds or deep pile carpets.

To Prevent Fire or Hazards:

♦ Always turn the display OFF if you leave the area for more than a short period of time.

♦ Do not drop or push objects into the display's cabinet openings. Some internal parts carry

hazardous voltages.

♦ Do not add accessories that have not been designed for this display.

♦ During a lightning storm or when the display is to be left unattended for an extended period of

time, unplug it from the wall outlet.

Important Precautions

On Installation

Do not allow anything to rest upon or roll over the power cord, and do not place

the display where the power cord is subject to damage.

Do not use this display near water such as near a sink, in a wet location where there is standing

water. Displays are provided with ventilation openings in the cabinet to allow the release of heat

generated during operation. If these openings are blocked, built-up heat can cause failures which

may result in a fire hazard.

Therefore, NEVER:

♦ Block any ventilation slots.

♦ Place the display in a built-in enclosure unless proper ventilation is provided.

♦ Cover the openings with cloth or other material.

♦ Place the display near or over a heat source.

Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,

mar, or damage the Active Matrix LCD permanently.

Do not press the LCD screen with your finger for a long time as this may cause

some afterimages.

Some dot defects may appear as Red, Green or Blue spots on the screen.

However, this will have no impact or effect on the display performance.

If possible, use the recommended resolution to obtain the best image quality for

your LCD display. If used under any mode except the recommended resolution,

some scaled or processed images may appear on the screen. However, this is

characteristic of the fixed-resolution LCD panel.

On Cleaning

Unplug the display before cleaning the face of the display screen. Use a 50/50 mix of Isopropyl

alcohol and water. Apply with a slightly damp (not wet) lint free cloth. Do not use an aerosol directly

on the display screen because over-spraying may cause electrical shock.

On Repacking

Do not throw away the carton and packing materials. They make an ideal container in which to

transport the unit. When shipping the unit to another location, repack it in its original material.

of the LCD and connect to a known good computer CRT display. If the computer display is

working satisfactory and the video is within the appropriate range, then contact VarTech

Customer service for a RMA number.

Connecting the Display

1. Connect all cables to the computer first. This would include the VGA cable and the optional RS

232 serial touch screen connection.

2. After connecting the cables between the LCD monitor and the computer, plug the power cord into

the 115/220VAC power outlet if using using the optional AC to 12VDC power supply.

5. Your display should now operate as a normal computer display showing your windows or

whatever video is being sent to the flat panel.

Note:

If for any reason the display goes blank and gives an “out of Range” or “No Sync”, your computer

or video source is putting out a signal that is out of range of the LCD’s video board. If this happens,

reboot the computer or video source and make sure you are inputting the correct signal. If the dis-

play doesn’t work properly, it may be because:
