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.

All Vartech displays from 12.1” (800x600) to 23.1 (1600x1200) incorporate scaling engines in the

converter card.

Product Safety Precautions

 Ensure that sufficient space is available around the display to provide the circulation

necessary for cooling.

 Ensure that the ambient air temperature will not exceed the specified maximum

temperature.

 Do not attempt to service this display yourself. The rear chassis has a seal so that non

qualified personal will not expose themselves to dangerous voltages or other risks.

 To protect from electrical shock, unplug the display power supply from the wall before

moving.

 Do not expose the display to direct sunlight or heat.

 Do not use this display near water

 Do not place any heavy objects on the power cords. Damage may cause electrical shock.

 Unplug the power supply from the wall or unit if one of the following conditions exists.

 Power cord or plug is damaged or frayed

 Liquid is spilled into the display or the display is exposed to rain or water.

 The display does not operate normally when the operating instructions are

followed.

 The display has been dropped or the enclosure has been damaged.

 The display exhibits a distinct change in performance, indicating a need for

service.

2.2 Unpacking and setting up your display

Your LCD monitor package will consist of the components listed below. Open shipping

container and lay all components on a flat clean surface.

2.3 What is included with your display

2.4 Connecting the Display

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

RS 232 serial or USB touch screen connection.

2. After connecting the cables between the LCD monitor and the computer, plug the customer

supplied +12VDC or 90/264 VAC source to the 12V connection on the rear.

3. Once the +12V connection is made, the display is active.

4. If your computer was off, turn on your computer.

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 Input Signal”,

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

(a) The resolution is to high or low for the LCD.

(b) The refresh rate is set to high. Refresh on an LCD is different than a CRT. Set the refresh to

60Hz. CRT’s need a high refresh rate to avoid flicker. The refresh rate has no impact on

LCD’s.

(d) The unit is malfunctioning. If you believe this to be true, disconnect the video cable from the

rear 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 at 800-223-8050.

2.5 Signal Connections

To avoid irregular operation and /or damage to the display, please insure correct video is being

supplied as shown on the following page.

You can use an HD-15 connector cable or a BNC adapter cable to connect the flat panel

monitor to the host computer. The HD-15 video cable (supplied in the kit) you use with this

monitor is equipped with a conventional HD-15 connector at each end.

Note:

The following figure is the view looking into the pin end of the male connector or solder term

end of the female connector.

Optional BNC Adaptor Cable

A 5BNC-to-HD15 adapter cable is available. The functions of the cables are described below.

 R, B, and G: Red, Green, and Blue input connectors to establish color.

These are used for RS-343 analog signals.

 HS/CS: Separate horizontal/composite sync signal from the video

source.

 VS: Separate vertical sync signal from the video source.
