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 circula-

tion 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 instruc-

tions 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.

⇒ VT170R or VT170P, or VT170C or VT170W LCD Monitor

⇒ 5 ft Video Cable

⇒ Chassis model only has a +12V power connection. (115/220VAC Power Supply is optional)

⇒ 10-32 Mounting Hardware. (For use with Panel Mount only)

⇒ 6 ft RS232 Touch Interface Cable (Optional when touch is installed)

⇒ CD ROM with Touch Screen Drivers (Optional when touch is installed)

⇒ Users Manual

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 customer

supplied +12VDC source to the 12V connection on the rear (Chassis model only) . All other

models have a integrated 115/220VAC power supply.

3. Once the +12V or the 115/220VAC 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.
