INTRODUCTION
SECTION 1
1.1 About LCD Monitors
A liquid crystal display (LCD) is a thin, flat panel used for electronically displaying information such
as text, images, and moving pictures. Among its major features are its lightweight construction, its
portability, and its ability to be produced in much larger screen sizes than are practical for the
construction of cathode ray tube (CRT) display technology. Its low electrical power consumption
enables it to be used in battery-powered electronic equipment. It is an electronically-modulated
optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light
source (backlight) or reflector to produce images in color or monochrome.
The LCD determines 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.
The Video Card is the responsible for allowing the 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.

Users Manual
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 120VAC source to the 120VAC connection on the rear.
3 Once the 120VAC connection is made and switched on, 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 OS or the video
that 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 too high or low for the LCD.
(b) The refresh rate is set too 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.
(c) The power source is incorrect.
(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) used with this monitor is equipped
with a conventional HD-15 connector at each end.

SECTION 4
TOUCHSCREEN
4.1 Introduction
Touch screens are a common means to interface operator inputs to a system. The universal
standard of Windows GUI (Graphical User Interface) has significantly increased the use of touch
screens.
There are four main touch technologies. The technologies are resistive, surface acoustic wave
(SAW), capacitive, and infrared (IR). Each touch technology has advantages and
disadvantages based on different user applications.
4.2 Installation
All Vartech Systems displays configured with a touch screen are supplied with a CDROM which
includes user manuals, application software, and drivers for various operating systems. Insert the
supplied CDROM into a CDROM drive and follow the installation instructions that will appear on the
screen.
Technical support is available by contacting Vartech Systems customer support at 800-223-
8050.
SECTION 5
5.1Troubleshooting
General
A general guide to troubleshooting a flat panel display system it is worth considering the system as
separate elements, such as: Controller (jumpers, PC settings) Panel (controller, cabling, connection,
panel, PC settings) Backlight (inverter, cabling, backlight tubes) Cabling Computer system (display
settings, operating system) Through step by step cross checking with instruction manuals and a
process of elimination to isolate the problem it is usually possible to clearly identify the problem area.
No image:
If the panel backlight is not working it may still be possible to just see some image on the
display. A lack of image is most likely to be caused by incorrect connection, lack of power,
failure to provide a signal or incorrect graphic card settings.

13
Image position:
If it is impossible to position the image correctly, ie the image adjustment controls will not move the
image far enough, then test using another graphics card. This situation can occur with a custom
graphics card that is not close to standard timings or if something is in the graphics line that may be
affecting the signal such as a signal splitter (please note that normally a signal splitter will not have
any adverse effect).
Image appearance:
A faulty panel can have blank lines, failed sections, flickering or flashing
display, incorrect graphics card refresh rate, resolution or interlaced
mode will probably cause the image to be the wrong size, to scroll,
flicker badly or possibly even no image. Incorrect jumper settings on the
controller may cause everything from total failure to incorrect image.
CAUTION: Do not set the panel power input incorrectly. Sparkling on the
display: faulty panel signal cable.
Backlight:
Items to check include: Power input, Controls, Inverter and Tubes generally in this order. If half the
screen is dimmer than the other half: Check cabling for the inverter. For a specific backlight tube
check the AC pins orientation (CAUTION: Never reverse any DC power pins). Also: If adjusting
brightness control has no effect the chances are that the VR rating or method of adjusting brightness
is not compatible or correctly connected to the inverter. If system does not power down when there
is a loss of signal
Continued failure:
If unit after unit keeps failing consider and investigate whether you are short circuiting the
equipment or doing something else seriously wrong.
Generally after common sense issues have been resolved we recommend step by step
substitution of known working parts to isolate the problem.
SECTION 6
6.1 Cleaning
Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a mild
(non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to
avoid scratching it with accumulated grit.
Note:
The solvent should be applied only to the cloth, and not directly on the monitor screen.

14
Do not use paper products as they may scratch the surface. To minimize the risk of abrasion, allow
the screen to stand dry. Special care should be taken when cleaning a touch screen or
polycarbonate shield that is installed over the screen. Abrasive and certain chemical cleaners can
easily damage the surface. Never use alcoholic or ammoniac cleaners to clean the polycarbonate
shield or a touch screen.
Note:
For best results cleaning a monitor with the optional antireflective tempered glass display shield, a
solution of denatured alcohol is recommended to thoroughly clean the display.
Replacing a Line Cord
To avoid shock and fire hazards, the monitor’s power cord should be replaced if the insulation
becomes broken or if it develops a loose internal connection.
Other Maintenance
Qualified service personnel should perform all maintenance, except for the power cord replacement
described above.
SECTION 7
7.1 Panel Mount Procedure
