About LCD Monitors
What you gain by using an LCD monitor in your industrial controls
are the future of display technology. Although CRTS have dropped in cost
significantly, they do not offer the performance, reliability, and mounting
LCDs
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.
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 function
All Vartech displays from 12.1” (800x600) to 23.1 (1600x1200) incorporate scaling engines in the
converter card.

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
customer supplied +12VDC source to the 12V connection on the rear or the 12VDC
connection from the output of the optional 115/220VAC 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.
(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.

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.
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.
Limited technical support is available by contacting Vartech Systems customer support at
800-223-8050.

Image Persistence
Picture Quality & Image
Stability
• The signal cable should be properly connected to the display
card and computer.
• Try disconnecting the video cable from the display and
connecting to a CRT display if available to confirm the
presence of proper video.
• Make sure power is connected to the proper DC or AC
source.
• Make sure the resolution mode is supported by the display
and check settings of the display card.
• Confirm that the video cable is not defective.
Image persistence occurs when a ghost of an image remains on
the screen after the monitor has been turned off. Unlike a CRT
monitor, an LCD monitor’s image persistence is not permanent.
To erase an image ghost, turn the monitor off for as long as the
image was displayed. If the image was on for one hour and the
ghost of the image remains, the display should be turned off for
one hour to erase the image. To avoid this problem, use a screen
saver.
• Check for proper video cable for proper grounding and
shielding.
• Check the signal source for proper signal.
• Check for proper adjustment of the Phase and Frequency
controls.
• Check for proper recommended signal timing.

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.
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.
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.
Never use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a touch screen.
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.

Chassis Mount Procedure
Mounting instructions for chassis mount
The chassis mount contains a simple frame with mounting holes. Traditionally captive hardware
would be used to secure the display against a panel with the proper hole size based on the mechanical drawing. The chassis display is supplied with a piece of Plexiglas material sealed to the front for
protection. If the display is equipped with a touch screen, the touch screen takes the place of the
Plexiglas for protection of the LCD.
The unit is normally supplied for +12V operation, however it is available with a 115/220VAC supply.
7.2
Panel Mount Procedure
Panel Mounting Procedure
1. Cut and drill the panel (refer to panel mount drawing). Measurements are in inches.
Panel Mounting Cutout
2. If access to the side of the monitor is not available following installation, attach the power
and video cables to the side of the monitor at this time.
3. Install the monitor in the prepared cutout.
4. Install the lock nuts and washers, supplied with the monitor, behind the holes running along
the sides and top/bottom of the cutout in the panel. Extra lock nuts and washers are provided.
Note: Use #10-32 nuts for mounting.
5. Tighten all mounting nuts evenly to a torque of 24 inch-pounds.
ATTENTION: Mounting nuts must be tightened to a torque of 24 inch-pounds to provide panel
seal and avoid potential damage. Vartech Systems assumes no responsibility for water or
chemical damage to the monitor or other equipment within the enclosure due to improper
installation.
6. Attach the power and video cables to the side of the monitor if you have not already done
so.
