About LCD Monitors
What you gain by using an LCD monitor in your industrial controls
LCDs
LCDs
LCDs
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.

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 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.
3. Once 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.
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.

TOUCH SCREEN
TOUCH SCREEN
Touch Screen Introduction
Touch screen interfaces have become the standard interface in the past 5 years. They are,
rugged, reliable, extremely flexible and easier than ever to implement! Over 90% of the
display packages Vartech Systems builds are touch screen systems. If you are uncertain
about using a touch screen, or are having difficulty, please call us. The universal acceptance
of the Windows GUI [Graphical User Interface] along with the extensive use of a mouse
interface has significantly accelerated the use of touch interface. Basically think of your touch
screen as if it were a mouse.
4.1
4.2
Quite simply, Vartech Systems touch systems are a mouse emulator. By installing a software
driver and connecting to a serial port, the touch screen will support all the primary mouse
functions:
Our standard touch screen interface, is a high resolution analog resistive. Following is a quick
explanation of what all this means.
High Resolution: The touch screen resolution is 400 ppi [points per inch]
Analog Resistive: The actual touch glass is an analog device. Meaning there is a very low
voltage applied to the X and Y axis of the touch screen. This current is applied to ITO [Iridium
Tin Oxide] that is sputtered onto a polyester membrane. When you touch the screen you are
changing the resistance on both the X and Y axis, producing an analog value that references
a particular location.
This type of screen can be activated with a gloved finger or mechanical stylus.
The touch screen itself is connected to electronics that provide the Analog to Digital
conversion. When the screen is touched, the electronics convert the analog voltage to a
digital value and add a “Mouse Click”, then sends the data to the serial port that the driver is
loaded to. When the touch is released the new XY location is sent along with a “Mouse Up
Click”.
This system requires no special software knowledge, and can be installed and set up in
minutes. The following section gives a detailed explanation of the software setup and
configuration.
Since the touch screen interface is RS-232, the recommend maximum distance from the PC
is 50 feet. In reality, every application is different. The touch driver default baud rate is 9600,
and we have tested the driver and interface with good quality cables to 50 feet.
With RS-232 line drivers this can be extended almost indefinitely.

Connecting the touch screen
1. Make sure all optional cables have been received.
2. Connect one end of the 6 foot touch screen serial cable to the touch screen port D9
connector on the side of the monitor.
3. Connect the other end to any communications port on the host computer.
4. Tighten the captive screws on the cable connector to secure it.
4.3 Touch Screen Serial Interface
All touch controllers are configured by default to provide serial communications at 9600 baud,
8 data bits, 1 stop bit, no parity. For Vartech flat panels equipped with touch screens, a serial
communications cable is required. This 6 foot cable comes with the unit in the accessory kit.
The cable is a straight wired serial (RS-232) cable with a male
DE-9 D-shell connector on the monitor end. The cable provides a communications channel
between the touch screen controller, which is mounted inside the monitor, and an RS-232
serial port on the host computer.
Because the touch controller obtains power from the monitor's power supply, no external touch
power connections are necessary.
Software supplied with the touch screen must be loaded on the host computer to handle
communications with the touch controller over the channel.
Because the touch screen emulates a mouse, there may be compatibility issues involving how
the touch screen emulates mouse buttons, especially multiple buttons.
4.4 Setting up the Touch Screen Interface

Enabling the Touch Screen Interface
The Flat Panel Monitor provides a female DE-9 connector for the touch interface.
This connector provides the serial interface for the touch controller.
Interconnecting wiring to the host serial port connection is shown in the following table.

Trouble Troubleshooting Tip
No Picture ⇒ 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 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.
Picture Quality & Image Stability ⇒ 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.
Green LED not lit Check for proper power and power connections
Green LED blinking This indicates absence of video or proper video for this display
Display image is not properly
sized
⇒ Adjust the Vertical and Horizontal size controls via the OSD.
(Reference setup adjustments)
⇒ Ensure that a supported mode is selected on the display card
or system being used. Consult the display card or system
manual for proper video.
No S-Video or NTSC operation ⇒ Check for proper connections.
⇒ Check the setup instructions for proper input selection.
If these tips do not solve your problem, contact Vartech Systems Customer Service support.

CLEANING AND MAINTANENCE
CLEANING AND MAINTANENCE
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.
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.
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.
16
Note:
The solvent should be applied only to the cloth, and not directly on the monitor 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.
