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.

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 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.

VT190 DiamondVue User Guide 150-065
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.
