CHAPTER 2
Introduction to Flat-Panel Displays
Overview
The 3M Touch Systems product line of Flat-Panel Display (FPD)
touch monitors offers the CT150 monitor for kiosk, ATM, and
industrial enclosures.
All CT150 monitors are encased in rugged metal instead of plastic.
The CT150 monitor features a touch screen interface, several
mounting options, and sturdy construction.
The CT150 is available in a 15" diagonal screen size. The flat-panel
display uses active-matrix thin-film transistor (AM-TFT) liquid
crystal display technology. The CT150 monitor supports a
full-screen resolution of 1024 x 768.
Note: The CT150 has five buttons for using the on-screen menu and
adjusting the video display. Refer to Chapter 4 for more information on
these controls.
The monitor is available with 3M Touch System’s ClearTek®
capacitive touch screens. Capacitive is the touch screen of choice for
public access applications requiring high levels of durability and
reliable performance 24 hours a day, 7 days a week.
The monitor also features space saving designs, high resolution, low
radiation, and low power consumption. These qualities make the
CT150 touch monitor ideal for applications that require superior
color, resolution, and clarity.

14 CT150 FPD Monitors
3M Touch Systems Proprietary Information
Video Resolution on a Flat-Panel Display
Flat-panel displays, unlike CRTs, are optimized to run at one
resolution. A flat-panel display has discrete points on the display
that determine the exact location of a pixel. Each flat-panel display
has an exact number of pixels associated with it. There is a one-to-
one mapping between the number of pixels and the video
addressability, sometimes called resolution.
Native Video Resolution
A flat-panel display should be used only at the resolution dictated by
the number of pixels on the panel. The CT150 monitor has 1024
pixels across the screen and 768 lines of pixels down the screen and
can accurately display one resolution (1024 x 768) at full screen.
Options for Using Other Video Resolutions
The 3M Touch Systems CT150 FPD monitor supports all standard
resolutions up to their respective native resolution for monitor setup.
Many video cards initially display a screen image at the SVGA or
VGA resolution. By supporting these resolutions, the monitor can
display the desktop controls that let you change to the optimal
resolution of 1024 x 768.

CHAPTER 3
Setting Up Your CT150 Monitor
This chapter describes how to set up and integrate your 3M Touch
Systems CT150 monitor into a touch application. You need to
complete the following tasks:
• Unpack the components
• Connect the video, touch screen, and power cables
• Power on the monitor and test your setup
• Install the touch screen software
• Calibrate the touch screen
System Requirements
The CT150 flat-panel touch monitors require a personal computer
(PC). These touch monitors are not supported on Macintosh
computers.
The requirements for your PC are as follows:
• Your PC must have an available RS-232 serial communication (COM)
or USB port. You connect the touch screen to this port.
• Your PC must have a unique interrupt request (IRQ) available to the
COM port that the touch screen will use. The touch screen cannot
share an IRQ with another device.
• Your PC must have a video card and video driver already installed for
the monitor. If you need to install a video card or a video driver, refer
to your computer documentation for instructions.
When choosing your workspace, select a sturdy, level surface. Also,
make sure you can easily access the back of the touch monitor and
the computer. Easy access helps ensure a smooth setup of the touch
monitor.
Note: Before setting up your CT150 FPD, refer to the “Important Safety
Information” section at the beginning of this document.

Unpacking Your Touch Monitor
Carefully unpack the carton and inspect the contents. Your CT150
includes the following cables and accessories:
• SVGA video cable
• RS-232 serial communication cable (or USB cable if applicable)
• Optional AC/DC power supply (12V DC output)
• AC power cable
• CD with touch screen software, documentation, and utilities
• Hardware kit (includes mounting brackets, screws, washers)
Mounting the CT150 Monitor
The CT150 monitor is designed to fit any type of enclosure. All
CT150 monitors are encased in rugged metal instead of plastic,
making them easy to integrate.
The monitor has a bezel already mounted to act as an interface with
a front mounting surface.
The CT150 monitor includes a hardware accessory kit for mounting
the unit into an enclosure. The CT150 hardware accessory kit
includes two brackets, washers, and screws. The mounting holes are
located on the sides of the monitor and are threaded to an M4 thread.
You can attach the brackets to the edges of the chassis. The brackets
are slotted, allowing the chassis to slide in and out. You can also
rotate the brackets to various positions.
The unit has a 75mm VESA mounting pattern on the back case to
allow for arm mount capability.
Note: Do not mount the chassis unit directly from the rear of the cover.
Always use the holes and brackets provided. Do not drill additional holes in
the unit to mount brackets in other locations.
Access to the Video Controls
The controls for adjusting the video display are located on the back
of the CT150 monitor. These buttons let you display the on-screen
menu and adjust the phase, image position, contrast, and brightness.
Make sure you will be able to access the video controls once the
CT150 monitor is installed.

Chapter 3 Setting Up Your CT150 Monitor 17
3M Touch Systems Proprietary Information
Clearance and Ventilation
Leave at least two inches of clearance space behind the CT150
monitor for proper ventilation. Units have vent holes at the top and
bottom on the back of the chassis -- ensure these holes are not
blocked during installation. Always maintain adequate ventilation to
protect the display from overheating and to ensure reliable and
continued operation. Refer to the published specifications for the
maximum and minimum operating temperature and humidity
conditions.
Securing and Routing System Cables
You must be sure to secure all cable connections. Shaking and
vibration, especially during shipment, may dislodge components that
are improperly connected.
• Be sure to tighten all cable screws.
• Route all wiring and cabling away from heat sources and sharp metal
edges to avoid damage. Also, keep the touch screen cable away from
sources of electromagnetic and radio frequency interference.
Installing the Video Card and Video Driver
Before you can connect your touch monitor, make sure your
computer has a video card already installed for the monitor. After
you connect the monitor, you need to install the video software
driver. The video driver is supplied by the video card manufacturer
and may be found on the CD that came with your computer. If you
need information on installing a video card or video driver, refer to
the manual that came with your video card.
Supported Video Display Modes and Refresh Rates
Your video card must support one of the display modes specified in
Table 1. If you select an unsupported video mode, the monitor will
stop working or display an unsatisfactory picture quality.

Configuring the Display Settings
After you connect your CT150 and turn on your computer, you may
need to configure one or more of these display settings. The ideal
settings for these monitors are as follows:
• Display mode (also called desktop area or video resolution) 1024 x 768
• Refresh rate (also called vertical scan rate or vertical sync) 60 Hz
• Color depth (also called color palette or number of colors) at least 16-
bit (high color)
Using the Standard Controls for the Video Card
In addition to the standard controls on the monitor, each video card
has several controls that let you adjust the display settings. The
software and driver for each video card is unique. In most cases, you
adjust these settings by using a program or utility provided by the
manufacturer of the video card.
For example, you can use the Windows Display Properties control
panel to adjust the desktop area (resolution), color depth, and refresh
rate. Whenever you change these settings, the image size, position,
or shape may change. This behavior is normal. You can readjust the
image using the monitor controls described in this chapter.
