INTRODUCTION AND OVERVIEW

The Wacom® DTU-1931 pen display combines the benefits of a Liquid Crystal Display (LCD) with
the control, comfort, and productivity of Wacom’s cordless, battery-free pen technology. This gives
you a direct pen-on-screen interface for your computer.

The basic components of the DTU-1931 include a Wacom pen tablet internally mounted behind a

19.0" diagonal TFT color display, and a Wacom pen.
The display and tablet sensor function as an integrated output and input device. The display

supports resolutions up to 1280 x 1024 pixels at 16.7 million colors. The tablet sensor reports pen
coordinates, pressure, and switch information.

The DTU-1931 also comes equipped with a video pass-thru (
simultaneously connect a monitor or projector to the pen display.

This manual describes how to install and use your DTU-1931.

The computer treats the DTU-1931 pen display as two separate devices (the display and the
pen tablet). Therefore, the installation process is completed in two stages:

• First install the DTU-1931 as a display.

• Then install the DTU-1931 as a pen tablet.

Both stages require hardware and software installations and adjustments. Please follow all

instructions carefully.

IMPORTANT: You MUST install the Wacom pen tablet driver software for correct pen-on-

screen functionality.

INSTALLATION

SYSTEM REQUIREMENTS

Before installing the DTU-1931, make sure your computer meets the following minimum system
requirements:

• PC. Windows Vista™, Vista X64, XP, or XP x64. VGA or DVI video connector, available USB

port, and CD-ROM drive.

• Macintosh. OS X, v10.3.9 or greater. VGA or DVI video connector, available USB port, and

CD-ROM drive. ADC connectors require an ADC to DVI adapter, not included.

The DTU-1931 supports both analog (VGA) and digital (DVI) video signals. If updating your video
card, complete the video card hardware and software installation before connecting the DTU-1931.
If you have another display that is compatible with your video card, you can connect that display to
the card in order to verify the video card is operating correctly.

Although you can quickly connect the DTU-1931 to either a VGA or DVI video card, connecting to a
DVI video card generally results in optimum performance.

Notes:

Depending on the capabilities of your video card and operating system, you may be able to set up the
DTU-1931 as a mirrored, extended, or independent display. Refer to your video card documentation for
more information on its capabilities.

When you are working with more than one monitor, the DTU-1931 will map to the monitors based upon
how your system is configured. By default, if you are in mirror mode, the pen tablet will map to the entire
space on each monitor. See your hardware and operating system documentation for details on
configuring your computer and operating system for use with multiple monitors.

A display toggle function is available for use with multiple monitor systems. This enables you to toggle the
screen cursor between the DTU-1931 pen display and your other monitors. For more information, see the
electronic Software User’s Manual.

The DTU-1931 can be used alone or with another display. You may connect a second device, such as a
monitor or LCD projector, to the DTU-1931 DVI-I OUT port. When using this port, the second device will
mirror the image on the DTU-1931. Complete the DTU-1931 installation before connecting a projection
device to the unit.

There are two primary steps to the installation process:

• Step 1: LCD monitor installation

• Step 2: Pen tablet installation

Be sure to follow ALL instructions carefully.

Notes:

Each DTU-1931 LCD panel is produced under very stringent quality standards. Production techniques
cannot guarantee an absolutely perfect TFT display, and some panels may exhibit a certain number of
pixels that show an incorrect color. See the specifications on page 46 for more information.

If an image has fine striping (such as screen stripes), it may appear to flicker or display a moiré pattern.
Do not apply excessive pressure on the display surface, it may cause the appearance of a moiré or pooling

pattern. If this occurs, use less pressure on the display screen when working with the pen.
When a still image is displayed for a long period of time, an after-image may remain for a short time.

To prevent this, Wacom recommends using a screen saver or other power management feature.

IMPORTANT: To extend the life of the backlight, set your computer’s power management to
turn off the display when it is not in use for extended periods of time.

SOFTWARE INSTALLATION

IMPORTANT: You MUST install the Wacom pen tablet driver software for correct pen-on-

screen functionality.

To install the tablet software:

• Save your work and close all open applications. Temporarily disable any virus protection

programs.

• Insert the Wacom Pen Tablet Driver CD into your computer’s CD-ROM drive. If the software

installer menu does not automatically display, double-click on the Install icon located on the CD.

• Click on the INSTALL TABLET link and follow the prompts to install the driver software.

• Reactivate your virus protection program.

• After completing the software installation, make sure you can use your pen on the DTU-1931

display to move the screen cursor.
When you place the pen tip on the display screen, the screen cursor should immediately jump

to a corresponding position approximately beneath the pen tip. Lift the pen tip and place it on
the display screen surface in a different location – the screen cursor should again jump to the
new position. This is known as absolute positioning, and enables you to position the screen
cursor without having to drag your pen across the display screen surface.

• Be sure to check the Read Me file for updated information. If you have trouble installing the

DTU-1931, see the Troubleshooting section beginning on page 29.

Notes:

Driver installation automatically activates the new pen input functions available within Microsoft Windows
Vista and Office 2007 (except for Windows Vista Home Basic). Visit the Wacom web site at
www.wacom-asia.com/vista for additional information on using your Wacom pen in Windows Vista.

User-specific preferences are supported. After logging in, each user can customize their personal settings
in the Wacom Tablet control panel. Switching to another user will automatically load the settings for that
user.

To uninstall the tablet driver
If the pen display tablet does not respond properly or you lose cursor control, the tablet preferences may

be corrupted. You can delete the current preference settings and return the tablet to its factory default
condition. On a Windows system, run the TABLET PREFERENCE FILE UTILITY. Access the utility by clicking
on the Windows
P

REFERENCE FILE UTILITY.

START icon and selecting ALL PROGRAMS. Then select WACOM TABLET and TABLET

Page 17

WORKING WITH YOUR DTU-1931

As you work with the DTU-1931 pen display you can rest your hand lightly on the display screen,
just as if it were a drawing board or sheet of paper.

Because the DTU-1931 surface will be a little higher than your desk, consider adjusting the height of
your desk or chair to assure comfortable use of the device.

SETTING UP YOUR WORK AREA

To minimize fatigue, organize your work area so you can work comfortably. Position your
DTU-1931, the pen, and your keyboard for easy access without unnecessary reaching. The pen
display and any other displays should be positioned so you can view them comfortably with a
minimum of eyestrain.

• Take short breaks between tasks to stretch and relax your muscles.

• Use a gentle grip when working with the pen.

• Alternate tasks throughout the day.

• Maintain a good posture at all times. Minimize awkward postures and repetitive movements

that cause discomfort.

• Change your position if you feel any discomfort due to your work position.

Note: Wacom makes no representation, promise or guarantee that Wacom products will cure or prevent, in
whole or in part, mouse-induced repetitive stress symptoms, injuries or conditions. Individual results may
vary. Always obtain competent medical advice to determine the most appropriate treatment for your
specific situation.

Tips:

Be careful that you do not pull the cables out of their connections by accidentally moving the DTU-1931
too far from the computer.

The pen tether can be used to ensure your pen stays with your pen display tablet. Simply loop one end of
the tether through the tether hole located on the pen (if so equipped), and the other end of the tether
through the tether connection point located on the left or right side of the tablet.

The DTU-1931 can also be mounted to articulated arms or other third-party stands meeting the VESA 100
specification for display stands. For details, see Using an alternate mount or stand on page 42.

Working with your DTU-1931
Page 18

USING THE PEN

Eraser: When equipped and the eraser is brought within 5 mm (0.2 inch)

of the display, the tablet reports the pen location. Pressure information is
reported as you press down on the eraser. By default, the eraser function
is set to E

RASE.

Some non-eraser pens may be configured with a pen tether connection
point.

DuoSwitch (side switch): When equipped, make sure
the programmable switch is in a convenient location
where you can toggle it with your thumb or forefinger but
not accidentally press it while writing or drawing. You can
use the switch whenever the pen tip is within 5 mm
(0.2 inch) of the display screen surface; you do not need
to touch the pen tip to the display surface. Toggle the
switch in either direction to activate the button functions.

By default, the upper switch is set to D

OUBLE CLICK and

the lower switch is set to RIGHT CLICK.

Pen tip (replaceable nib): The pen is activated as soon
as it is brought within 5 mm (0.2 inch) of the pen display
screen. This allows you to position the screen cursor
without touching the pen tip to the display screen.

When pressure is applied to the pen tip, the pen
simulates a primary mouse button click. The tip click
pressure can be adjusted in the Wacom Tablet control
panel.

Notes:

When the pen is not in use, place it in the pen storage compartment, or lay it flat on your desk.
To maintain the sensitivity of your pen, do not store the pen in a container where it will rest on its tip.

Some product configurations may come with a pen that has no DuoSwitch or eraser. In that case, you
can ignore all explanations within this guide regarding the side switch or eraser.

The pen is cordless, battery-free, and senses the amount of pressure you apply to the tip. Hold the
pen like you would a normal pen or pencil. As you work with the DTU-1931, you can rest your hand
lightly on the display screen, just as if it were a drawing board or sheet of paper. You can tilt the pen
in any way that feels most comfortable for drawing.

PEN COMPONENTS

IMPORTANT: Use only the pen that came with your DTU-1931 pen display. Other pens

may not function properly. Also, the DTU-1931 pen tip is specifically designed for use with
the DTU-1931 pen display – the tips on other pens could damage the protective coating on
the pen display screen.

For information on customizing the pen settings, see Customizing on page 22.

BASIC PEN OPERATIONS

Pointing and selecting: Move the pen slightly above the DTU-1931

display screen to position the screen cursor; you do not need to touch
the display surface. The cursor jumps to the location where you place
the pen. Press the pen tip on the display screen to make a selection.

Note: You must calibrate the pen display tablet to correctly align the screen
cursor with the pen tip. (See Calibrating the DTU-1931 on page 24.) If the
screen cursor does not jump to a position close to the pen tip when you place
the pen on the display screen, then the pen tablet driver may not be installed or
is not loading. Install the pen tablet driver software if necessary. Otherwise,
see Troubleshooting, beginning on page 29.

Clicking: Tap the display screen once with the pen tip, or touch the
pen to the display screen with enough pressure to register a click.

Windows tip: To make navigating with the pen easier, configure Windows to
select when the pen is over an icon and to launch the icon with a single click.
To turn on this feature, first open a folder.

Double-clicking: Press the upper side switch, or
quickly tap the display screen twice in the same place
with the pen tip.
Double-clicking is easier when the pen is
perpendicular to the tablet screen. See the electronic
Software User’s Manual for information on fine-tuning
the double-click area.

Using the side switch: The pen may be equipped with a DuoSwitch. This switch has two
programmable functions that can be selected by rocking the switch in either direction. You can use
the DuoSwitch whenever the pen tip is within 5 mm (0.2 inch) of the display screen surface; you do
not need to touch the pen tip to the display surface in order to use the switch. By default, the upper
switch is set to D

OUBLE CLICK, and the lower switch is set to RIGHT CLICK.

Drawing and writing with pressure sensitivity: The pen responds to the nuance and inflection of
your hand movements, enabling you to create natural-looking pen and brush strokes within
applications that support this feature. To draw and write with pressure, select a pressure-sensitive
tool from your application’s tool palette. As you work on the screen surface, use various amounts of
downward pressure on the tip of the pen. Press lightly for thin lines or softer color. Press harder for
thick lines or dense color.

Erasing: In supporting applications, the pen’s eraser works like the
eraser on a pencil. In text applications, use the eraser to select text,
then lift the eraser from the tablet to delete the text.

2. If there is no display:

• Make sure that your computer is turned on. The power LED will light blue when the proper

video signal is received. It will glow orange if there is no video signal or if the computer is in
a power saving mode.

• Verify that the DTU-1931 is connected to an active VGA or DVI connector and that the

DVI/VGA switch is set to the correct video setting.

• Check that your video card has been properly installed and is functional. If you have

another display that is compatible with your video card, you can connect that display to the
card in order to verify that the video card is operating correctly.

3. Verify that the tablet and pen are working:

• Press the pen tip against the display and verify that the status LED lights blue.

• If the LED does not light, verify that the DTU-1931’s USB cable is plugged into an active

USB port. If the DTU-1931 is plugged into a USB hub, try plugging it directly into the USB
port on your computer.

• Be sure that the USB port to which you are connecting has not been disabled. It may be

necessary to check your system BIOS setting to verify that you have connected the
DTU-1931 to an active USB port.

• The status LED will light blue when the DTU-1931 is registered as a USB device and the

pen tip is pressed against the display.

4. Check the pen. If you cannot make a selection on the display screen with the pen:

• Test the pen by pressing the pen tip or eraser (when equipped) against the surface of the

pen display tablet. The tablet status LED should light blue.

• Now, without applying pressure to the pen tip but keeping the pen within 5 mm (0.2 inch) of

the pen display tablet surface, press the side switch (when equipped). The status LED
should again light blue.

• If the status LED does not light blue for these tests, be sure you are using the correct pen

that came with your DTU-1931.

• See Testing your pen on page 31 for detailed information.

If you are still having problems, you may have a defective pen or pen display.

To remove the old nib:

Clasp it with a Wacom nib removal tool,
pair of tweezers, needle-nosed pliers, or
similar instrument and pull the old nib
straight out of the pen.

To insert a new nib:

Slide it straight into the barrel of the pen.
Firmly push the nib until it stops. The new
nib will slide into the correct position.

ARNING

Prevent children from swallowing the pen nib or side switch. The pen nib or side switch may accidentally

be pulled out if children are biting on them.

Replace the pen nib when it gets too short –
less than 1 mm (0.04 inch).

CARING FOR THE DTU-1931

Keep the pen and the DTU-1931 LCD screen surface clean. Dust and dirt particles can stick to the
pen and cause excessive wear to the display screen surface. Regular cleaning will help prolong the
life of your LCD screen surface and pen.

Keep the DTU-1931 and pen in a clean, dry place and avoid extremes in temperature.
Room temperature is best. The DTU-1931 and pen are not made to come apart. Taking apart the
product will void your warranty.

IMPORTANT: Take care to never spill liquids onto the pen display or pen. Be especially
careful of getting the display, or pen buttons and tip wet – they contain sensitive electronic
parts that will fail if liquids enter them.

CLEANING

To clean the DTU-1931 casing or the pen, use a soft, damp cloth; you can also dampen the cloth
using a very mild soap diluted with water. Do not use paint thinner, benzine, alcohol, or other
solvents to clean the unit casing or pen.

To clean the display screen
only a light amount of pressure to the display screen and do not make the surface wet. Do not use
detergent to clean the display screen; this may damage the coating on the screen. Please note that
damage of this kind is not covered by the manufacturer’s warranty.

REPLACING THE PEN TIP

The pen tip (nib) will wear with normal use. Excessive pressure will cause it to wear sooner. A worn
nib may damage the coating on the DTU-1931 display screen. To avoid this, periodic tip
replacement is recommended.

When the nib gets too short or develops a sharp edge, you can replace it with one of the extra nibs
that came with the pen.

, use an anti-static cloth or a slightly damp cloth. When cleaning, apply

IMPORTANT: When not in use, place the pen in the pen storage compartment, or lay it flat
on your desk. To maintain the sensitivity of your pen, do not store the tool in a container
where it will rest on its tip.

USING AN ALTERNATE MOUNT OR STAND

To remove the adjustable stand and
attach the pen display to a different
mounting platform:

1. Turn off your computer and power off
the DTU-1931. Then disconnect all
cables from between the unit and
your computer.

2. Protect the display screen surface by
spreading a soft cloth onto a flat
table and placing the DTU-1931 face
down on the cloth.

3. Remove the four screws and lift the
adjustable stand assembly away
from the body of the unit.

4. Using the appropriate screws for
your mounting platform, firmly attach
the DTU-1931 to the alternate
mounting platform.

5. Refer to the Installation instructions,
beginning on page 11, and reattach
the cabling.

CAUTION

When attaching the DTU-1931 onto an alternate
mounting platform, be sure to follow all instructions
in the documentation supplied by the platform
manufacturer. If improperly installed, the unit could
fall, resulting in damage to the unit or physical injury.

If you will be using the DTU-1931 in an installation that requires the use of an alternate mounting
platform, you can remove the adjustable stand from the unit and mount the pen display onto any
mount arm or stand conforming to the VESA 100 mm standard.

Mounting screws that are 4 mm wide with a 0.7 mm pitch (M4 Regular), with a screw clearance
depth of 15 mm are required. Exceeding the clearance depth of 15 mm will damage the pen display
internal components.
