4 Operating the Monitor
Installing the Monitor Driver
The CD that comes with the monitor contains monitor driver files you can install on your computer:
● an .INF (Information) file
● an .ICM (Image Color Matching) file
PDF Complete is supplied on this CD and can be installed from the menu.
NOTE: If the monitor does not include a CD, the .INF and .ICM files can be downloaded from the HP
monitors support Web site. See Downloading from the Worldwide Web on page 11 in this chapter.
The Information File
The .INF file defines monitor resources used by Microsoft Windows operating systems to ensure monitor
compatibility with the computer’s graphics adapter.
This monitor is Microsoft Windows Plug and Play compatible and the monitor will work correctly without
installing the .INF file. Monitor Plug and Play compatibility requires that the computer’s graphic card is
VESA DDC2 compliant and that the monitor connects directly to the graphics card. Plug and Play does
not work through separate BNC type connectors or through distribution buffers/boxes.
The Image Color Matching File
The .ICM files are data files that are used in conjunction with graphics programs to provide consistent
color matching from monitor screen to printer, or from scanner to monitor screen. The .ICM file contains
a monitor color system profile. This file is activated from within graphics programs that support this
feature.
NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC)
Profile Format specification.
10 Chapter 4 Operating the Monitor ENWW

Touchscreen Tips
If you experience operational issues with the touchscreen system either during or after installation, use
the tips below to help you determine the source of the problem.
● If “No Elo touchmonitor found” is displayed on the screen, install the latest drivers. Touchmonitors
with the dual serial/USB interface require the latest drivers. If you are replacing an existing
installation and see this problem, you should update your touchscreen driver with one from the Elo
Web site Driver and File Downloads page.
● Be sure to calibrate the L5006tm touchscreen monitor. Touch response must be aligned to the
video image (this is sometimes called calibration). Normally this need only be done when the touch
drivers are initially installed.
NOTE: The L5009tm LCD with APR technology has a fixed coordinate system that never
changes over time, position or environmental changes. With APR, calibration is eliminated.
To calibrate the L5006tm touchscreen:
1. Click the Windows Start button.
2. Select Settings > Control Panel (on later operating systems the Settings step is omitted).
3. Open the Elo application by double-clicking the Elo icon.
On Windows XP it may be necessary to click the Show Classic View button on the left side of the
screen to see the Elo icon.
4. Click the Alignment/Calibration button.
The Alignment/Calibration button is always on the General tab of the Elo Control Panel tab set. It
may be titled Calibrate, Align or it may just be an icon (fingers and cross marks on a display).
5. Touch the target that is displayed in the upper left corner. The target will reappear in the lower right
corner.
6. Touch the lower right target. The target will reappear in the upper right corner.
7. Touch the upper right target. The next screen is an alignment check.
8. On the alignment check screen, touch various places on the screen and see that the cursor jumps
to the point of touch.
A progress bar displays the relative time remaining before the routine will time out; if time-out is
reached, the routine is aborted and the new alignment points are not retained.
If response is correct, touch the Accept button - it may be a Yes button or a green check.

ENWW Touchscreen Tips 17
Page: 23
If the touchscreen is not responding to touch, check your serial or USB connection by doing the following:
● Serial Connection - Run the comdump diagnostic utility to determine if the touchscreen, the serial
touch controller, the computer's serial COM port and the associated cabling are connected and
functioning properly. Download the latest version of comdump.exe (7K) from the Elo Web site
Driver and Files Download page. You should save the file where it can be accessed easily - either
to a floppy or to the root of your hard drive. Comdump is a DOS application, so if you are running
one of the Windows operating systems you must either boot to a DOS boot diskette or disable the
driver so you can access the COM port from a command prompt.
● USB Connection - If the Human Interface Device (HID) is not listed in Device Manager after a USB
touchmonitor is connected, check to determine if a file named mouhid.sys is in the \windows (or
winnt) \system32\drivers folder.
◦ The file will be missing if a USB mouse has never been connected to the system.
◦ If the file is not there, connect a USB mouse to the system or copy mouhid.sys from another
system.
◦ Once mouhid.sys is in the proper location, remove and reinstall the touch drivers.
If you have determined that the HID files are missing or corrupted ("Error installing mouse" when
installing the HID drivers, and also a yellow "!" in Device Manager under Mouse), check that all of
the following files are present in the \\winnt\system32\drivers folder:
◦ Hidusb.sys
◦ Hidclass.sys
◦ Hidparse.sys
◦ Mouhid.sys
If all the files are there, try replacing them with the same files from a known good system. It is
suggested that you save the original files in a backup directory.
The touch can not be held longer than 10 seconds. IntelliTouch controllers have a built-in two minute
untouch time-out. By default, the 4.20 Universal driver generates an untouch after 10 seconds of
constant touch. The untouch time-out can be changed by modifying a registry key. This time-out will
override any registry time-out value if the registry value exceeds 120 seconds (120000 milliseconds).
To change the time-out time:
1. Run regedit or regedt32 (click Start > Run, enter regedit).
2. Drill down to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Enum.
a. For serial controllers: SERENUM > ELOSERIAL > ******* > Device Parameters.
b. For USB controllers: HID > VID_04e7 > ******** > ***************** > Device Parameters.
NOTE: The "******" entries are id numbers used by the Windows operating system.
3. Double-click the UntouchTimeOut key. The Edit DWORD Value dialog box opens.
4. Click the Decimal radio button. Value displays in decimal (default: 10000).
5. Enter the delay time in milliseconds, 60000 is 60 seconds.
18 Appendix A Troubleshooting ENWW
Page: 24
6. Exit regedit when done.
7. Shut Down and restart the machine. A restart is required before the setting will take effect.
A cursor is not visible. To make the cursor visible, first, open Control Panel > Elo Touchscreen >
Mode tab. Check if the Hide arrow mouse pointer box is checked; if yes, un-check it and click OK. If a
mouse is not installed on the computer, Shut Down the computer, install a mouse, then restart the
computer. The cursor should now be visible. You may then Shut Down and remove the mouse, or leave
it connected, as desired.
If connecting multiple monitor systems, all monitors must be configured to have independent resolution
control (as in two monitors, each at 1024 x 786 resolution), rather than a single, large desktop (as in
2048 x 768). Multiple individual video cards are automatically set up as individual monitors. Some
multiport video cards can be configured either way; in this case, the video driver must be set up properly.
Once the multiport video has been properly configured, the Elo Universal driver should be removed and
reinstalled. Some multiport video cards can only be configured as a single large desktop, and they will
not work with Elo's multiple monitor driver setup.

Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
● You are not using a standard graphics adapter.
● You are not using a preset mode.
If this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these modes and saved in memory. The monitor
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In
addition to the 15 factory preset, there are 7 user modes that can be entered and stored.
The only condition to store as a user mode is the new display information must have 1 KHz difference
for horizontal frequency or 1 Hz for vertical frequency or the sync signal polarities are different from the
default modes.

Energy Saver Feature
When the monitor is in its normal operating mode, the monitor uses less than 21 watts and the Power
light is green.
The monitor also supports a reduced power state. The reduced power state will be entered into if the
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and
the power light is turned amber. When the monitor is in the reduced power state, the monitor will utilize
less than 2 watts of power. There is a brief warm up period before the monitor will return to its normal
operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called power
management features).
NOTE: The above power saver feature only works when connected to computers that have energy
saver features.
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to enter
into the reduced poser state at a predetermined time. When the monitor's Energy Saver utility causes
the monitor to enter the reduced power state, the power light blinks amber.

D Native Resolution
The native resolution of a monitor is the resolution level at which the LCD panel is designed to perform
best. The native resolution is 1024 x 768 for the 15 inch size. In almost all cases, screen images look
best when viewed at their native resolution. You can lower the resolution setting of a monitor but not
increase it.
Input Video 15” LCD
640 x 480 (VGA\S) Transforms input format to 1024 x 768
800 x 600 (SVGA) Transforms input format to 1024 x 768
1024 x 768 (XGA) Displays in Native Resolution
The native resolution of an LCD is the actual number of pixels horizontally in the LCD by the number of
pixels vertically in the LCD. LCD resolution is usually represented by the following symbols:
VGA 640 x 480
SVGA 800 x 600
XGA 1024 x 768
SXGA 1280 x 1024
UXGA 1600 x 1200
As an example, a SVGA resolution LCD panel has 800 pixels horizontally by 600 pixels vertically. Input
video is also represented by the same terms. XGA input video has a format of 1024 pixels horizontally
by 768 pixels vertically. When the input pixels contained in the video input format match the native
resolution of the panel, there is a one to one correspondence of mapping of input video pixels to LCD
pixels. As an example, the pixel in column 45 and row 26 of the input video is in column 45 and row 26
of the LCD. For the case when the input video is at a lower resolution than the native resolution of the
LCD, the direct correspondence between the video pixels and the LCD pixels is lost. The LCD controller
can compute the correspondence between video pixels and LCD pixels using algorithms contained on
its controller. The accuracy of the algorithms determines the fidelity of conversion of video pixels to LCD
pixels. Poor fidelity conversion can result in artifacts in the LCD displayed image such as varying width
characters.
