method; you will not find a setup.exe file within the download.
2-16 Elo Entuitive Touchmonitor User Guide
Installing the Serial Touch Driver for MS-DOS and
Windows 3.1
You must have a DOS mouse driver (MOUSE.COM) installed for your mouse
if you wish to continue using your mouse along with your touchmonitor in
DOS.
To install Windows 3.x and MS-DOS from Windows 95/98, follow the
directions below:
1 Insert the Elo CD-ROM in your computer’s CD-ROM drive.
2 From DOS, type d:\EloDos_W31 to change to the correct directory on the
CD-ROM (your CD-ROM drive may be mapped to a different drive letter).
3 Type install and press Enter to start the installation.
4 Align the touchscreen.
You must have already completed Steps 1 and 2 before proceeding. Refer to
Chapter 2 of the Elo DOS and Windows Driver Guide as necessary for
additional installation information.
To run the INSTALL program:
1 Type INSTALL at the DOS prompt in the directory containing the driver
install files.
2 INSTALL asks you to select the software to install. Then choose
d:\EloDos_W31 from the displayed list.
3 INSTALL also asks you for the paths to use during installation, or you may
use its defaults. INSTALL creates directories as necessary, and warns you if
they exist.
If you are updating your software, you may wish to specify the paths containing
the earlier versions, and overwrite the obsolete files. All executable programs
are upward compatible. For a list of differences from each previous version of
the drivers, be sure to select "Differences from Previous Versions" during the
installation process.
INSTALL updates your AUTOEXEC.BAT file with the drivers you select.
INSTALL makes a copy of your original AUTOEXEC.BAT file, called
AUTOEXEC.OLD. If you already have Elo driver commands in your
AUTOEXEC.BAT file, they will be commented out.
When INSTALL is finished, it leaves a file called GO.BAT in the subdirectory
you specified. GO loads the touchscreen driver, runs the calibration program
ELOCALIB, and gives you some final instructions.
If you are using Windows 3.1, you will also calibrate the touchscreen within
Windows 3.1 with the Touchscreen Control Panel.

About Touchmonitor Adjustments
Your touchmonitor will unlikely require adjustment. Variations in video output
and application may require adjustments to your touchmonitor to optimize the
quality of the display.
For best performance, your touchmonitor should be operating in native
resolution, that is 1280 x 1024 at 60-75 Hz. Use the Display control panel in
Windows to choose 1280 x 1024 resolution.

ATIVE
The native resolution of a monitor is the resolution level at which the LCD
panel is designed to perform best. For the Elo LCD touchmonitor, the native
resolution is 1280 x 1024 for the SXGA-17 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 17" LCD
640x480 (VGA) Transforms input format to 1280x1024
800x600 (SVGA) Transforms input format to 1280x1024

R
ESOLUTION
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
SVGA
XGA
SXGA
UXGA
640x480
800x600
1024x768
1280x1024
1600x1200
A-25
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.
