Section 4: Operation
Power
The touchscreen display ships in an ON state.
Toturn the touchscreen display on or off, press the touchscreen display power button on the OSD
controller once. The power status LED on the OSD controller functions according to the following
table.
Touchscreen Display/Computer Module Status LED Status
OFF OFF
SLEEP PULSING
ON ON
The system consumes low power when in SLEEP and OFF modes. For detailed power consumption
specifications, refer to technical specifications on the Elo website http://www.elotouch.com
Touching the screen will bring the attached host PC out of SLEEP mode (similar to moving the mouse or pressing a keyboard key).
To improve reliability and reduce wasteful power consumption, disconnect the AC power cable from the monitor when long periods of disuse are planned.
Touch
Your touchscreen display is factory-calibrated and should not need manual calibration (unless the input video is
not fully scaled to the native resolution, or the touch experience needs to be calibrated to a specific user).

User Manual: 90 Series RevB
UM600129 Rev E, page 10 of 28
IntelliTouch Dual Touch Technology
When connected to Windows 7, 8.1 and 10 or later computers, the touchscreen display can
report 2 simultaneous touches. When connected to Windows XP computers, the touchscreen
display reports single touch.
The IntelliTouch Dual Touch touchscreen can be re-calibrated to your displayed video
image, if needed, through the calibration function in the Elo driver controlpanel.
The IntelliTouch Dual Touch driver will only support multiple monitors if
they are all using the IntelliTouch Dual Touch technology.
Touse multiple IntelliTouch Dual Touch monitors, double click on the
EloConfig desktop shortcut to open up the Elo Touch Configuration
screen
Select “Match Touch to Display...” to calibrate multiple monitors.
Projected Capacitive Touch Technology
When connected to Windows 7,8.1 and 10 or later computers, the touchscreen display can report 10 simultaneous touches.
When connected to Windows XP computers, the touchscreen display reports single touch.
No additional drivers are required for this technology to work with Windows 7, 8.1 and 10 or later, it uses Windows HID drivers.
Refer to Chapter 2, Section “Installing the Touch Technology Software Drivers” to find instructions to download touch drivers for
Windows XP.
Gesture Support
The IntelliTouch Dual Touch technology enables several gestures that support single and multiple touches. Refer to the
Microsoft Website http://msdn.microsoft.com/en-us/library/dd940543 on the various gestures that are supported in Windows 7.
Video
A display’s native resolution is its width and height measured in number of pixels. Generally, for best performance, an image

User Manual: 90 Series RevB
UM600129 Rev E, page 11 of 28
displayed on this monitor will look best when your computer’s output resolution matches this monitor’s native resolution.
For computer output resolutions at non-native resolutions, the monitor will scale the video to its panel’s native resolution. This involves
stretching or compressing the input image as needed in the X- and Y-dimensions to fit the display’s native resolution.An unavoidable byproduct
of the scaling algorithms is a loss of fidelity when the computer’s output video image is scaled by the monitor to fit the display. This loss of
fidelity is most apparent when viewing feature-rich images at close distances (for example images containing small-font text).
Your touchscreen display will likely not require video adjustments. However, for analog VGA video, variations in video graphic card outputs may require
user adjustments through the OSD to optimize the quality of the monitor’s displayed image. These adjustments are “remembered” by the touchscreen
display. Also, to reduce the need for adjustments for different video mode timings, the monitor correctly scales and displays some of the video
industry’s most common video timing modes. Refer to the technical specifications for this monitor at http://www.elotouch.com for a list of these Preset
VideoModes.
On-Screen Display (OSD)
Four OSD buttons are located on a wired control box. These can be usedto
adjust various display parameters. The buttons and their functionality are:

All touchscreen display adjustments made through the OSD are automatically memorized as soon as they are entered.
This feature saves you from having to reset your choices every time the touchscreen display is unplugged or powered off
and on. If there is a power failure, the touchscreen display settings will not default to the factory specifications.
OSD and Power Lockouts
Press and hold the “Menu” and “Down” buttons for two seconds to enable/disable the OSD Locking feature. When the OSD
Locking is enabled, pressing any of the Menu, Up, Down, or Select keys will have no effect on the system.
Press and hold the “Menu” and “Up” buttons for two seconds to enable/disable the Power Locking feature. When
the Power Locking is enabled, pressing the power switch will have no effect on the system.
Temperature Control for 95/96 Series only
The monitor contains a temperature sensor that provides the user with real-time temperature readings. This reading can be found by opening the OSD menu:
Information ►System Temperature. If the monitor is operated above the operating temperature limit, the monitor will go into “Thermal Protection Mode.” This
mode will reduce the backlight brightness to bring the internal temperature back within operating range. While in this mode, brightness cannot be increased
beyond the set value. If the internal temperature decreases below the Thermal Protection Mode temperature for at least five minutes, normal operation is
resumed.
When the Thermal Protection Mode is enabled, the following icon will appear in the Main Menu. This will indicate that the Thermal Protection Mode is active.
Icon showing that Thermal Protection Mode is active
If the monitor continues to be operated above the operating temperature limit, the user will be prompted to shut off the monitor within sixty seconds. If the
system is not manually turned off within sixty seconds, the touchmonitor will automatically turn off to prevent permanent damage to the monitor.
