The IntelliTouch touchscreen can be re-calibrated to your displayed video image, if needed,
through the Calibration function in the Elo driver control panel.
When connected to Windows 7 computers, the touchmonitor can report 4 simultaneous
touches.
When connected to Windows XP computers, the touchmonitor reports single touches.
No additional drivers are required for this technology to work, it uses Windows HID drivers.
No calibration is required for this technology.
An LCD panel’s native resolution is its width and height measured in number of pixels.
In almost all cases, an image displayed on an LCD monitor will look best when your computer’s
output resolution matches the LCD panel’s native resolution. See the display specifications on
the Elo website www.elotouch.com to find your touchmonitor’s native resolution. Operating in
other resolutions will degrade video performance.
For computer output resolutions at non-native resolutions, the monitor will scale the video to its
panel’s native resolution. For smaller input video resolutions, this involves “stretching” the
input image in the X- and Y-dimensions to fit the panel. For larger input video resolutions, this
involves “compressing” the input image in the X- and Y-dimensions to fit the panel. 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).
For full APR touch functionality, the input video image should be fully scaled to the display’s
native resolution.
Your Touchmonitor will likely not require video adjustments. However, for analog VGA video,
variations in video graphic card outputs may require touchmonitor adjustments through the
OSD to optimize the quality of the touchmonitor’s displayed image. 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.
