Projected Capacitive Touch Technology
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.
Gesture Support
The iTouch Plus and Projected Capacitive touch technologies enable 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 displayed on this monitor will look best when your computer’s
output resolution matches this monitor’s native resolution of 1280 x 1024.
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 touchmonitor 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 touchmonitor’s displayed image. These adjustments are
“remembered” by the touchmonitor. 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 Video Modes.
