About Touchmonitor Adjustments
Your touchmonitor most likely will not require adjustment. However,
variations in video output and application may require adjustments to
your touchmonitor to optimize the quality of the display.
For best performance, your video source should be 1680 X 1050
resolution, at 60Hz vertical frame rate. Operating in other resolutions
degrades video performance.
For input video outside the refresh rate and dot clock ranges, the
monitor does not automatically adjust, but displays an "Out of Range"
(OOR) message and the On-screen Display (OSD) menu, which ordi-
narily allows you to change monitor settings, is disabled.
Note: If the OOR message is displayed, do not continue to oper-
ate the touchmonitor or LCD damage may result. To enable the
touchmonitor, change the computer video mode so it is within
the allowable vertical frame rate range shown under "Input Video
Range" on page 32.
