About Touchmonitor Adjustments
Your touchmonitor probably does 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 at 1440 X 900
resolution, at 56–76
Hz refresh 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
ordinarily allows you to change monitor settings, is then disabled.
Note: Do not operate the touchmonitor if you see the OOR mes-
sage, or LCD damage may result. If you see the OOR message, set
the video mode to one within the allowable range.
