Suggestion (s)
Your touchmonitor may not be getting power.
Make certain that your power strip is plugged into
the wall socket and that the PC and touchmonitor
are plugged in and powered on.
Test the power supply by trying different cables or
a different wall outlet, or by plugging another
appliance into the outlet.
The touchmonitor might be in standby mode. Push
one of the keyboard keys. Check that the keyboard
is properly connected to the computer.
Ensure that your computer and video card are
properly configured (consult the video card
documentation).
The video signal from the computer does not
comply with VESA DPMS standard. Either the
computer or the graphics adapter is not using the
VESA DPMS power management function.
The screen may seem to flicker when the refresh
rate is less than 75Hz. See the list of recommended
modes in Appendix C, page 27.
If your color is not uniform, degauss the
touchmonitor as described in Chapter 3, page 15,
and make sure that the touchmonitor is at least 12
inches from any other electrical equipment.
Make certain there is a good connection between
the touchmonitor and the computer.
Read about adjusting your touchmonitor picture
and make the appropriate adjustments.
Readjust your brightness and contrast settings.
