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 37.
If your color is not uniform, degauss the touchmonitor as
described in Chapter 3, page 18, 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.
Verify that your video display adapter settings are
formatted for the correct resolution and vertical refresh
rates.
