Problem Suggestion (s)
No picture. 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).
Touchmonitor does not enter
power management mode. The video signal from the computer does not comply
with VESA DPMS standard. Either the computer or the
