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.
