Display Setup and On Screen Display
Connect and secure cables to the display and the computer, except for the USB cable. The AC
cord set provided with your display should be appropriate for your region. If the proper cord set
has not been provided, you may use any cord set with an IEC320 connector at the appliance
end to connect to your touch display.
Notice: Unless your Preh MCI Touch Monitor has a serial data interface, or you are connecting
this MCI Touch Monitor to a computer that already has Preh touchscreen MSR and Customer
Display drivers installed, please leave the USB cable disconnected until the appropriate drivers
for your computer’s operating system have been installed.

Use the OSD buttons to set up the display:
1. Turn on the display with the POWER button.

of the display.

If your application requires use of the display at another resolution than 1024 x 768, such
as 800 x 600, you may achieve satisfactory operation by using the Auto Adjust procedure

the display. Access the OSD main menu and use the Video Adjustment functions (see table on
