Connecting the Display
1 Connect all cables to the computer first. This would include the VGA cable and the optional
RS 232 serial or usb touch screen connection.
2 After connecting the cables between the LCD monitor and the computer, plug the customer
supplied 120VAC source to the 120VAC connection on the rear.
3 Once the 120VAC connection is made and switched on, the display is active.
4 If your computer was off, turn on your computer.
5 Your display should now operate as a normal computer display showing your OS or the video
that is being sent to the flat panel.
Note: If for any reason the display goes blank and gives a
n “Out of Range” or “No Input Signal”,
your computer or video source is putting out a signal that is out of range of the LCD’s video
board. If this happens, reboot the computer or video source and make sure you are inputting the
correct signal. If the disp
lay doesn’t work properly, it may be because:
(a) The resolution is too high or low for the LCD.
(b) The refresh rate is set too high. Refresh on an LCD is different than a CRT. Set the refresh
to 60Hz. CRT’s need a high refresh rate to avoid flicker. The refresh rate has no impact on
LCD’s.
(c) The power source is incorrect.
(d) The unit is malfunctioning. If you believe this to be true, disconnect the video cable from
the rear of the LCD and connect to a known good computer CRT display. If the computer
display is working satisfactory and the video is within the appropriate range, then contact
Vartech Customer service for a RMA number at 800-223-8050.
