WRONG OR ABNORMAL COLORS
•Flip the Power switch ON. The Power LED turns on.
•Make sure the A/C power cord is securely connected to the power jack and to a power outlet.
•Plug another electrical device (like a radio) into the power outlet to verify that the power outlet is supplying the proper voltage.
•Make sure the video cable attached from the monitor is tightly secured to the video output port on the back of the computer.
•Adjust the brightness and contrast.
•Not enough power is being supplied to the LCD monitor. Connect the LCD monitor to a different outlet. If a surge protector is being used, there may be too many devices plugged in.
•See Timing Guide Section of this manual with a list of refresh rates and frequency settings showing the recommended setting for the LCD monitor.
•If any colors (red, green or blue) are missing, check the video cable to make sure it is securely con- nected. Loose pins in the cable connector could cause a bad connection.
•Connect the LCD monitor to another computer.
•Check the graphics card for proper sync scheme (or sync polarities) to match the LCD monitor’s specifica- tions.
