Troubleshooting

No power

• Make sure power button (or switch) is ON.

• Make sure A/C power cord is securely connected to the back of the monitor

and to a power outlet.

• Plug another electrical device (like a radio) into the power outlet to verify that

the outlet is supplying proper voltage.

Power is ON but no screen image

• Make sure the video cable supplied with the monitor is tightly secured to the

video output port on the back of the computer. If the other end of the video cable

is not attached permanently to the monitor, tightly secure it to the monitor.

• Adjust brightness and contrast.

•

NOTE:

Macintosh users may need an adapter. Contact Customer Support for

more information.

Flickering

• Not enough power supplied. Connect the monitor to a different outlet. If

using a surge protector, reduce the number of devices plugged in.

• Check the ViewMeter

from the main menu to verify the refresh rate (vertical

frequency) is 75 Hz or higher. See

Specifications

on page 10.

• Remove any devices from the area around the monitor that emit magnetic

fields such as radios, surge protectors, unshielded speakers, fluorescent

lights, AC power converters, desk fans, etc.

• Make sure the graphics card in your computer can use non-interlaced mode at

the desired frequencies. To enable your graphics card to support higher

refresh rates, try selecting fewer colors or running lower resolutions.

Wrong or abnormal colors

• If any colors (red, green, or blue) are missing, check the video cable to make

sure it is securely connected. Loose or broken pins in the cable connector

could cause an improper connection.

• Connect the monitor to another computer.

• Select Degauss from the Main Menu. Do this only once.

• If you have an older graphics card, contact ViewSonic

Customer Support.

Entire screen image rolls vertically

• Make sure video input signals are within the monitor's specified frequency range.

• Try the monitor with another power source, graphics card, or computer system.

• Connect the video cable securely.

Control buttons do not work

• Press only one button at a time.
