Troubleshooting
No power
• If your monitor has a
rear Main Power switch, make sure it is ON. For all
monitors: make sure front Power button (or switch) is ON. NOTE: when
shipped from factory, each monitor with a rear Main Power switch is set to OFF.
• Make sure A/C power cord is securely connected to back of monitor and to
a power outlet.
• Plug another electrical device (like a radio) into power outlet to verify that
outlet is supplying proper voltage.
Power on but no screen image
• Make sure video cable supplied with monitor is tightly secured to video
output port on back of computer. If other end of video cable is not attached
permanently to monitor, tightly secure it to monitor.
• Adjust brightness and contrast.
• Check this user's guide to see if an adapter is required for proper signal
continuity between graphics card and monitor.
Flickering
• Not enough power supplied. Connect monitor to different outlet. If using
surge protector, reduce number of devices plugged in.
• Check ViewMeter
®
to verify refresh rate (vertical frequency) is 75 Hz or
higher. See Specifications on page 13.
• Make sure graphics card in your computer can use non-interlaced mode at
desired frequencies. To enable your graphics card to support higher refresh
rates, try selecting fewer colors or running lower resolutions.
• Remove any devices from area around monitor that emit magnetic fields
such as radios, surge protectors, unshielded speakers, fluorescent lights,
AC power converters, desk fans, etc.
Wrong or abnormal colors
• If any colors (red, green, or blue) are missing, check video cable to make
sure it is securely connected. Loose or broken pins in the cable connector
could cause a bad connection.
• Connect monitor to another computer.
• Turn monitor OFF, wait one minute, then turn ON again.
Do this only once.
• If you have an older graphics card, contact Optiquest
®
Customer Support
for a non-DDC adapter.

range. (See Input Signal/Sync in the
Specifications
section).
