Troubleshooting

No picture

The signal cable should be completely connected to the display card/computer.

The display card should be completely seated in its slot.

Front Power Switch and computer power switch should be in the ON position.

Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)

Check the monitor and your display card with respect to compatibility and recommended settings.

Check the signal cable connector for bent or pushed-in pins.

If nothing is displayed on the screen when HDCP device is connected, reset the power of the device.

Power Button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

Image persistence

Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

NOTE:

As with all personal display devices, VIEWSONIC recommends displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

Image is unstable, unfocused or swimming is apparent

Signal cable should be completely attached to the computer.

Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine adjustment. When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.

Check the monitor and your display card with respect to compatibility and recommended signal timings.

If your text is garbled, change the video mode to non-interlace and use 60 Hz refresh rate.

Image of component signal is greenish

• Check to see if the DVD/HD input connector is selected.

LED on monitor is not lit (no green or red color can be seen)

Power Switch should be in the ON position and power cord should be connected.

Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).

RED LED on monitor is blinking

• A certain failure might have occurred, please contact your nearest authorized VIEWSONIC service facility.

Display image is not sized properly

Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.

Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)

Selected resolution is not displayed properly

Use OSD Display Mode to enter Information menu and confirm that the appropriate resolution has been selected. If not, select corresponding option.

No Sound

Check to see if speaker cable is properly connected.

Check to see if mute is activated.

Check to see if volume is set at minimum.

Remote Control is not available

Check the Remote Control’s batteries status.

Check if batteries are inserted correctly.

Check if the Remote Control is pointing at the monitor’s remote sensor.

“SCHEDULE”/“OFF TIMER” function is not working properly

The “SCHEDULE” function will be disabled when the “OFF TIMER” is set.

If the “OFF TIMER” function is enable and the power to the LCD monitor is turned off if the power supply is interrupted unexpectedly, then the “OFF TIMER” will be reset.

Stripe Noise

Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or degradation.

“NO SIGNAL” is displayed on the screen

Image may not be displayed right after HDCP device is connected.
