Self-Test Mode

NOTE: The PWR SAVE DELAY setting in the Option OSD controls how long the color bar pattern remains on the screen. The settings are for 5 seconds, 60 seconds, 60 minutes, and OFF; if PWR SAVE DELAY is set to OFF, the color bar pattern remains on the screen indefinitely. If you press and hold the RESET button on the monitor for 5 seconds, PWR SAVE DELAY is automatically set to 60 seconds.

To ensure that the self-test works correctly, press and hold the RESET button on the monitor for 5 seconds.
Turn off the monitor and disconnect the video cable from the computer system.
Turn on the monitor and wait a few seconds.
A color bar pattern appears, as shown in the following illustration. The pattern remains stationary and stays on for 60 seconds, and the LED on the front of the monitor remains orange.

If the monitor displays the color bar pattern, the monitor is functioning properly.

Power-Saving Function

NOTES: If the PWR SAVE DELAY setting in the Option OSD is set to OFF, the monitor never enters power-save mode. Make sure that PWR SAVE DELAY is not set to OFF; Dell recommends that you use the 5 SEC setting when you are using the power-saving function.

The self-test mode color bar pattern appears before the monitor enters power-save mode. If PWR SAVE DELAY is set to OFF, the monitor never enters power-save mode and the color bar pattern remains on.

The power-saving function has the following default settings:

Power Consumption Mode	Power Consumption	Recovery Time	Indicator
Normal on	< 160 W	—	Green
Standby (1st mode)	< 100 W	Approximately 3 seconds	Green and orange alternate
Suspend (2nd mode)	< 15 W	Approximately 3 seconds	Green and orange alternate
Active off (3rd mode)	< 5 W	Approximately 10 seconds	Orange
Power off	0 W	—	Off
Failure mode	—	—	Orange flashes

Degaussing the Monitor

Turn power to the monitor off and then on to auto-degauss the monitor. Before degaussing a second time, wait a minimum of 20 minutes (for best results). This monitor is equipped with a manual degauss button. To degauss the monitor, enter the Option OSD menu.

Plug and Play Capabilities

This monitor complies with VESA Display Data Channel (DDC) standards, which support Plug and Play features that simplify monitor installation. DDC technology provides a mechanism for the video subsystem firmware and operating system to automatically determine the capabilities of the attached monitor, and configures the monitor's operating parameters accordingly. If your computer does not support this standard, you can still use the monitor with your computer, but you may need to specify manually the proper display resolution.

Troubleshooting

Symptom	Possible Solution
The power indicator is not lit.	Make sure the power cord is properly connected. Make sure the power switch is in the On position.
The `no input signal` message appears, or the power indicator is either orange or alternating between green and orange.	Press any key on the computer keyboard. Make sure your computer is turned on. Make sure the video signal cable is properly connected and all plugs are firmly seated in their sockets. Make sure none of the HD15 video-input connector pins are bent or pushed in. Make sure the video board is completly seated in the proper bus slot.
The `out of scan range` message appears.	Make sure the video frequency range is within that specified for the monitor. If you are using a video signal cable adapter, make sure it is the correct type.
No message is displayed, and the power indicator is green or flashing orange.	Run the self-test function. Make sure none of the HD15 video input connector pins are bent or pushed in.
Picture is scrambled.	Make sure your system's graphics mode and video frequency are supported by this monitor. Even within the proper range, some video boards may have a sync pulse that is too narrow for the monitor to synchronize with correctly.
Color is not uniform.	Turn power to the monitor off, then on to auto-degauss the monitor. Before degaussing a second time, wait a minimum of 20 minutes (for best results).
You cannot adjust the monitor with the buttons on the front panel.	If the Control Lock function is set to On, set it to Off using the Option OSD.
Screen image is not centered or sized properly.	Adjust the size or centering. Some video modes do not fill the screen to the edges. This problem tends to occur with certain video boards.
Edges of the image are curved.	Adjust the geometry using the Geometry OSD.
White lines show red or blue shadows at edges.	Adjust the convergence using the Screen OSD.
Picture is fuzzy.	Adjust the contrast or brightness. Degauss the monitor using the Option OSD. If red or blue shadows appear along the edges of the images, adjust the convergence using the Screen OSD. If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation effect using the Screen OSD.
Picture bounces or has wavy oscillations.	Isolate and eliminate any potential sources of electric or magnetic fields. Common causes for this symptom are electric fans, fluorescent lighting, and laser printers. If another monitor is positioned close to this monitor, increase the distance between them to reduce the interference. Plug the monitor into a different AC outlet, preferably on a different circuit. Use the monitor with a different computer in a different room.
Picture is flickering.	Refer to your computer system's user's guide, and change your display refresh rate settings so they match the monitor's capabilities.
Picture appears to be ghosting.	Eliminate the use of video cable extensions and/or video switch boxes. Excessive cable length or a weak connection can produce this symptom.
Wavy or elliptical (moire) pattern is visible.	Cancel the moire using the Screen OSD. Due to the relationship between resolution, monitor dot pitch, and the pitch of some image patterns, certain screen backgrounds sometimes show moire. Change your desktop pattern.
Two fine horizontal lines (wires) are visible.	These damper wires stabilize the vertically striped aperture grille. This aperture grille allows more light to pass through to the screen, giving the Trinitron CRT more color and brightness. This is not a malfunction.
A humming noise is heard right after the power is turned on.	When the power is turned on, the auto-degauss cycle is activated. While the auto-degauss cycle is activated, a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.
White does not look white.	Adjust the color temperature using the Color OSD.
