Question about Westinghouse Computers & Internet
Have 2 same monitors side by side. One began to flicker and color looks washed out. Tried all the adjustments but nothing works.
If the refresh rate is not properly set the monitor may have a wavy or an appearance that lines are going down ... This may also cause a flickering affect.
Distorted or skewed image on monitor. Issue: Distorted or skewed image on monitor.
Cause: This issue can occur from any of the below possibilities.
Windows Issue If your monitor has a proper display until it gets into Windows 3.x, Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, or Windows XP please see document CH000121 for software or setting related issues.
Loose or defective cable You may receive a distorted image when the cable is loose or defective. Disconnect the video cable going from the back of the computer and verify that no pins are bent, burnt or broken. Once verified re-connect the monitor cable.
Refresh rate issue If the refresh rate is not properly set the monitor may have a wavy or an appearance that lines are going down or across the monitor slowly or fast. This may also cause a flickering affect. Additional information about how to change the refresh rate can be found on document CH000558.
Interference A distorted image can be caused by magnetic or other types of interference. Verify no speakers, fans or other magnetic devices are close to the monitor.
Bad Monitor If the above possibilities have been checked it is likely that the monitor is bad. To verify this it is recommended that the monitor be temporarily disconnected and then connected to another computer. This can be a friends computer, a work computer, and/or a computer at a service center. You can also help verify a defective monitor by connecting another monitor to your computer. Note: Connecting your possibly defective monitor to another computer will in no way harm the other computer.

Actually this is a 'warning' signal from your lcd monitor. The problem is your lcd ccfl lamp are near to their life, need to change. The ccfl lamp like our home fluorescent lamp, when the lamp need to dead, the lamp will flickering first, after some time, will totally off(dead). So, this is a signal for you. Some lcd monitor, when their inverter board are using fairchild inverter ic(oz series), will easily shutdown your monitor when they detected some flickering on your screen (ccfl lamp). If you need more information on repair your lcd monitor please visit http://www.fastrepairguide.com . Thanks.

The flickering is most likely the florescent backlight having a hard time starting, Just like in a light fixture, as it gets old, it takes longer to warm up to get full functionality.
If under warranty, contact Dell for a replacement, if not, then when it becomes untenable, replace the monitor. Prices are dropping drastically, an new 20 or 22 In can be bought for about $150 or less
