Waving Screen

Few months ago bought new monitor. Screen was wavy at times...when central air was on or washer dryer running...sometimes nothing running. Did everything bought universal power supply etc. Downloaded new drivers and changed refresh rate...not sure which did it but finally no bouncing picture. Last week bought new computer using same monitor and bouncing back. Am now using XP would imagine all new drivers on here. If central air kicks in or the washer dryer running my screen makes me quesy. All on seperate circuit brakers and on a different floor of house not even close to computer. HELP

 

A jittery (or wavy) monitor display is most often caused by speakers too close to the monitor. You said it does it when "sometimes nothing running "...perhaps a sound file is playing? Try moving the speakers 6" or more away from the monitor during a "jittery phase" and see if that solves the problem.

Other things too close to a monitor which can cause the jitters:
1. Another monitor
2. Electric fan
3. Fluorescent light (this does it to my monitor)
4. Metal shelf
5. laser printer
6. subwoofer
7. non-shielded speakers

 

8. beer
9. wobbly rubber chair

 

Miz...ty but it isnt any of that....It has to have something to do with the electric current or the magnetic field...just not sure how to correct it . Have a filter and a universal power supply on it...could it be as simple as refesh rate?

 

Yes, if the refresh rate is too slow the screen will look like it's "vibrating."

The default refresh rate in XP, for example, is a sluggish 60 hertz....or maybe it's 65...something like that.

Go into the display settings and jack up the refresh rate to at least 75. If you can still see the jitters, jack it up some more. Keep doing that until it looks right to you. Ignore the warning about "doing this may irreparably damage your monitor, render it useless, void the warranty and cause great hardship throughout the land "...or whatever it says. I have it on good authority (the TechTV Geeks and Lab Rats) even extremely high refresh rates won't damage your monitor.
