Flutter or wave
Wednesday, December 7, 2005 by teddybearcholla | Discussion: Personal Computing
Sometimes my pc screen has this faint flutter or wave. It does not happen with any specific program. This just started about 3 weeks ago. Anyone have any ideas what this might be?
Thank you!! tbc

Any kind of electric motor can cause these effects. My desk fan at work does it to my monitor if it's within 2'...

Or possibly leaking electrolytic capacitors in the power supplies for the horizontal and/or vertical deflection circuits. Common in TV's as well.

It's starting to sound like we are lucky that they work so well so often! 
I once worked in lab where someone set up a magnetic stirrer a couple feet behind a monitor. We're talking distortion. I felt cars-sick for a few minutes.

I guess kind of like a garage opener that opens the neighbors garage door also!!!
I am happy to report, there was no flutter or wave today. I checked a few of the things that were suggested, connections, moved speakers, etc.
yes it does!!!

Barbara...you don't actually have to own the Cell...it could be someone outside nearby...
Other potential causes....
Fretting of various connectors...graphic card, monitor plugs, etc....heat does that....try resetting each connection.
Voltage power supply issues....similar reason...or failing PSU.
Monitor just getting old....they do have a finite life...which varies and is never really reliable. Some might last 20 years, others 2.
My Loewe TV lasted 8 ....[tube died]....$2600 AUD.
It happens...
