Flutter or wave

from WinCustomize Forums
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

Sounds dangerous, but what does it mean?

Probably RF interference....CRTs are prone to distortion through fluctuations in nearby magnetic fields...mobile phones [cells] could be one source....

Whew!!! Thank you Jafo!!! I was really hoping it is nothing serious!!!

Or it could be microwave emissions caused by a phase inversion in the tachyon pulse generator, vibrating at the sub-harmonic level, in which case the monitor will either fry your brain or explode...

Speakers too close to the monitor can slowly cause problems and discoloration over time.

Fuzzy, what does that mean in English? I'm already in another galaxy!! I mean the exploding monitor part!!! Can that really happen?

NT...speakers are right next to the monitor, and have been playing music alot lately, usually I prefer quiet...so how far away would you suggest I move the speakers, just in case the monitor explodes!!!

Hmmmm...echo...

Speakers near monitors MUST be shielded...specific computer speakers usually are....if you are using non-shielded ones their magnets will colour-distort the screen....and you'll need to degauss....[generally an option in the monitor settings - buttons on front].

If they are unshielded you'll tell...if you move a speaker around in front of the screen [while its on]...and you see a dark shadow on the screen.

If so....move the speakers  a foot or so away from the screen...or more....if they are huge ones...[HiFi speakers]....

Oh my, sorry about all the posts...I kept getting that yellow highlighted page about a server...it never seemed to go through...obviously it did

Just tried what you said... no shadow...so they must be ok then!!! Thank you!!

Have you tried changing the refresh rate? R-Click Desktop->Properties->Settings->Advanced->Monitor (at least on my system) will bring up a panel where you can change the refresh. This is only a suggestion, if I really had to guess, I'd say your monitor was just wearing out.

I had a friend once asking about this and I thought that the monitor was going too, until I learned that she had taken to leaving her cell phone on the end of the desktop about 3 feet from the monitor. Everytime the phone either rang or would search for an antennae signal her screen would fluctuate madly. Try having someone call your cell phone and see if you get the same flickering and then move away from the computer station until it stops and then remember to keep your phone at least that far away (I don't get the screen flicker with mine, but I do get speaker interfernce noise when the phone rings or searches for a signal.).

Thank you...can't be cell phone, we do not own one, I don't seem to have the change refresh. It could very well be the monitor is going. I think my computer is about 4 or 5 years old. I suppose there is no general time period as to how long a monitor will last. hp pavilion mx 70, that is what I have, and windows xp home. I will keep an eye on it!!

Hey, that is a great suggestion, DigitalDanes! I've had a similar experience. On a road trip the passenger had her phone set to silent in her purse, down near the car stereo. For hours we experienced intermittent, loud, static - I figured my MP3 player or the casette adapter was going bad, kept trying to adjust the cord looking for a loose connection. Finally she noticed it vibrating ( a magnet spinning a metal weight around ), and as she answered the static stopped.

Nice deduction, even if it isn't the final cause.

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...

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

electric staplers also

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.
