Why do monitors shake?

[iLoveDivX]

The physical case of the monitor isn't shaking, but the screen itself is. It's similar to when you press the degauss button except for this is little, subtle vibration. Anyone ever have this happen before? Know what's causing it?

Did you just turn on a tv next to it or somethign?

maybe u been sitting in front of the monitor too long. take a little break. at least thats what happens to me sometimes.

If the monitor is a few years old I would say one of the filter caps on a power supply is weaking letting some ripple through.

Try turning the brightness down a little and see if it still does it. That's not a perfect test but if the shaking goes away it points to a weaking power supply in the monitor.

It is cause by outside interference. Try adding another iron core attachment to the monitors cable. That sometimes will help.

Also try moving your monitor to another place in your room.


Things that cause intereference. Flouresant lights, fans (especially small ones), other electronic equipment, power line noise.

Electromagnetic interference caused by other electrical devices plugged in the same outlet/power line.

In my case, the microwave in the kitchen is run on the same lines as one of my computers.
Whenever it is being used, the image vibrates.
When it is not, the image is still.

don't go on your computer after using physcotrophic drugs

Make sure that nothing is right beside or close to the monitor. I had the same problem last year in my dorm with one of my fans sitting about a foot from the monitor. If something isn't actually wrong with your monitors, that's more than likely the problem.

Could be noise in the power lines. Try different frequencies. My monitor shakes no matter what unless it is at 60Hz.

maybe you're just noticing the flicker from a low refresh rate. See if you can get it up to 85hz. Also check that there isn't any motors (read: fans) plugged into the same circuit or sitting nearby. I had that problem last year, and it was a fan that was plugged into the same power strip.

very interesting...

My cell phone, if close enough, will make the screen flicker.

Oh that was your computer I was doing that too? Sorry.

i always wondered this too, b ut never bothered to ask why, interesting, i'll move my fan tonight and see if it makes a difference, is there any long term damage possible from th is?

Well it can't be good for it, but I wouldn't worry about it killing your monitor with just a little abuse. I'm pretty sure you could even let it go for a year or more like that without any side effects. I'm not sure though.

F = ma

Dang, I of course overlooked the obvious answer here.

You should see what a welder 20 feet away will do to a row of 11 21" monitors. It will make you dizzy.

Ameesh What are you trying to say with F=ma?


bonk102 Electrons are emitted at the back of the tube. Magnetic fields are used to align the electrons with the proper place on the front of the screen. The point of that very short and incomplete explanation is that monitors are susceptable to interface by outside magnetic fields. AC fans emit a magnetic field. If not too close it shouldn't do any long term damage to the monitor. It won't do you any good looking at a shakey screen though. It gives me a headache.

Yakko Another worthless post to up you post count I see.
