At a loss, shaky monitor what can I do?

[halve]

Ok here it goes, I posted a few times about a monitor in my bedroom that has been giving me nothing but trouble. I have narrowed it down to somthing in my room, any monitor I put in my room and the image shakes, sometimes it shakes on and off like a beating heart. I have tried differernt machines all together, different outlets in the room, UPS backups etc etc etc.

Here is what I have noticed, when I hook a extension cord up to a outlet outside the room say 50 ft away and when I carry the monitor into my room it begins to shake. So I think it must be some sorta device in that area causing the distortion in my monitor. With this in mind I have unplugged everything and anything in the general area, to no luck. Sometimes the shaking is barely noticeable, somtimes it is unusable. I have also noticed when air condtioning or some other big device kicks on, it can increase the shaking.

I am down to very few ideas, perhaps wrapping tin foil around the monitor to "shield" it? Or if all else fails, calling a electrician and bringing him in.

Have yall ever heard of anything like this, and can you think of any other ideas? The monitor is a Dell P991.

Thanks very much

At work, there is one computer that is next to the power room, the screen would vibrate enough to make you ill, but if you moved the monitor about two feet away from the wall it would be fine, the other fix was to set the refresh rate to 60hurts(as in "your eyes") I guess that at that refresh rate the monitor was in sync with the emf (electromagnetic field) generated by the power lines.

Try it at different refresh rates and see if you can find one you can live with or change rooms?

I had this same problem in my new apartment. I could never get it resolved.........

I ended up buying a LCD monitor and it is all good now.

I had the same problem.. Then I bought a APC Power Backup/Surge Protector and it fixed everything.. This was after I RMA'd 2 monitors and replaced the video card a couple times.. And the power supply.

Could it be that your airconditioning unit is on top or near the top of your room in the attic? Or maybe the unit is outside your window.

Have someone else look at it ............. at the same time you do .......... so your sure it's not your eye/s!

Seriously ............. it happened to me.

It's called EMI (Electro Magnetic Interference). There is a magnetic field being generated somewhere near by and it is messing with the electrons as they fly at the screen from the gun. When I was living with my parents at home (we had a decent sized house w/ a huge chandaler (sp?) and whenever the chandaler was on any monitors in the house would start to look wavey. You probably have a strong power source near by. Try turning lights off or unplugging electrical things around it. Is there a circuit breaker or transformer near by? Also try putting it in another part of the house or encasing it in lead j/k

If I brought in a electrician could he somehow determine what device in my house is causing this EMI field? My last resort for this would be to maybe try a LCD monitor, but would this EMI field effect a LCD monitor also?

Thanks much

I do not know if an electrician could pinpoint the source of the EMI. If I were you I would try turning certain things on/off in the room and looking for things that use up a lot of electricity.

As someone said earlier they had this problem, bought a LCD and everything was fine. In a LCD monitor there is not a stream of electrons being shot at the screen. Instead there are liquid crystals that are bings turned on and off. I do not thing that you should experience the same effect w/ a LCD. Although, it is an expensive solution :/ Buy it from somewhere where it would be easy to return it the next day if it doesn't work out for you. (ie. Best Buy)

Hope this helps.

Yes an LCD will fix the problem because as already stated the pixels are physically attached so there is nothing to move. THe only thing that happens is that the pixels turn on and off.

My problem could not be solved because I have a one bedroom apartment and everyroom in the apartment was affected........that is why I went with an LCD. Since I do a lot of programming, I am very happy with the text quality on my LCD.

an electrician could probably determine the source of the EMF with one of those handheld EMF detectors (even I have one)...just call one and ask!
