Just moved my computer and related equipment to the new shop. It seems my moniter has developed a problem. Most of the time (but not all) the screen is shimmering, moving around. The pointer is still, but everything else is kind of quivering.
I haven't had thime to call a tech, I thought some of you might know what's up.
It is a 19" Gateway, about two years old.
Thanks

It's the power supply at the new shop, it apparently has a lot of noise in the line. Turn off the fluorescent lights and I bet you it clears right up. Light circuits on dimmer switches do the same thing.
Start unplugging things from the wall outlets.. water coolers.. refrigerators.. any kinda motor..

Ditto what Mike said, it sounds like dirty power to me. If nothing else you might try getting yourself a GOOD quality surge supressor that also cleans the power signals, theyre not cheap but they do make a difference.

Electric motors could definately be the culprit. Do you have a refrigerator nearby? We had one about 10 feet from my workstation at my old job. Every time the motor came on the monitor would flicker.

The "dirty power" is the most likely, but I had the same problem once. My computers have their own circuit, so nothing should interfere with them. After moving one across the room, I had the same flickering. We tried turning off all of the other breakers, and it was still there. I replaced the power cord to the monitor, and have not had a problem since. I tried that cord on another computer, and had the same problem. We decided the movement had somehow weakened the cord.
Not a guaranteed fix, but it's easy to try if you have another power cord around.

An Uninterruptable power supply might be the solution and is something I would suggest regardless of flicker.
There are two kinds, one runs your equipment from your service, when the power is interrrupted it switches to battery, this is problematic.
The other runs direct from the battery, the battery is continuously charged from service and there is no delay or fluxuation if the power changes.
The differentiation between the two can be arrived at by looking at the box. The first kind I mentioned usually notes that there is "only a blah, blah nanosecond switch time. You don't want any switch time.
Most of the newer models in the $150 - $300 range come with software, connect to your computer via serial bus and will actually save your open files and then shut the computer down if you are not there to do so.
This I think is very cool !
Models vary in many ways, most prominently advertised is the amount of time equipment will continue to run after the power source is gone. The price is directly affected by this. I don't see where great longevity is important as long as there is time for the computer to shut down.
Either way a 'UPS' as they are commonly reffered to should clean up a "dirty power source".
Also, many older buildings and I suspect newer ones as well are not wired with a true ground, this can be imperative for Surge protectors and UPS' to work correctly.
You would have to consult an electrician to verify adequate ground.
Hope this helps you !

Thanks everybody, I am on a battery back-up, surge protecter. Maybe not good enough to calm the interference? I suspect the flouresent lighting, will check tomarrow.
Cheryl, fill me in on the meet, have I missed something? This one I can make!
