I have installed 1020hp laserjet printer today. Then I found that the screen of the monitor is shaking. I have two operating systems - 1) Windows 98 and 2) Windows XP. The System unit, monitor, speaker, printer, UPS all are on the same table. Is it cause any problem later?

I have a similar problem like this. Right now my monitor makes fast, wavy animations on the sides which I think is much like yours, except faster, right?

Well the technician old me that because display is exceptionally well it means that it cannot indicate a bad or old monitor. He said that something is magnetizing the inside of your (monitor which makes the display) and that could be anything big or small. Try separating the computer monitor from the other components, whether big or small.

Hope this could help :)

I have the same problem. My home computer backs up the wall where the dryer is. If the dryer is running the screen pulses like you described.
