Monitor Distortion

[jjsole]

I've got three monitors on my desk sitting in a row. When I turn one on, the other(s) right next to it get this wierd wave of distortion for about a second. What is this, and is it 'unhealthy' for them?

Sounds good, entragian, thanks. I've usually bought cheap monitors and wonder if thats a symptom. I'm curious to what causes it, but if its not hurting it, thats key.

LOL, I came into this thread wondering, does he have multiple ones on his desktop?

I told ya all I am fysic!!!!!!(psycic)

I am using a new Panasonic S70 monitor on the right, and I just put a 14" OLD Datatrain monitor beside it, the new one gets all these lines and stuff, and I am scared, so I moved them apart as far as I can, and I can BARELY notice it anymore http://sysopt.earthweb.com/forum/smile.gif

Congratulations, Carnac (MTP)! Here's my credit card because I could use a fysic http://sysopt.earthweb.com/forum/smile.gif to answer some other questions...

Your's sounds more extreme than mine, but is similar that its with an older monitor (well, mine aren't really old, but very cheap). I don't have space to move them apart, so I'll have to keep going unless I hear its bad for some reason.

It won't hurt them.

i would be careful about that, it sounds like the older monitor may have a big magnit inside and you know what happens to monitors when you put a magnetic field close to it.
yep it will stuff it.

Monitors use large electromagnets to focus the electron beam onto the phosporus screen. What you are seeing is some magnetic leakage from the older screen. As long as it is transient then I wouldn't worry about it but I would be tempted to move the screens apart a little though.

Run to a metal shop and grab a Huge Hunk of lead, and place it between your monitors. Just watch out because your desk will bow and eventually snap from the weight of the lead.
On the lighter side, eventually you can melt the lead down and make sinkers for all the fisherman in your area.

kidding of course. But on a lighter note, if the monitors HAVE to be that close to each other, you can always take some tinfoil and wrap one side of the monitor, or make a wall. Its ugly as can be, but it will block the field being sent out.

jjsole,

The weird transient that you see on a powered monitor when you turn on a monitor that's located beside it is caused by the degaussing coil inside the monitor being turned on (you should hear a brief humming sound accompanying the distortion too!). All monitors ahve degaussing coils to reset any residual DC magnetic flux in the shadow mask or aperture grille (usually made of Invar or some other magnetic material).

It's normal behavior and nothing to worry about!

I'm going to try putting up a little wall, and see how the tinfoil idea works. I really don't want to encourage fisherman around here, so the wall is the better of the two suggestions for me. The waters are just to dirty and I might windup buying the fish at the grocery store, and want to avoid that.

Thanks for the replies. It's good to know more about what's going on.

ps thanks Tony. missed you post in 'posting transit'. Your expl. is over my head, and I like that - thanks.
