There is too a source of magnetism: you've got a planet with a fairly decent sized magnetic field sitting underneath it. This ain't a joke. You'll get different distortions depending on where the monitor is sitting and what direction it's pointing. Try rotating the monitor 180 degrees. That's good enough to make a visible difference in most locations. The people who adjusted it may have done a perfect job, but unless they did it in your office/betroom/whatever, it doesn't matter much. >Anyone know Anything more about this ? How can I adjust the monitor myself ? Sure, you can adjust the monitor yourself. But it involves moving around several little magnets which are mounted on the yoke (it least it does on most CRTs, I haven't seen the inside of a MegaPixel yet). This is kind of a black art: each magnet affects all the others, so moving one affects the one you moved you before, so it gets moved again, etc. Monitors also have extremely high voltages inside them, which need to be discharged before you start mucking around. This is all real easy if you know how, and not too bad if you've seen someone else do it and know something about why it all gets done. But if you don't now how to do all this, then have someone else do it for you. It has a much better chance of working that way, and both you and the monitor will be much safer. I could explain how to do it here, but them someone will manage to zap themselves anyhow, and I'll be on the receiving end of a lawsuit. So I'll just shut up now.

I have blasted myself enough times that I can tell you it is NOT a good thing to play inside the monitor unless you have the proper equipment. Look it is not a matter of warrantees, but a matter of LIFE and DEATH. If you bought your monitor within the last year it should still be under warrantee. So if the monitor is maladjusted go to your local service center and ask them to adjust it for you. If they wont do it, call NeXT and grumble about the bucks you are about to pay for a professional to do it, and the get a professional to do it (no, not your brother in law who went to some high school tech class, a real pro... yeah hard to find).

Presumably, you could remember the orientation wherever you're planning to put the monitor, and make sure it's in the same orientation at the "shop". After all, you're presumably taking it into someplace within an hour or two of your place of work or home - hopefully the earth's magnetic field isn't going to change _that_ much. Of course, various fields in the "shop" (which might be a computer lab or something) are also going to skew what you get when you take it home. Later,

Simply making the monitor face the same direction has not resulted in identical behavior from my monitor, but that's a good idea. But you'll probably have a hard time finding a technician who's willing to put up with your idiosyncrasies. He'll just tell you he kept it facing North, when it actually faced South the whole time. Maybe there's a geologist (or some such) in the crowd, who can tell me why just moving 20 miles or so can make such a difference in the monitor's behavior. Assuming, of course, that it really is the earth's magnetic field.

Look it is not a matter of warrantees, but > a matter of LIFE and DEATH. You'd have to work very hard or do something very stupid to zap yourself with this monitor. The external black plastic cover just covers an inner metal cover (shielding?). In the back of the metal cover, there are labeled holes for adjustments. To make adjustments, you use a PLASTIC television adjustment tool, available at any Radio Shack. Just don't stick anything conductive into those holes, and you'll be safe enough. Needless to say, I do agree that if your monitor is still under warranty, you should make a "professional" do it. Not because the "professional" can do it better than you (though that may well be the case), but because that's what you paid for. Also, there are many variables to adjust, and their interaction is not very clear. If, however, you do something stupid, like stick a metal screwdriver into the adjustment holes or pour Dr. Pepper into the monitor, don't do it unless under supervision of a physician. Jacob

Assuming, of course, that it really is the earth's magnetic field. Well, I'm not a geologist, but would a geophysicist do? I'd bet it might have something to do with throwing the monitor in the back of the pickup for the 20 mile move. You might want to put it back in the box in the future. (;-)
