How's this? Fuck you.

Ah, certainly a reasoned, rational response in keeping
with the traditions of your participation here. Thank you
for continuing to live down to everyone's expectations.

Oh boy! 1998! Wow.

Yes - it was in 1998 that the VESA organization was ASKED to
publish such a paper, by a consortium of Western U.S. power
companies and related organizations.

Do you happen to be familiar with the effect the planet's field has
on upright game video screens when placed in a near horizontal fashion
in the game cabinet? Depending on the position of the game, the
convergence and colors all get screwed up by the Earth. Imagine
that... Standing fields pass through the planet with nothing to stop
them... just like I stated.

Right. Magnetic fields, not EM or electric fields. You still
fail to grasp the distinction between these. This effect, by
the way, has absolutely nothing to do with whether or not the
field in question is "standing" (non-time-varying), but simply
that it is purely magnetic in nature. The Earth just simply doesn't
happen to generate a field which is (significantly) time-varying
(on this scale of time). If it did, the same effects would still
occur.

I suspect you're going to tell us, but I also suspect you're still
incorrect as to the root cause of the problem you're seeing.

The tube has no such features as those you described.

You don't believe that tubes have been made with
internal magnetic shielding? That alone speaks volumes
regarding your familiarity with this industry.

Shall I point you to specific types?

You're an idiot if you think that sets you apart, and a bigger one
if you think that that is a requisite to know what is going on.

I've done everything from 50 different upright and cocktail video
game displays to eyepiece sized viewers to high brightness jet fighter
ruggedized versions, to FPDs, and there is that big bubble faced job
for 70,000 ft I mentioned.

Are you qualified to use the word "qualify"? I mean you do seem to
think that you are some god compared to others, when you couldn't be
farther from the truth.

I've seen people like you in the industry many times. You're a
legend in your own mind. Sad that there are so many in the industry
that suffer from your disease.

This seems to deserve only a three-word response, to wit:

Pot. Kettle. Black.

"A bucking magnet helps cut down on the stray magnetic field"

What part of "helps cut down" do you not understand?

That matches my declaration that it doesn't quite do the job, and
full shielding is what is needed, directly around the magnet area, and
inside the cabinet shell.

What you won't find in these catalogs (at least, I never have) is
anyone selling mu-metal or boilerplate for shielding. Think about
all the cheap little desktop speakers that don't weigh much.

They have cost of mfgr to consider. Think.

Reality still says that said shielding is weak, at best.

(I can hardly imagine a copy writer trying to explain the
advantages of "bucking magnets" to Joe Sixpack.)

That is the same reason, Joe SixQuack's PC speaker selection guide
has no Mu metal sheet offerings. Doh!

You'd think the monster cable twits would have some lame, high
priced fudge out there though.

Hey, maybe this is something we can sell to the "golden ears"
set! They love things that are totally ridiculous, so 800 pound
speakers might be a hot item!

You would have a hard time making the speakers next to my PC weigh
800 pounds, even if you used the heaviest metal we have here.

You would have to get some of that star compressed stuff.

I am certainly understanding the source of your reputation
in these discussions at this point.

You're an idiot.

Please explain how simply being about "monitors" somehow
magically takes this discussion from one concerning purely
magnetic fields to one concerning EMI.

I didn't say a goddamned thing about magic, dipshit.

You DO understand
the distinction between the two, don't you?

I can distinguish between an asshole, and someone that knows how to
iterate facts.

He is trying to abate influences for one monitor to the next, not
some huge field as you seem to suggest.

I never said that, retard boy. I said that about the tube which I
referred to. Your blanket baby bullshit claim that I believe that
about all CRT tubes is just as retarded as any other unknown assertion
you make, and you fucking do it all the time.

Fuck you... Again.

That alone speaks volumes
regarding your familiarity with this industry.

No. It speaks volumes about your stupidity in presuming you know
something about someone, when you have no clue whatsoever!

Shall I point you to specific types?

I buy tubes from Richardson, Sony, and others.

Again, dipshit... I do NOT need a primer from your lame ass.

How many invitations to shut the fuck up does it take with you?

Frankly, I don't care what you think you have to
"measure up to" - and you've already more the adequately
demonstrated your level of both technical qualification in
this area and your professionalism. In short, you're irrelevant.

I can only base my assessments of what you know from
what you've demonstrated here. So far, color me
unimpressed - and the assumed level of understanding on
your part is falling fast. If you want to change that, I would
suggest that the best means is to actually demonstrate some
competence in this subject, rather then just spewing obscenities.

I guess if you can't do anything else, though...

And it continues to be painfully clear to which of these

Correct. Now, please leave responding to that question to

The expected response, since you can't discuss any
of the factual points raised in any meaningful manner.

Again, dipshit... I do NOT need a primer from your lame ass.

Probably true, since I've never taught at the high-school
level or below.

How many invitations to shut the fuck up does it take with you?

As many as you like; they have at least some entertainment value,
even though the technical content is zero.

I hope it would be fine to ask this question here. Seeing you people
discuss this topic so furiously..., I remembered that my monitor shows
some sort of color fadings or such things when it faces East. In all
other directions, I have checked this myself. This is an LG
Studioworks 15" color monitor purchased in Feb 2002.

The colors fade towards green but only on the top right corner of the
screen. I have observed that this effect disappears even for about
15-20 degrees change in orientation towards the North, but requires
much more change of orientation towards the South (45-50 degrees
perhaps) I used to wonder what causes all of this, but now from your
discussion, it appears to be because of the earth's magnetic field. Am
I correct?

Oh! and well, nothing significantly apparent happenned when I used the
degauss and change of refresh rates etc. that my monitor supports. In
fact I don't want to change the refresh rates at all since then Linux
causes some sort of a funny trouble then. Please do inform me.

Any object that can retain a magnetic field (such as ferrous metals or
the shadow mask of a CRT) can become slowly magnetized by the Earth's field.
When a television or video monitor is left in one position for an extended
period of time (from months to years), it becomes magnetized in a manner
that is parallel to the natural field lines passing through or around it.
When you rotate or move the monitor, now its field and the Earth's field
are no longer aligned and the colors will shift. Degaussing the monitor
usually cures the problem. If not, get a larger degaussing coil and do it
manually.

Cheers!
