I would appreciate hearing about the commonality and acceptability
of screen distortion on a high-end CRT display. I have now had 3
new monitors of the same brand (LaCie electron22blueIV) that distort
an image in similar ways. A perfectly round circle will balloon
outward when moved off the center of the screen (turns into an
ellipse). It gets progressively worse the further it is from screen
center. I have measured the difference in diameters and quantified
this as a 5.8% distortion at the extreme. Also, a skewing of square
or rectangular shapes is apparent in one corner of the screen. These
problems are still existent when I test the monitor in another room,
hook it up to another computer, and try another cable. Unhappily,
this third monitor has the additional problem of uneven color across
the screen. (The right side is preponderantly blue rather than
neutral.) These are all critical problems for my work as a
photographer and graphic artist and designer. The manufacturer has
already refused to simply take back the monitor and refund me my
money. It is too late to return it to the store I originally
purchased it from. I know that a good number of you out there on
this list have been using this monitor (LaCie electron22blueIV). Can
anyone suggest a mode of recourse? Thank you.
I know this might sound like a strange question but where, in the
world, are you?
It sounds like you are being affected by a magnetic field and if you
are moving the monitor around then you will be removing the
possibility of a close source so that leaves either a particularly
strong field in the Earth near you (are you on bedrock?) or perhaps
just the Earth's magnetic field overall. The original 21" Apple
display had circuitry that would detect fields and reset the display
automatically. All you had to do was turn the screen and it would
detect it and reset... I have yet to see that feature in any other
display...
I think that you are looking at a very good reason to upgrade to an
LCD display. They are not affected by magnetic fields in any way
(that I've heard)

I am using the monitor with a PowerMac G4 in New York City's East
Village, in a low-rise residential building. This neighborhood is
low-lying because the bedrock is much further down than in other areas
of Manhattan. There are no tall office buildings or high-tension power
lines in the immediate area. There is an electric power sub-station a
block and a half away. I can't imagine that the monitor distortion is
due to my location; Manhattan has lots of imaging professionals
working here. Could the problem be a streak of bad luck with the
LaCie's?
Thanks,
Lauren
Lauren,
My LaCie is the same as yours. It is the second "new" one that I've
owned (after returning the first as defective), and both of them had
the same uneven color across the screen that you describe. Have you
adjusted the purity controls? This will make the problem somewhat less,
but not completely solved.
My next display will be an LCD.
