These models incorporate the award-winning DIAMONDTRON NF (Natural Flat)
aperture grille CRT. They are ideally suited for advanced applications such
as CAD/CAM/CAE, imaging and professional desktop publishing.

Above  is the spec and based onwhich I bought.

If there is a 'pin cushion' setting button try that - can be used to make
screen square. I have the same monitor with no problems so you could have a
faulty one - try getting a replacemtn one asI believe they have a 5 yr
warranty (or used to)

Duncan,

You will not notice this after a few weeks.. you are simply used to looking
at screens which bulge outwards, and which are not using perfect flat screen
technology... your brain/eyes try to compensate by making your screen look
like it bulges inwards.. give it a few weeks...

Open a window full screen so it's edges are as close to the edge of
the screen as possible. Now put a ruler up to the screen. Are the
edges ACTAULLY straight?

I notice the same thing with my new flatscreen... Takes a while to get
used to after using a "bulging" monitor for so long.

No - a flat screen just takes a bit of getting used to after
years of looking at convex screens. I adjusted to mine after
three or four days ... after which conventional screens started
to appear painfully convex.

I must say i never noticed when i changed from a normal monitor to an LCD
one which is flat, you can adjust all the geometry (in this case pincushion
?) though.

Forgot to mention it came on Thursday and I was on the phone to supplier,
then manufacturer direct and the latter agreed to swap as the effect was so
bad (with straight edge and more than the two mill he said was within
tolerance) that they collected and replaced yesterday.

So this morning set up new monitor and whilst the distortion, to my eyes,was
not as bad I am struggling. Could this be something to do with wearing
glasses.

I have just come back from Staples after scrutinising CRT and TFT and am
still not sure whether I feel I will get used to it. I take some of your
guys comments that after years of looking at Convex CRTS my eyes may need a
period of readjustment. However I have worked on quite few differing
computers and never found this problem before.

Bugger -- shall I persevere.

You could always grind a bit off the centre of your specs - or it 
maybe the outside, Graham will correct me if wrong - to compensate.

Last time I checked there were only two manufacturers producing
this particular flat-screen CRT technology - Sony (Trinitron) and
Mitsubishi (Diamondtron - the same tubes, but with different
electronics, were also used by Taxan and IIyama).

I must admit I have thought about ringing my optician to see if he suggested
special specs.

Nor would you unless you've been given a flat screen to use
before (unlikely as yet in a commercial environment). 

>Bugger -- shall I persevere.

I would: despite experiencing the effect you described on day
one, I'd find really hard now to go back to a conventional CRT. 

Mind you, I was aware of the fact that they're different and that
some people seem unable to get used to (a) the effect you
describe and/or (b) the two faint grey horizontal lines that
flat-screen CRTs always exhibit - one a third of the way up the
picture, one two thirds; these, though faint, are noticeable
against a white background, e.g. when text processing. So I drove
a good distance to my intended supplier's showroom to view one in
operation before placing my order.

Just been trying to see if I could fool it by pincushion, etc adjustment but
no such luck.

All the monitors in our sales office are LCD's, we have to make do with

Is that on all FST's, i thought that was just the Sony trinitron tube ?

No empty jam jar but if I have a jam sandwich I might.

Cannot answer regarding other makes but the Sony original is superb
and I cannot recall any problems switching between my other older monitors
apart from the 10" green screen.

I thought this was tension wires in aperture grille tubes? Flat or 
curved? They're certainly here on this old-ish Trinitron with a 
convex screen.

Well i thought they were in all Sony trinitron tubes and no others but there

Stupid questions first ;)

1) Are you the only person who notices this?

Different people may see the same thing differently.


2) Do you wear fairly strong glasses?

I've found that strong glasses often distort straight edges when viewed
from an angle, try removing the glasses and compare.
Also, close one eye and view the edge of the picture from directly infront
of the edge, is it still bent?


3) Is this the first FST monitor you've had?

After using a 'round' monitor for several years it can be a bit strange
viewing a truly flat monitor for the first few weeks, your eyes are used
to 'correcting' the bent sides of a 'round' monitor, so they make a flat
screen look distorted.

Three other people looked one who uses computer now and again for very short
time. The latter said looked OK to her but the other two who use computers
daily said they said it gave a concave appearance.

My glasses are for reading only and not very strong, tried with two old
pairs and without and still found the concave effect. If you look close at
each of the vertical and horizontal lines and it appears straighter.

Yes my first FST but I am worried as I spend around five hours daily at the
computer working on many files that include design layouts with multi
photographs and text boxes. Since my first posting yesterday morning I find
myself getting a little more used to it but no lessening of the concave
effect and feeling extremely disappointed with what should of been a quality
monitor. Number one in PC Advisor month after month.

When I first bought my flat-screen TV it took me a while to get used to it,
it too looked concave for a few weeks. Now it's flat. I guess us older type
are just so used to looking at convex screens that we have a hard-wired
compensation system in our brains that needs a little time to adjust.

After reading other posts yesterday I thought I would just settle down and
get used to it. But after going round a few computer shops and speaking to
my engineer I am told that sometimes, even after a few weeks, some just do
not seem to get used to this type of monitor.

So as I type it is re-packaged and I have submitted a returns request
(internet purchase) even though there is a 15% charge. It is just stressing
me out now.

Not on all... the sony trinitron, yes, but flatrons (i.e. LG flatron) they
have done away with the tension wires...

Let me just add my two cents.  Earlier you posted about a 2 mm curve to
the monitor edge.  I measured my CRT and I have about 2 mm of
pincusion.  I think that is a very minimal amount of deviation for the
eye to see.  But if it bothers you, then I guess you should send it
back.  Unless you got a good price and can sell it on Ebay.

It's a different design altogether.

I've never had a problem with pincushion on any digital monitor, there is
normal a very wide range of adjustment, you should be able to get it to bow
in or out regardless of the shape of the screen surface.

Bill Hooks, are you saying that all monitor users without this wired up monitor (Sony)
original design can have a collapsed screen if they do not agree with the display.

When you say "mill", you are talking about milimeters, right?  Mill is
normally used for a thousandth of an inch "mil" and milimeter is "mm".

Sorry yes millimetres

Couldn't agree more that if there was the range of adjustments you could get
eradicate. However on the three monitors in my house (one due to go
back!!!!) there is no adjustment for my problem which is top and bottom
bowing in.. Why do they have left/right pin cushion adjustment but not
top/bottom.

Because pin-cushion involves adjusting the waveform in the
horizontal yoke to the vertical position.  No single waveform will
alter top/bottom pin cushioning.

Wow -- a week ago a monitor was a monitor but now I am reading all about the
differing types and realise there's more to it than meets the eye.
Excuse the pun.

Perhaps a glass of wine before I use the computer will be a way of getting
the final adjustment needed.
