display narrowing

E

emma_middlebrook

Hi

Not too sure how to explain the problem in a technical way but my 17"
monitor has begun narrowing it's display.

Especially when it's 'cold', the initial display can range from about
one inch wide to eight inches wide. If I just tapped the monitor on the
top it used to widen straight away to full width. Now, really banging
it has little effect but it still responds eventually - I'm afraid it's
on the way out completely.

It also occasionally shows a vertical, glowing line right in the
centre.

It's an Iiyama Vision Master Pro 17, my indulgence when I bought it,
around 1997. I don't fancy an LCD monitor because they always seem a
little 'blurred' to me. Bit of a luddite comment I know!

Can it be fixed in an easy way?

Don't expect much from 10 year old displays, cut whatever losses you
feel you have and by a $100 17" display.

Hell, if you're a CRT fan, you should buy a 19" or 21" example while
you still can. I'm dreading the day my CRT fails and I have no choice
but to buy a "works well at only one resolution" LCD piece of crap.

Yep, I just bought a refurbished 21" IBM P275 CRT because I don't like the
limitations of LCD. I've had two LCD's and for my purposes CRT is much
better. Don't know what I'll do when it's impossible to get a CRT anymore
either.

Heh. After reading your message, I went to Ebay and bought a NEC
FE2111SB. This is a rebadged Mitsubishi DiamondPro 2070SB 21"
monitor, and uses a DiamondTron (aperature grill) .24mm stripe-pitch
tube.

I bought it my young daughter, who has always run a Nokia 447X 17"
(Sony .25mm stripe-pitch tube) on her PC. I'd been thinking of
upgrading her to a 19" LCD, but then I thought "hell, for a couple
hundred bucks, I can get her nice used 21-inch CRT". I thought about
buying a brand new one, but I could not find any new AG monitors,
which I greatly prefer over shadow-mask.

I'd like to find a pristine Sony F520, but I'm afraid that anyone with
one of those beauties as holding tightly onto it. 8)

There aren't any, unless someone has some old stock sitting in the
warehouse. All AG CRTs for monitors went out of production
quite some time ago.

Those are nice tubes. I used to have one before I took the LCD plunge,
except it was the 22" model. The IBM P275 I just got is a Sony
Trinitron aperature grill tube, very nice.

Yeah, I mis-spoke. They do call it a 22", although the viewable
diagonal of ~20" is no larger than what 21" montitors usually have...

No doubt too expensive to make, in this new world order, where CRT's
are perceived to exist only to serve the cheapest segments of the
market.

Nope - lack of the necessary level of demand to keep a
CRT plant in operation. The AG tubes were never going to be
a "cheapest segment" sort of thing, and the loss of practically
all mainstream monitor volumes to the LCD leaves an insufficient
market, in terms of revenue, for continued economical AG
production. (In other words, you're partially right - the per-unit
costs of making a CRT aren't necessarily any higher now than
they were before, but you DO have to be able to expect a certain
minimum volume of sales in order to justify keeping the factory
open. You might not like the analogy, but - a buggy whip is
still, fundamentally, a cheap thing to make, but that doesn't mean
there are a lot of buggy-whip factories around.) For now, of course,
CRTs continue to be made for TV consumption, but that's a whole
different beast than a monitor tube.

Again we appear to miscommunicate, Bob. You seem to be say nothing
that clearly disagrees with my statement, yet you start out with
"Nope".

The issue at hand is "AG CRT monitors".

The point it, Bob, the AG plants all went away, while shadaw mask is
still in productiuon.

The point is, AG is more expensive than SM, and that's why it's not
viable any longer. "High end CRT" is today something of an oxymoron
to the buying public.

You missed my point entirely. See above.

About 1/2" dif. My 21" is actually 19.8" viewable.

Yes, Bob, whatever I say. I would hope that you would have worked on
your reading comprehension and stopped trying to be contrary at every
opportunity.

The seller hasn't contacted me yet, though. Hmm...

That's Ebay for you. I don't buy from Ebay. Luckily, there is a computer
store near me that sells refurbished CRT's. They get in different models
all the time. You can get refurbished CRT's from Tiger Direct too but the
shipping charge is hefty.

I got the monitor. It's working well, although not quite as sharp as
I'd hoped. I looked-into it a bit more and realized that, although
they use the same tube, NEC cheapened it up (lower-bandwidth
electronics), compared to the Mitsu Diamond Pro 2070SB. Grrr.

I never did like NEC monitors. 8/ Oh well, it's still plenty good
for it's normal usage of 1280x960 @ 85Hz. Indeed, it can do 1600x1200
@ 85Hz.

If I get another big CRT, I think I'll only consider the top-line
Mitsu Diamond Pro or Sony F520. My work monitor is the 19" Mitsu
Diamond Pro 930SB, and it's tack-sharp.
