Greetings kony,
Thanks for the comments. I'm not considering discarding the
viewsonic. But, it's time is perhaps near the end.
I haven't researched this, but since you brought it up ... <s&g>
.... how do I evaluate lcds when comparing them to a crt? I run
the viewsonic (16in viewable) at 1152 x 864, 75 Hz refresh rate.
It has a .27mm dot pitch. This gives me adequate room for
overlapping windows, a good print size for me, and adequate
detail to do some graphics/photographic work. I plugged in a
15in lcd and found it's maximum/optimum resolution of 1024 x 768
to be thoroughly unacceptable on all counts, even after fiddling
with the various win xp desktop/scheme parameters.
I do have to research this as the viewsonic screen had a
distinctive green cast to it now.

You dont' necessarily, instead buying what seems to fit your
present and future needs regardless of past use - because
applications and needs change over time.

As for text, LCDs generally allow use of a little smaller
pixel pitch or further distance than a CRT would. I'd think
a 19" or 22" would be a starting point but only you can
decide of a widescreen monitor is what you want... they're
certainly more common today but there are still fair choices
in 19" 5:4 ratio in the market.
Graphics work may make a VA or IPS screen more suitable
because of better contrast and viewing angle. They cost a
bit more and are rarer in 22" size, you might go to some
stores and also look at the tradeoffs made with a 20.n"
screen as they're more often *VA or IPS instead of TN
panels. Budget has a lot to do with choices, after getting
an idea of the physical size and dot pitch you find
acceptible then online reviews can help in finding better
color and contrast among those size(s).
Something else worth considering is that you will probably
get used to whatever monitor you choose so long as it
doesn't have some particularly bad problem, will be able to
adapt and use it fine even if it doesn't look the same
side-by-side with what you were used to.

Greetings,
Good points all. I will do some snooping, getting a better
understanding of the lcd vernacular. <g>
Had a power outage here. And I was outside working. So the
beast sat idle for nearly six hours. When I powered up the
system, the monitor power light was on but there was a black
screen. Turning the monitor power on and off brought it back
to life ... but with a distinctive green cast ... . After
being on for about 40 minutes the greenish-ness has faded
leaving the brownish gray. So I'd guess there's more the dust
on the tube! LOL! <g>
Thanks for the conversation. I'm probably 'off the air' for
awhile now for the rest of the day. Then, I'll go out and
look at all these 'new fangled' contraptions. <g>

AOC is also sold as Envision, and my Envision EN-710 and EN-775 both
work fine after several years
If you need a new CRT monitor, try dumpsters or Craig's List because
lots of people are tossing them for LCDs, so the CRTs tend to be in
good condition. I've found them so plentiful that I no longer bother
with anything smaller than 19".

It's very unlikely that the steel band has loosened because it seems
to be welded together, and if it did loosen, I'm pretty sure that the
picture tube would fall inside and maybe implode/explode.
As far as I can see from this diagram for an AOC/Envision EN-775 or
EN-760 monitor, there's no separate outer flat cover for the screen:

What's an Envision EN-710 like? I was curious because I
have an Envision something-or-other 19" still, but looking
through one section of my rebate archives I only see a
listing for an EN-710e that I bought from Staples for $30
AR, but I can't remember it at all which must mean I had
bought it to be bundled with some system I sold, or that I'd
given it away to a relative.
The 19" Envision I still have is hardly impressive, it was
blurry compared to the Trinitron monitors I normally used a
the time and it's flat tube meant it had a curved tube
sitting behind a flat piece of glass - the difference
between it and a real flat tube was obvious, and yet I
didn't mind so much because it too had a large rebate
attached to the purchase price, plus it wasn't my primary
monitor.

Speaking of which, I need to throw away a lot of old CRT
monitors, though most of them have dimmed over the years to
the point where they're hardly usable. IMO, a lot of people
aren't dumping monitors just to move to a CRT, they're doing
it because the monitor isn't very usable anymore. Maybe I
am only thinking of the DIY crowd, instead of those who buy
a new Dell that came with a bundled LCD for not so much
addt'l in price.

I agree the band wouldn't be loose, otherwise there would be
a clear gap between the outer glass and the plastic.
However my 19" Envision clearly does have an outer flat
glass panel that is not part of the CRT tube itself. I was
very disappointed when I first saw it was designed this way
yet advertised as a flat screen, but for the after-rebate
price plus the hassle of returning it, I accepted it for
secondary system use. I used it so seldom that today it
still works fine, eventually I'll replace it with an LCD
while it still works because I couldn't find anything
positive about it, and yet for the AR price it still serves
it's purpose well, affordably as just something to turn on
attached to a KVM for several systems in the basement.
For a short while I had a new 22" LCD I'd bought next to
it... there just isn't any comparison, that 19" Envision is
like living in the stone age and looking through glasses
with grease smeared on them.
Maybe I'm just biased, when I read of someone touting the
virtues of CRTs, and myself always using Trinitrons and even
then finding even the worst LCDs superior, I can't help but
think that faster response time and greater contrast mean
nothing if the pixels don't even show up as intended instead
of being blurred.
Granted, this is a VERY subjective thing, but I wish CRTs
had never existed, that we'd started out using LCDs and
they'd just advanced over the years.

Sorry, I meant EN-710e. Here's the service manual Envision e-mailed
me when I asked for the EN-710e manual:
That service manual explains how to access the hidden adjustments,
like vertical linearity and color balance, and it also gives detailed
repair information, but for some reason the schematics were left out.

My EN-775 looks sharp, but my EN-710e was fuzzy at 1024x768 if the
refresh rate was above 60 Hz.

Even after the Screen control on the flyback or the sub-brightness
control was turned up?

Out of around 15 monitors I've taken from the trash, most worked fine,
four I couldn't repair with my limited skills (or limited money), and
the rest needed only tweaking, resoldering, or some new capacitors.

I guess that's the advantage of LCDs drawing their pixels practically
right at the screen instead of from a foot behind, as CRTs do. OTOH
some CRT monitors come from the factory with only so-so convergence at
the edges, and the focus there can be improved by tweaking the dynamic
adjustments and gluing additional magnets to the CRT or yoke.
