Thanks, unfortunately they don't do CRT repair, and it appears the
business they referred me to is out of business. I might check with
a guy I used to bring electronics to in Austin, who was doing lots of
monitor refurbs around 2003.
I checked out 22" and 23" LCD monitors at Office Depot, yesterday.
My opinion remains that "widescreen" computer monitors less than 30
inches are "vertically challenged". And a 30 inch widescreen monitor
is fine if your desk is little more than a computer monitor stand,
like my desk at work. But if you're trying to squeeze one more
monitor into your non-supersized-home or apartment, the old 4x3
tallscreen screen format makes more sense. I have 3 big 16x9 HDTV's,
including 2 LCD's, if I really want to watch movies, which I don't do
that much, actually.
Also, fwiw, you get more actual square inches of screen for a more-
square shape like 4x3, given a fixed diagonal. But the real issue is
how much screen you can fit into the space you actually have. Our
dwellings generally have room to burn in the vertical direction but
less so in the horizontal.
So that, and my preference for nice color and static contrast ratio
have led me back to getting another CRT. You can find 'em, though
not easily, online. From Dolphin Enterprises I ordered a refurbished
Viewsonic P810 for $174. That wasn't my first choice, I wanted a
more up-to-date G225fb, but it's the big Viewsonic they actually had
in stock, and the price is very reasonable, same as for a teeny LCD.
And, it makes my second P810. My first P810 is still going strong
for Windows and Amiga in my computer room (whereas the new P810 will
go on my more-often-used Mac system in the kitchen, because I
actually spend more there browsing the web than in my overstuffed
computer room). I paid $1900 for my first P810 in 1999 and now I'm
getting my second one for less than 1/10 that (well, plus shipping).
It has always been bright and crisp and apparently they're pretty
reliable, as shadow mask monitors generally seem to be. (For some
reason, trinitron monitors generally seem less reliable, it may
either be the more complex electronics or the companies involved who
generally push trinitron screens for graphics performance and shadow
mask for general purpose durability. Viewsonic monitors are
generally made by Panasonic which is more known for reliability than
pushing the performance envelope.) And having two of the same thing
potentially makes future repair easier. A newer model might have had
digital connections, higher resolution, etc., but at greater cost and
potentially lower reliability.
I also see the advantage of the 16x10 format vs 16x9. It's not the
perfect size for widescreen movies, but for computing it gives you a
nice 11% increase in height. Unfortunately, the insist on giving you
what seems to me to be a stupid format: 1680x1050. What they should
give you IMO is 1920x1166. Then you could see 1080p high definition
video (1920x1080) with perfect pixel mapping, and just a black bar on
top or bottom. Perhaps they're afraid to do 1920x1166 to call
attention to the poor static contrast of most LCD, better to cut the
picture a bit and hide that. Or, alternatively, they could give you
perfect double pixel mapping for 4x3 television (hello you tube) with
1536x960. BTW, 4x3 is the same as 16x12, so you can see where 16x10
fits in.
So you go to office depot (or most anywhere else) and view their 16x9
and 16x10 monitors, but then when you go up to the sales terminal,
what kind of screen they have?
