Where does the light come from that they filter?

Phosphors.

No. Not phosphors. LEDS ( well actually transistors if you want to
split hairs).

Thanks for telling me the light source is LEDs/transistors. All the
time I thought there were compact fluorescent lamps (containing mercury
and phosphors) behind the LCD panel.

I meant cold cathode fluorescent lamps, obviously. I was in a hurry....

The LCD monitor has everything going for it, except for its contrast ratio,
reaction speed, and viewing angle restrictions. <snip
I've been using an LCD monitor for the last 3 or 4 years. Recently, I
decided to get a new monitor. When I started shopping, I had taken it
for a given that I would get another LCD. After all, they're lighter,
they take up less space, consume less power, they are now ubiquitous,
and you don't feel like your face has got sunburn after a few hours
sitting in front of one, right?

I went into a big box store and they happened to have a cheap, no name
brand CRT monitor sitting in a corner at the end of an aisle
containing dozens of LCDs. That was the only CRT in the entire store.
After spending about half an hour looking at monitors, making sure the
graphic cards were set to match the native resolutions of the LCDs, I
came to the conclusion that the image quality of a CRT (even a low-end
one) is far superior to that of even the best LCDs on the market
today. It's particularly noticeable when viewing photographs. CRTs
have a smoothness that LCDs lack; they're not "grainy" like LCDs.

When you use an LCD day after day, you get used to it and tend not to
notice, but looking at a CRT and an LCD side-by-side, I was stunned at
just how poor the image quality of an LCD actually is. That must be
why many graphic designers still prefer CRTs.

Another advantage of CRTs, I've been told, is that they provide a high
quality display across all the resolutions they are capable of,
whereas LCDs only give their best at their native resolution. That
could be a factor for people who like to switch between different
resolutions.

At any rate, it's a moot point, since it probably won't be possible to
buy a new CRT monitor within a year or two.

Yes, you will, just not at the scale you used to. CRTs can still do things
that LCDs can't. Little things like higher resolution and better colour
rendition.
Little things like that, which the masses with more money than sense don't want.

That only leaves the CRT market at the higher end. Fine with me, as LCD
still doesn't cut it for me.

Obviously I agree with you about CRTs having unique attributes that
LCDs are likely incapable of reproducing, but my experiences with
trying to find a brand-new CRT monitor in the last few weeks haven't
been encouraging.

I honestly believe, based on what I've seen, that 2 or 3 years from
now there will be as many companies manufacturing CRT monitors as
there are companies manufacturing open-reel analog tape decks today
(that is to say, zero).

That only leaves the CRT market at the higher end. Fine with me, as LCD
still doesn't cut it for me.
I've heard mention of the high end market for CRT monitors a few times
now, but haven't actually come across any high end models for sale
anywhere. Are you sure this market still exists?

I've posted a question relating to CRTs in some other newsgroups, and
it seems photographers, graphic designers, video editors, etc., are
either hoarding CRTs or switching to high end LCDs at this point.
You'd think that if high end CRTs were still being made, some would be
switching to those instead.
