Hello,
 
I am currently thinking of buying a TFT monitor. What properties should
I take into account when deciding which one to buy? Obviously, the
physical size. I am doubting between 17" and 19". But I've heard a 17"
TFT monitor displays more than a 17" CRT monitor. Is this correct?
 
What is the difference between TFT and LCD?
 
At [0], different monitors are offered. Prices for 17" 1280x1024 25ms range
from €429 to €650. The difference I see is that the latter has "700:1,
270cd dvi, zilver". When do I notice this?
 
I use my computer to watch television, and read and write texts. What
should I choose?
 
yours,
Gerrit.

"TFT" means "thin-film transistor," which is the technology used
to create the active-matrix array on modern monitor LCDs.  Virtually
all current monitors are of the active-matrix TFT type, so within this
market there is no difference.
 
A 17" LCD monitor DOES provide a larger active area than a 17"
CRT, as it has been traditional in the LCD industry to base the diagonal
size measurement on the active area, while CRT diagonals give the
overall CRT size.  A "17 inch CRT" will typically have an active area
that's about 15.5" or so in diagonal size.

700:1 is the contrast ratio; within reason, higher is better, although
in recent years these specs have become almost meaningless due to
the tendency to quote only "dark ambient" numbers.  Anything over
300:1 in actual delivered contrast would be outstanding, but very,
very few products actually provide this level of performance in normal
office or home lighting conditions (contrast in these situations is
dominated by the reflection of ambient light from the screen, not
from the inherent white/black contrast of the display device itself).
270 cd/m^2 (read "candelas per square meter", also sometimes referred
to by the older term, "nits" ) is the measure of the luminance or
"brightness" of the display (i.e., how bright white areas are at
maximum).  This is actually a fairly average level; higher specs may
be found, but again take any published specs with a grain of salt - it's
far better to actually SEE the display, and go with what YOU like in terms
of the overall appearance.  "DVI" is the current digital interface standard;
it may be useful for you, but only if you have a video source providing a
DVI output.  I don't know what "zilver" means, unless this is a typo and
it meant that the case color was "silver."

The best advice is to try out the monitor with the sort of images you
commonly use, and choose the one that YOU think looks the best.
For TV use, you'll want a fairly fast response time - 25 ms or better should
be the absolute minimum, and you'll see a distinct improvement if you can
get to 16 ms or less.  TV viewing also generally calls for high brightness
(over 300 cd/m^2 would be good), and good color performance - if you
want accurate color in your TV images, the monitor should be able to
be set to a white point of 6500K (it will be listed in this form as "color
temperature" ), and the larger the color gamut (expressed as a percentage
of the standard NTSC or EBU gamuts) the better.

I can't add much to Bob M's excellent response, but here goes.  You
might want to consider a TFT with dual CPU option.  That's a TFT with
both analogue and digital inputs and you can connected and display 2
computers on 1 monitor.  Also, a swivel screen may be useful.  This
means you can position the monitor vertically to display more
information without using scrollbars.  Be careful of dead pixels.  
These are pixels that stay on or off all the time.  Sometimes you need
at least 5 dead pixels to get a refund/replacement.  I guess the
cheaper monitors will have more chance of dead pixels.  You might want
to consider pixel pitch and resolution.  Most TFTs only work best at
their native resolution.

I've just purchased my first TFT today.  I went through the headache
of visiting numerous computer stores to examine monitors and also read
dozens of reviews.  In the end, I bought an 19" LG L1920P.
 
It has 2 USB ports called upstream and downstream.  I'm not quite sure
what the possibilities are with these ports as the manual is very
brief.  If anyone can inform me, please do?
 
It has 2 video inputs, analogue and digital.  I have it connected to
the digital input as my graphics card has a digital output.  Viewing
high resolutions images on this monitor is a real pleasure.  Browsing
text or surfing the net is also a pleasure due to the sharp text.  I
tried a dvd on the monitor when I was in the store and it looked
really impressive.  My only disappointment so far is playing 3D
snooker.  The monitor ghosts a lot when the snooker balls are rolling
across the table.  I don't know if switching to analogue, which uses
75hz, may improve this.  Digital runs at 60hz.
 
I had a look at some other monitors before buying the LG L1920P.  For
example, I looked at a couple of LG 17" monitors, the L1710S and the
L1720B, but the text on those looked really small and difficult to
read.  They were priced at £299 and £349.  When compared to the
L1920P, they look terrible, so it makes sense to dump the extra coin
and get the one with the nicest display.  Another thing, I checked the
L1920P for dead pixels using LCDTest and not a single dead pixel was
found.  I've seen dead pixels on cheaper models.

Yes, it makes a lot of sense.  Unlike a CRT, an LCD doesn't have thick
piece of glass between you and the graphics, and that makes a big
difference.

Oh.  Glass.  How horrible.
 
Unlike an LCD, a CRT doesn't have a polarizing filter between you and
the graphics, and that makes a big difference.

Many CRTs have polarizing filters?  I have an add-on one, and AFAIK there's
no warning about not using it with certain monitors (they might all be
aligned the same say).

Of course not.

It wouldn't make much sense to place an add-on one in front of an LCD
monitor.  If you do, you'll know right away if it's not aligned with
the monitor's filter, as you wouldn't be able to see anything.

It's older than LCD monitors; that's why there's no warning against using
it with one.
 
You can get some interesting effects with that and a digital watch, though.

Well, let's see - this means that you won't be able to
use an LCD monitor with certain polarizing sunglasses.
Outside of that, what "big difference" did you have in
mind?

I'll tell you, Bob, right after you tell me what "big difference" the
thick glass on the front of a CRT makes.
 
Doesn't surprise me at all, Bob, that you'd intentionally ignore the
point I was making (that spam_eliminator's statement was ridiculous),
and hypocritically attack it, with no mention of what spam_eliminator
said.

Well, that's proof that they're better right there!  Not.
