How do 19" CRT monitors compare to 19" LCD?

How would you compare a 19" CRT monitor to a 19" LCD one? Which is
sharper and has higher resolution, or are they about the same?

 

Differences: about 60 pounds (27 kg) and $500 USD (400 euros) and a

Expensive ones? Maybe the CRT.
Medium price? Maybe the LCD.

 

A 19" CRT monitor is a lot heavier!

You really have to compare specific models of each. There are high and low
quality versions to be had in both types. Specifications can tell you some
things but not all. There's nothing like going to a store that has a range
of both and doing side by side comparisons.

For example, "Sharper" can mean lots of things if you're being informal,
including how well the monitor renders black..

 

The 19 inch LCD would be about equivalent to a 20 inch CRT. The LCD
monitor would be about 50 to 60 lbs lighter. There are many advantages
of using LCD monitors, especially the amount of space that it takes up
on the desk. LCD monitors give off much less heat and radiation in to
the environment.

As the LCD monitor ages, there is no degradation of its accuracy for
colour balance, as like with CRT monitors. There are no visible errors
from misconvergence, purity errors, focus errors, linearity errors, and
pin errors. LCD monitors cannot have burn in as like CRT and Plasma
displays. LCD monitors can however, have pixel sticking problems if
something is left up on it for many hundreds of hours. Unlike the other
technology displays, the LCD monitor pixel sticking problem can be
reversed.

LCD monitors do not radiate any ultraviolet radiation, have very little
electromagnetic radiation, and have no X-Ray radiation. LCD monitors do
not have any flicker that can give eyestrain after many hours of use.
LCD monitors can be viewed in a lit environment, while CRT monitors are
best viewed in a darkened environment. LCD monitors are about 60 to 80%
more efficient for power consumption. A typical LCD monitor can consume
about 45 to 55 Watts of power, while the equivalent CRT monitor will
typically use about 150 to 180 Watts of power. In business
establishments, it has been found that users of LCD monitors are
requesting less sick leave, due to headaches or fatigue. There is much
less danger from electromagnetic radiation from LCD monitors for
pregnant women, as suspected from CRT monitors.

The only thing that may annoy some users of LCD monitors, is that there
is the chance for bad pixels. Some people have a low tolerance for bad
pixels. Each manufacture has their policy for bad pixel error acceptance
for warranty exchange. LCD screens must not be touched with any
pressure, because they can be easily damaged. Putting your fingers, or
pens on the screen for pointing will most likely cause permanent damage.
When cleaning the LCD monitor screen surface, it must be done very
carefully. LCD monitors must be run in their native mode for best
picture quality. LCD monitors are generally slower responding than CRT
monitors, but have been improved more and more every year. When the LCD
monitor is viewed in a darkened room, the definition of the black
details may not be as good as the CRT type. The greater the cost of the
monitor, the better the contrast ratio and performance. LCD monitors
have a lower contrast ratio than the CRT or Plasma types, but they are
being improved as the manufactures find ways to do so. There is a
compromise between contrast ration and speed.

Personal experience: The 19" LCD monitors I've looked at all seem to be
1280x1024 max. I do that with my 17" CRT. If I moved to a larger (in
inches) monitor it would be so I could get higher than 1280x1024. I'm not
looking for a bigger representation of the same stuff; I'm looking for a
larger screen to get more stuff *in*. So the 19" LCDs don't float my
boat even though their prices are getting pretty decent.

 

Your graphics card plays the important role, and if equipped with
a DVI output, you'll be at least "future-proofed" if you opt for a
monitor with a DVI input, which invariably will be LCD.

picture quality.

From an earlier post. native mode is very important. Each LCD monitor has
a native mode or resolution which they are designed for. You can not change
the screen resolution and have as sharp of display (most noticible on print
or characters) like you can with a CRT. However, all things being equal, IF
the resolution is what you want (i.e. 1280 x 1024) and the cost is anywhere
close (say $100-$150) go with the LCD. My company recently made the change
from CRT's to LCD because in the final analysis, AND counting shipping,
LCD's were actually cheaper in the long run that CRT's.

 

Glass screens (CRT's) are always clearer unless you buy junk. They also
don't have fuzzy font issues when you don't use them at their native
resolution like many LCD panels do.

When it comes to CAD or Graphics work I use a CRT because an LCD just
doesn't cut it for clarity.

 

Soon you won't have a choice. CRT monitors have been going out of
production. If you have gone shopping lately, take a look at the choices.
Some stores don't even handle CRT monitors any more.

Have you tried any real high end LCD monitors?


The link below shows LCD monitors that can be used for any type of
professional applications. These are the level of monitor that we use in our
facilities for photo finishing and production work.

CRTs tend to have a greater range from darkest to brightest parts of the
image, which gives the impression of 'better sharpness'. However, I have
never seen a CRT that is as close to truly 'flat' as an LCD.

 

LCDs can certainly manage finer resolution than that; I'm using a laptop
with a 17" 'widescreen' 1440x900. The 'generic' Linux driver for my
graphics card offers a maximum resolution of 1920x1200, so someone must
think such LCDs exist.

I have a Toshiba libretto with a 7.2" LCD whose native resolution is
1280x768 - so a 17" screen should be able to squeeze in more than twice as
many pixels in each direction, if the design can be scaled up.

 

CRTs tend to have a wider luminance range, ie 'more contrast', so they
look a bit 'sharper' - all other things being equal, which of course they
seldom are )

The 'resolution' of a display is a seperate thing from it's physical size;
you need to consider both.

CRTs generally cope better with being set to a resolution that is lower
than the maximum they are capable of; that can be very useful if you want
a quick way to 'magnify' things, eg if one of your users has less than
perfect eyesight. LCDs told to use a lower resolution tend either to get
'blurry' or to simply make the display smaller, with a black or blank area
that isn't used at all.

The quoted size of a CRT is usually slightly larger than the actual usable
area of the screen, so a 17" LCD could have as large a display as an 18"
CRT. (The size measurement is usually diagonal, in case you didn't already
know that).

 

No.

 

Yes, I have, and if I take an LCD and CRT of the same quality, the CRT
is always clearer, better, etc... We have many different LCD units in
our clients locations, work with many different quality of units, even
some over $2500, and I still see the same thing in them - a medium
priced $500 CRT will present a better image than an LCD under $700. Even
some cheap $250 CRT units out perform expensive LCD units.

 

And Flat, truly flat, doesn't mean must to most users. CAD users don't
care if the screen is perfectly flat, neither do programmers, and
neither do graphics people - as I've done them and worked with many of
them, I can assure you that most screens (CRT) can be near flat, and
it's enough that the flatness of an LCD doesn't make up for its lack of
quality.

 

In JANA spewed forth:

Very true. When my CRT died, the local stores had almost no CRTs whatsoever.

 

In Blinky the Shark spewed forth:

I've seen the same limits in desktop LCD displays. I wonder why? The laptops
at work (15.4" and 17" screens) have 1600x1200 resolution. I wish I could
get that on my desktop. I'm with you - I don't need my data LARGER, I want
more of it on the display. Of course, when working with text/numbers, it can
be zoomed/scaled to assist with that.

 

In Leythos spewed forth:

I do both CAD and photo retouching on my CRTs and LCDs. Personally, I know
the lines are straight, because I drew it that way. And it will be straight
when the plotter or printer puts it on paper. So I agree - the flatness of a
screen means very little.
