LCD/TFT vs. CRT

[Lior Bobrov]

Hi .

I use a Deal-15'' digital CRT monitor for 7 years (since Sep. 1996) .

I consider replacing it with and LCD 15''/17''/18'' , or a CRT 17''/19''
monitor .

I wonder if LCD monitor has no radiation at all - there are places on the
web that say
LCD TFT monitors have no radiation at all , when other sites on the web
tell that
LCD TFT monitors has much less radiation than the CRT monitors .

I have already encountered a site which tells about zero-radiation LCD
monitor .
This website address is http://www.milligauss.com/ .

If you've already heard about known manufacturers (such as MAG, LG ,
Samsung)
which produce such zero-radiation LCD monitors , please write them down ,
plus
these monitors models .

Are LCD monitors really preferable than CRT monitors (especially if I need
to work
with the screen for some hours a day) ? I suffer from eyestrain when
working with
my 15'' old monitor .

People here who use LCD :
please write down the main advantages and disadvantages of LCD TFT monitors
,
comparing to CRT 17''+ monitors . (Also, please specify some quality models
+ manufacturers) .

People here who use CRT 17'' and above :
please write down the main advantages and disadvantages of CRT 17''+
monitors ,
comparing to LCD TFT monitors . (Also, please specify some quality models +
manufacturers) .

Thanks in advance ,
Lior .

In your situation where you are using the monitor for long periods of time
there is a disadvantage and advantage to both an LCD monitor and CRT.

It is true that LCD's give off little or no radiation because it works on
liquid crystals changing orientations whereas CRT's fire electrons
(radiation) at a screen. So in that sense LCD is better.

As for eyestrain, well the thing you want to look for is the refresh rate.
The higher the refresh rate the better, and CRT monitors can achieve higher
refresh rates then LCD's. So in this sense CRT's are better.

If you are leaning towards a LCD monitor check out Viewsonic's since they
have one of the highest refresh rates of any LCD monitor that I have
personally seen (about 70-75 Hz for some of their models compared to 60 Hz
for other LCD's).

Hope that helps

Due to differing technologies the refresh rates can't be directly
compared. An LCD usually appears flicker-free at it's higher
supported refresh rates.

A more common point of interest is often the user's preferred
resolution... While a good CRT can effectively change to higher OR
lower resolutions without significant blurring (until near it's upper
limits), the LCD has only one native resolution which MUST be used for
the picture to look good and crisp. Using this native resolution is
IMHO, better than most CRTs, but any other resolution would be worse
than a CRT of similar price.

So wow will a 15'' tft look when a running a text terminal like a
linux console?
does it means that the linux kernel or at least the graphic driver
must know about the best settings so that the image will be at is best
quality?

One thing that i don't understand and i'm going to buy a tft in a few
days is way they recommend to run a resoultion like 1024x768 @ 60Hz
instead of 75Hz
at least Philips, Samsung and a few recommend this, weird now??

I just can't figure out why ... Any Help?
Thanks in advance
