         We just bought some new flat panel displays for work the past few 
months, and the technology has increased siginifgantly in the past couple 
years.

         One little "detail" to look for is the Contrast Ratio.  I am not 
exactly sure how it works, but from a pedestrian & uneducated point of 
view, the higher the contrast ratio, the better the image, especailly in 
dynamic range.

         For example, at work, we have Samsung 191N monitors, and at the 
local best Buy, they have what appears to be the exact same monitor, but if 
you read the fine print, its a "192N"

         While the dot pitch and every other detail and statistic appears 
to be identical, the one difference is the contrast ratio - ours is 
something like 600:1 or 700:1, whereas th eoens at the store are 350: or 
400:1 (doing this from memory).

         Again, I am not technical enough to explain what the difference 
is, but even from memory, you can see that the dynamic range on our 
monitors at work (which cost siginifgantly more too, BTW) is much better, 
or from a purely perspective point of view, images look "deeper" if that 
makes any sense.

         I will go out on a limb and say, yes, you can get flat LCD sreeen 
monitors that match a good CRT monitor - BUT - it might be  a special order 
(we had to order ours in special) - and, the price is going to be pretty 
high.  Whereas a "regular" LCD monitor you see in the  average store is - 
oh - say on average, double the price of a comparable CRT monitor, a really 
good LCD monitor with a high contrast ratio will set you back maybe three 
times the price of a comparable CRT monitor.  Or more.

         I think it will be a few eyars more before pries for really good 
LCD monitors come into line, but when you get a really good, they are amazing
