not all LCDs are made equal, even when all of them say "Active matrix 
TFT". Currently (S-)IPS panels are probably the best for colour 
corrections/photo editing, followed by PVA and MVA. Most of the common 
LCDs are made using basic TN technology which is quite inferior to the 
above mentioned due to significant colour shifts when viewed from an 
angle among other things (fine for the office stuff though).

If tech specs mention viewing angles 178/178, it's most probably PVA/MVA 
based display, 170/170 is characteristic of IPS. Latest TN panels offer 
160/160 but I'd say it's more like 150/130 as the visible difference is 
considerably higher.

Of course there are some other important aspects like quality and 
uniformity of the backlighting or internal gamma/LUT adjustements 
capabilities but the quality of the screen is primarily determined by 
used panel technology.

Cheers,

Peter

Calibration using fixed black and white luminance points fixes the
contrast ratio, if you are aiming to emulate the sRGB as your monitor
device space then the value you should be setting for white luminance
is about 80 cd/m2. At that luminance the better CRTs will be able to
manage around 0.2 cd/m2 and most TFT will manage around 0.4 cd/m2 or
0.2 cd/m2 for the better high contrast models. A luminance range of
0.2 to 80 cd/m2 is 1:400.

It a pity stuff all people seem to appreciate these fundamentals.

I'm no expert, but contrast ratio is important to me. It limits what I can 
see as far as dynamic range (of intensity). Viewing angle is important too, 
because with the less capable monitors, what you see can change drastically 
with viewing angle. Large viewing angle is good. Also, I like being able to 
adjust each color individually (not just what the manufacturers give you as 
their idea of color temperature).

As to response time, it's only important to me because I also watch Hi-Def 
movies on mine.

They ALL look better in a dark room.

My concern is that if the native contrast is very high, then it might not be 
able to be adjusted to a level that is suited to image editing.
My secondary monitor is a Samsung 192N, which apparently has a 700:1 
contrast ratio as native. I find it is rather punchy for editing, which is 
why I am still using my old Samsung 955DF CRT monitor as my primary.
As far as calibration goes, I'm not terribly concerned about what other 
people see, since I can't control their calibraton. All I can do is keep my 
system calibrated, which is somewhat of a compromise since I need my system 
to coordinate with what is coming off the lab, as well as my inkjet printer 
and still put something on the web that is viewable witout hurting to many 
sets of eyes.

That depends upon the range of adjustability provided by the contrast  
adjustment control, and how well the calibration for color fidelity  
can be managed given a sensible contrast and brightness setting.

The point of a quality monitor display is that it can display the  
range of tones and colors accurately to be used as a reference for  
doing photographic image processing: making web and print versions of  
photographs for display and distribution. The fact that other  
monitors might have difficulty displaying what your reference display  
renders with good fidelity isn't relevant. What's relevant is that  
such a monitor allows you to edit and view your work with consistency  
and quality.

If contrast is adjustable, doesn't this compensate for the contrast the

Low contrast. A lot of monitors are very high contrast, upwards of 3000:1. 
Great for games, but harsh for phtos.
The nice Eizo monitors that are designed for graphic arts are 600:1 or 
thereabouts.

I'll second that.  I don't own one and know next to nothing about the 
specs, but the Apple Cinema displays are some of the best looking 
monitors I've seen.  Were I in the market one of those would be a 
serious consideration.

I'm sure others will pipe up with a bunch of specifications and  
technology notions, but in practical terms I've found the Apple  
Cinema Display 23" that I'm currently using to be superb, and barely  
less in quality than the EIZO professional flat screen display of  
similar size and double the price. That said, the Samsung SyncMaster  
205bw that I used as a temporary backup when my power supply bit the  
dust last Fall, once properly calibrated with the Eye One Display 2,  
produced on screen viewing and editing quality only marginally less  
excellent albeit in a much cheaper, less stylish enclosure. And that  
one cost 1/2 or less what the Apple monitor did.

This leads me to suggest that if you get any of the better, decent  
displays available today that run in the $500 to $800 price class AND  
get a good calibration/profiling utility, you will have a perfectly  
acceptable, useful monitor. The calibration/profiling tools are the  
real discriminator.

And that said, one thing I do not like is the recent trend to  
displays with a glossy finish. Just like glossy prints, they drive me  
nutty with reflections and cause the photographs to become overly  
saturated and contrasty in appearance.

Some quick monitor info

It seems my CRT monitor is about to bite the dust - it's starting to

Any quick help would be appreciated as I'm no doubt having to do some
