This is a big selling point.  This display encompasses the LaCie 324 wide gamut monitor, and almost covers all of AdobeRGB.  The actual gamut volume will vary depending on the software and instrument used for measurements.  (ex: 1,182,000 gamut volume)

Color is warm toward center of vision, cooler to the outside edges.  Perhaps more so on the up & down off axis than the left-to-right axis.

No problems.  Colors and density seem to stay the same within a reasonable angle of view compared to most other LCDs.
-
* One customer has reported trouble seeing shadow detail because of angle-of-view problems.  According to him, the shadow detail is visible when viewed head-on to the display, but when the viewing angle is changed even slightly the dark areas appear "lighter" and it is hard to determine what is true shadow detail in the image, and what is a characteristic of the angle-of-view change.

==Brightness==
-
I did not test the minimum or maximum brightness of this display.  It is capable of getting very brightThe internal graphics processing allowed it to get as dim as 120 without significant problems, although the LUT curves show a very sharp decrease in the curves in order to achieve this.  I could detect a small amount of banding.
+
The display is designed to run between 60 and 80 cd/m2At 60, there are no problems with shadow detail, banding etcIn order to run at greater than 100, you need to click a warning box during profile creation (in Color Navigator) to extend the upper range.  This allows the user to set the brightness anywhere they like up to as bright as it can goThe highest I was able to run our test model was 238.9.

==Calibration software - Eizo ColorNavigator==
-
 
+
The ColorNavigator software is required for proper calibrating of this display, as only it can access the internal graphic processor in the display. This works wellThe CN user interface is a little more complicated than other software packages to understand, but has all the features that are needed.
-
==Calibration software - Blue Eye Pro==
+
-
It does not appear that the Blue Eye Pro software comes with the monitor, however I was able to download the latest version from the LaCie website and use it with the i1D2 and the Optix colorimeters.
+
-
* This software is laid out very simplyIt's easy to use.  There's not a lot of complicated choices to make, and yet it seems to provide all the necessary choices:  (Version 2 or version 4; LUT or matrix; custom white points and black points available.
+
-
* It makes adjustments to the internal video card, and leaves the computer's graphics card mostly flat.

The automatic DDC correction option within ColorEyes Display Pro appears to work.  However, it operates differently that the LaCie softwareWhile the Blue Eye Pro software leaves the computer's graphics card mostly flat, the CEDP writes on both LUTS:  the monitor's and the computer's - and makes some dramatic changes on both.  Still, the resulting profile looks good to the eye.
+
ColorEyes Display Pro is a popular third party profiling software that can sometimes be used instead of CNAt this time, CEDP does not interface with the DDC capabilities of this monitor.

==Rotation==

This display can be physically rotated between vertical and horizontal.  There is no "automatic" image rotation in the software though.
-
* There is no vertical/horizontal rotation of this display.
+
This display raises and lowers about 6 inches, tilts from upright to laid back a bit, and pivots about 35 degrees from left to right.  (The base stays in one place while the display pivots.) The bottom of the display is about 6 inches off the table when in fully down position.
-
* This display raises and lowers about a foot, tilts from upright to laid back, and pivots about 350 degrees from left to right.  (The bases rotates around to make it easy to "turn it" for other people to see.)

I am able to distinguish shadows of 5 L value difference, and it could probably have gone lower, although I did not test it.

I am able to distinguish shadows of 1 L value difference; highlights of at least 2 L maybe better.  
==Banding / grayscale==
==Banding / grayscale==

I can see a very small amount of banding (luminance) or posterization in the gray background behind the pitchers in the CHROMiX Frontier test image.

There is no banding that I can see, even at 60 cd.  The gray looks very neutral.

The uniformity of color and density across the screen is the best I've seen on these newer, less expensive, high gamut displays:

 +
*The average dE difference is about 1.0. 
 +
 
 +
They make a big deal out of this in their literature, and the display came with a sheet showing the results of the factory analysis of the uniformity tests they did.  They are advertising that they have no more than 3 dE throughout the display - and my tests confirm that.

This is comparable but maybe a ''little bit'' worse than the other wide screens I've looked at recently (Eizo CE2411, CE240W, NEC )

==Cons==
-
Basically, the average is from dE 1 to 3, with the worst being about 4 to 7.
+
Since there is so much to like about this display, there are too many pluses to mention.  On the other hand, it's hard to find anything to fault about it.  The following "cons" are rather inconsequential, but I mention them for what they are worth:
 +
* It "feels" smaller than some other stretched wide monitors.  The top to bottom dimension of the display area on the 222 is 1/4 " shorter than my Norwood 19".  So it's actually a tiny bit shorter than an average 19 inch display.
 +
* The top brightness is a bit low compared to other models.  While we would ordinarily never want to operate anywhere near 238, other models can get to 300 or more.
 +
* It has no speakers, no USB ports on side, no auto rotate of the images in the software.
 +
* The DDC does not interface with Coloreyes Display Pro at this time, so you have to use Eizo's Color Navigator software to calibrate this display.  This is not a problem, since Color Navigator is very good also, but some people like to have the choice to use Coloreyes Display Pro also.

Eizo CG222W display analysis

The following tests were run at 110 cd/m2, 6100 K, Lstar unless otherwise noted.

Color gamut

Gamut comparison between the 222W, LaCie324, AdobeRGB and a typical LCD display

This is a big selling point. This display encompasses the LaCie 324 wide gamut monitor, and almost covers all of AdobeRGB. The actual gamut volume will vary depending on the software and instrument used for measurements. (An example of the gamut volume from one of my profiles is: 1,182,000) By comparison, the "Norwood" profile below is typical of normal-gamut LCD's and CRT's that correspond to sRGB.

Evenness

Visually this display looks uniform.

Angle of view

No problems. Colors and density seem to stay the same within a reasonable angle of view compared to most other LCDs.

Brightness

The display is designed to run between 60 and 80 cd/m2. At 60, there are no problems with shadow detail, banding etc. In order to run at greater than 100, you need to click a warning box during profile creation (in Color Navigator) to extend the upper range. This allows the user to set the brightness anywhere they like up to as bright as it can go. The highest I was able to run our test model was 238.9.

Black Level

Our test display was able to get down to .14 cd/m2.

Internal LUTs?

Yes. 16-bit Internal LUT. Controlled through Eizo's ColorNavigator software (included).

Calibration software - Eizo ColorNavigator

The ColorNavigator software is required for proper calibrating of this display, as only it can access the internal graphic processor in the display. This works well. The CN user interface is a little more complicated than other software packages to understand, but has all the features that are needed.

DDC connection with CEDP

ColorEyes Display Pro is a popular third party profiling software that can sometimes be used instead of CN. At this time, CEDP does not interface with the DDC capabilities of this monitor.

Rotation/Movement

This display can be physically rotated between vertical and horizontal. There is no "automatic" image rotation in the software though. This display raises and lowers about 6 inches, tilts from upright to laid back a bit, and pivots about 35 degrees from left to right. (The base stays in one place while the display pivots.) The bottom of the display is about 6 inches off the table when in fully down position.

Highlights / Shadows

I am able to distinguish shadows of 1 L value difference; highlights of at least 2 L maybe better.

Banding / grayscale

There is no banding that I can see, even at 60 cd. The gray looks very neutral.

Uniformity details

The uniformity of color and density across the screen is the best I've seen on these newer, less expensive, high gamut displays:

They make a big deal out of this in their literature, and the display came with a sheet showing the results of the factory analysis of the uniformity tests they did. They are advertising that they have no more than 3 dE throughout the display - and my tests confirm that.

Cons

Since there is so much to like about this display, there are too many pluses to mention. On the other hand, it's hard to find anything to fault about it. The following "cons" are rather inconsequential, but I mention them for what they are worth:
