Eizo CG222W display analysis
- The following tests were run at 110 cd/m2, 6100 K, Lstar unless otherwise noted.
Color gamut
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).
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.
OTHER
- Size: 18.5 inches by 11.75 inches (actual display area).
- 1680 x 1050 native resolution
- On board buttons will not work while CN software is open.
Back Panel
Here is the arrangement of the back panel, left to right, as looking from the back:
- Power in | (2) DVI ports | USB In | (2) USB Outs. (No USB on the side.)
Looking from the front
- Ambient light sensor ; Lock ; S ; M ; A ; o ; < ; V ; A ; > ; power ; Blue light.
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:
- The largest delta E difference between any point on the screen is 2.63 from the upper right to the lower left corners. (Other displays in this category were in the 5's or more.)
- 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.
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:
- 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.
