If only one (1) of 7 monitors the picture quality was actually as advertised, namely neutral image, high contrast, smooth anti-reflection coating. Unfortunately, this is a copy had the disadvantage that the film was poorly applied and was therefore observed at the edges Backlight Bleeding. I conclude that it was a PLS panel from Samsung at this specimen.
For the other six (6) the contrast was significantly worse, gray was not gray but had a distinct blue cast, and white was not white but had a yellowish tinge. The problem is that that can not be so easily corrected, because one takes the blue a little down (in the menu under "Gain"), the gray indeed neutral, but the yellowness is the stronger. On the other hand, the backlight bleeding was better here, inasmuch as it is an IPS panel.
Eizo itself advertises the display with a "IPS panel", which was already in the past with other models so, but Eizo admitted at various models to a demand that it was in fact referring to PLS panels from Samsung, one wants the panels but IPS call because the customer knows the way and would otherwise be confused.
In reality, it is probably so that Eizo various panels used in one and the same model with serious differences. This is not surprising, for example, Apple installed in many laptops optional PLS Samsung or LG IPS. However, we then as a customer, as well as with the Apple notebooks, either good or bad luck, that you get either very good picture quality, or even just average.
And that's the real problem: If you're lucky, you (ie PLS) gets a very good monitor with a 5 year warranty, and all at a very good price. Almost too good, Eizo will probably make these copies no profit. This is also the reason, I suppose, why a "series dispersion" also cheaper IPS panels are installed, only with this, a lot cheaper to producing panels Eizo will probably make a profit.
Most customers will not notice. I've also only noticed when I had 2 copies are next to each other, namely a right PLS, and left one of the 6 IPS copies.
Of course, even with the IPS variant, the image quality is not bad, but just average. For the price fetched but then too bad, could be as a customer then equal access to the originals, so monitors from LG with the same panel, for 100 Euro less, partly for half of what Eizo calls here.

Addendum of 20/03/2013:
Meanwhile, the Eizo Customer Service has delivered an opinion and wrote the following:
"The EV2336W is not around screens for Bildbarbeitung or for color matching. It is merely Office displays. Therefore, the same series screens can differ."
An on-site replacement of substandard equipment, which could not be calibrated correctly, was rejected. So I change my rating to 1 star.
In the meantime, I have further investigated the issue. The inferior panels, the color temperature is completely wrong. If you select eg a factory-calibrated color temperature OSD (that is, according to Eizo set separately for each device, which is at least it looks that for each device actually the RGB Gain, depending on the color temperature is different), is the actually measured with a spectrometer temperature seriously wrong. In the "good" copies itself had the correct means of the RGB Gain in the inferior not, it was a red tint. In addition, it is striking that in the inferior panel a tick down in the Green-Gain completely pulls the image into the yellow, while the color temperature is minimal change in the "good" copies.
In this respect, quality and above all the allegations on the website of Eizo are concerning. Onsite exchange completely untrue. Eizo has nothing to like.
In addition, you should enjoy the reviews on the internet on that basis with caution. Most test sites get their monitors directly from Eizo, so I am assuming that here hand selected specimens with 'good' panels were sent, are the inferior panels actually arrive mainly in the sale.

Addendum of 28/03/2013:
After I had received in the meantime, again contact with the support of Eizo to obtain a definitive opinion on whether Eizo will replace the monitor, I received a reply, the Eizo wrote, you would replace the device only "under certain circumstances". When I inquired as to what circumstances should be this, I received no further response.
One must therefore assume that the promised warranty of 5 years does not exist. I will therefore buy in future no further monitors from Eizo more. Other manufacturers are at least as honest, that they offer at the beginning only 1 or 2 years warranty, but then actually comply.
