I have the CG221, and it is not widescreen.
The sweetspot covers about 15% of the screen, where color is accurate. Beyond that, color and illumination are totally off. You need to move your image around to get accurate color and illumination on a specific spot; otherwise you cannot be sure if the magenta hue on the left side of your sky is lens cast or the monitor.
When I bought it, this was the most expensive monitor on the market. This monitor was advertised as having been designed for color-critical graphic work, so color consistency and even illumination was implied. However, it is far worse in that respect than any widescreen monitor I have seen.
Notably, Eizo has apparently solved this defect in their new model, but it is forcing its customers to dish out another $5000 for a new monitor. No matter how you spin it, this is not fair business.
Thank you for your post. Forgive me for not publishing my full info on the net, but the name Babak will certainly ring a bell with the guys at Eizo Switzerland.
It may just be this particular affiliate, but these guys set a new standard in rudeness and bad service. When I made a warranty claim, they simply said they won't honor it because I did not buy the monitor from them -- in clear violation of the terms of the international warranty.
At the end of the day, though, it is Eizo that pays the price. So they need to do a better job of knowing their representatives.
