There are 2 CG 30" Eizo models - CG301W with S-PVA, and new CG303W with P-IPS matrix. Personally I don't think that S-PVA type panel is a good idea for such a large display, so I wouldn't even consider CG301W, especially after having 21" CG Eizo with decent Hitachi advanced IPS type matrix. I'd also suggest to wait for NEC PA301W - it should be much cheaper than CG303W that costs a fortune, but should also be at least as good as Eizo (if not even better).
The new NEC PA271W is also a smart and economic alternative - it has 2540x1440px resolution, but is reasonably smaller, thinner, and it emits much less heat than my NEC 3090WQXi.
So after doing some research and reading, I decided to go for the NEC 3090 as my main monitor, and keep my Eizo Coloredge as a secondary monitor side by side. Yesterday, I set both monitors up. Each on their own separate video cards, calibrated both individually. NEC calibrated with the included puck, and the Eizo with the EyeOne pro. Since I do mostly print work, I set the white point to 5000k, and brightness to 120.
The Eizo has been a great monitor for the past 2 years, and dead-on accurate when compared to my prints.
Now that the 2 are side by side, when I view a 50% gray image they are completely off. The Eizo looks neutral, while the NEC has a weird greenish cast to it.
I've recalibrated each monitor numerous times, and they are still completely off from each other.
I wasnt expecting to get an exact match, since the NEC is a wide gamut monitor, but the gray balance should be MUCH closer than this.
Any suggestions why this is happening?
