Calibrated screens not the same

    I am running 2 (early 08) Mac Pros in my studio but try as I might I can't get the two Eizo screens to look the same.

    1st MP is 2 x3.2GHz Quad Core with 32 GB Ram and ATI Radeon HD4870 connected via DVI to an Eizo CG211 (Coloredge display).

    2nd MP is 2 x 2.8 GHz Quad Core with14 GB Ram and NVIDIA GeForce 8800 GT connect via DVI to an Eizo S2231W (Flexscan display).

    The CG211 runs ColorNavigator, Eizo's in built calibration system, (described as hardware calibration) using a Datacolor Spyder 3 sensor.

    The S2231W does not have hardware calibration and uses the same sensor Datacolor Spyder 3 and Datacolor's owner software Spyder3Elite 4.0.2.

    I am pretty confident that I am running through the calibrations correctly. The ColorNavigator is idiot proof and I have created a similar target on the other machine Temp 6500K, Gamma 2.2, Brightness 90.

    The Spyder3Elite is bringing back consistent results, consistent with previous calibrations, but just not the same as the other screen.

    In general I would say that the FlexScan Spyder3Elite screen looks warmer (less blue) than the ColorEdge Screen.

    They are next to each other on a long workbench so are under fairly similar lighting conditions.

    I have spoken with Native Digital who sold me both screens, with Eizo and ColorData, but everyone is fairly unhelpful blaming each other's products and sometimes the graphics cards.

    Anyone got any thoughts on this? Am I wrong to expect the screens to look the same?

    Two different calibration methods + two different panel technologies (one is IPS and the other S-PVA) = two different results

    A few considerations:

    - The CG211 is a "Wide Gamut" display whereas the Flexscan probably is not.
    - IPS displays lean towards purple in the blacks, especially when seen from the side.
    - Some calibration applications allow calibrating for a neutral black point which may help (ColorNavigator does, but it's called differently if I remember correctly).
    - Generally I would use the same software for both screens. In your case you'd have to use the Spyder software for both because ColorNavigator likely won't work with the FlexScan. Or you try a 3rd party software like basiccolor display which is not too expensive. They have a demo that runs for 30 days free, so you might give it a try:

    I use this to calibrate a FlexScan PVA and a ColorEdge IPS sitting next to each other. So it can be done in a satisfiable manner. Don't forget to have both displays running for an hour or so before calibration or comparison, of course... :)
