Eizo do not allow thrd-party access to their internal LUTs...
Most display manufacturers that do this do so because they 'know' what they do is not ideal, and so do not want their approach to calibration to be scrutinised by others...
If Eizo were to open up to use we would be very intereested in talking with them, as we have done with penta, and are in the process of doing with FSI.
The difference with Penta is LightSpace has direct access to the display calibration vai the ability to control the display (the display is its own pattern generator) and the LUTs genertaed in LightSpace can be directly loaded into the monitor.
As for questios 2, that really depends on your level of acceptance... Some have had good resuts with a hp Dreamcolor...
But, there are some very good IPS based LCD screen out now.
Really too many to test all of them, so I would start by looking for an IPS LCD screen, woth LED illumination - RGB if possible.
Then check the gamut and RGB separation.
Hope this helps.
