We have found with many displays with 'self calibration' that the results are a lot below ideal.
We initially found that with Penta, and now FSI, and they both looked to adopt our calibration to improve their results.
Penta have that fully integrated now - FSI are just starting the required developed.
We are working with other display manufacturers to improve their calibration too,
With Eizo we have always viewed they display as good GUI displays, but not colour grading capable.
All profiling tests have shown the standard Eizo calibration to be non-optimal.
To calibrate an Eizo accurately you would need to turn off all internal calibration and use an external LUT box - eeColour for HDMI input for example, and profile anc calibrate with LightSpace CMS.
Hope this helps.
