Hi Daniele, please see the HDlink Pro thread first... then the Plasma thread... (not that you are using plasmas for grading)
As for the displays, I do not use any display with in-built calibration, as they have proven to rarely be accurate.
We are working with Penta on their calibration, where they will directly use LightSpace for full display calibration.
Alternatives are to use a good external LUT box, but that can get expensive - Davio and Pluto are the ones that really do work, and we are working with the manufacturers of the eeColor box to get that accurately functional too.
I'm also not a fan of OLEDs as they do not represent what the final image will be viewed on...
