Is Calman Client 3 required for a local calibration i.e. the host computer? For some reason I can't get a display "found" unless I uninstall Calman RGB sans client, then install the client, then install Calman RGB and do a "repair". I would think that RGB would simply make an ICC profile and store it. I'm gettting some god awful results from Calman RGB with the X-Rite i1 and trying to track down what is going wrong. The display is an Acer XB280hk.
