Hi, I think I found some minor issues in the online documentation: http://argyllcms.com/doc/instruments.html The following colorimeter doesn't have a hyperlink at the top of the document (while others do): i1 DisplayPro and ColorMunki Display colorimeters (i1 Display 3) Also the ColorHug link at the top of the document links to the ColorHug website, instead of the bottom of the document like for other colorimeters. At the bottom of the document there is an entry for the ColorHug, though it written with a typo a couple of times as ColoHug. Regards, Pascal de Bruijn
