Dear Rick, I have not been able to get basICColor Display 4 to communicate with the internal LUTs of my PA241. I gathered that the European version does but can't be sold in the US :( Roger -----Original Message----- From: colorsync-users-bounces+graxx=videotron.ca@lists.apple.com [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of Rick Hatmaker Sent: August-10-11 2:31 PM To: Ken Fleisher Cc: ColorSync Users Mailing List Subject: Re: NEC PA271W Hey Ken: NEC has 2 software options that will work: SpectraView and Multiprofiler. SpectraView will use actual measurements from your calibrator, MultiProfiler will use factory data. MultiProfiler is free. And as Andrew mentioned SpectraView is $89 from NEC's website. You might also look at basICColor Display v4, which will also communicate with the internal graphics, and is the core product for SpectraView versions used in Europe. Rick Hatmaker CHROMiX, Inc.
