In fact, every PC was different. We invested in inexpensive Pantone Huey colorimeters and could show that our PC's matched the colors on the SGI workstations. The Huey had the ability to compensate for changes in ambient light. There don't appear to be Windows 7 drivers for the Huey, but there are linux drivers and associated utilities that seemed to work on a older laptop running Scientific Linux 7. In practice it wasn't able to get the laptop display to resemble the Apple displays we use these days, but I'd certainly try it if I relied on linux and had a decent display to work with. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@lists.fedoraproject.org Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
