I have a dual monitor setup on my Ubuntu 12.04 LTS:
- the primary screen of my notebook Toshiba Tecra R850-11D
- my external monitor Samsung SyncMaster P2470HD
The external monitor has a much better image quality, since it uses its own ICC Profile (Default, SyncMaster), but the screen of my notebook doesn't use any ICC Profile.
What should I do and where could I get the appropriate ICC Profile for my Toshiba notebook in order to gain a much better quality of colors of my desktop environment?
