Dual Monitors

To profile two monitors, two graphic cards or a dual monitor card with two graphic chips and output signals are required. Additionally the right graphic card driver needs to be installed.

Please note, the monitor profiling process in i1Match supports two steps: the first step is the monitor calibration, which stores an individual gamma table in the graphic card. The second step is the profile generation, which stores an individual ICC monitor profile as current system profile in the control panel "Display". If you have a dual monitor card with one graphic ship and two output signals, it is not possible to store an individual gamma table for each monitor (both monitors will be controlled by the same gamma table). But it is possible to set an individual ICC profile for each monitor in the system's control panel "Display". On dual monitor cards with one graphic chips you need to decide, which of the two monitors should be used for color critical work.
Here is an example for Windows XP, how to profile dual monitors. Before you can calibrate and profile both monitors you need to activate the "Multiple Monitor Features" on system level. Therefore please go to Start/Settings/control panel Display/Settings. In the appearing window select "Display 1" and activate the option "Use this device as primary monitor". Then select "Display 2" and check the option "Extend my Windows desktop onto this monitor". Close the control panel. Now you can calibrate and profile each monitor. Start i1Match and move the appearing main window on the monitor, which you want to profile. Perform the profiling process and save the profile. It should automatically be set as default system profile for each monitor. To check or assign your current monitor profiles, please go to control panel "Display/Settings". Then select "Display 1 or 2" and click on "Advanced". Select tab "Color Management". In the list below your created monitor profile should be set as default profile.
