i1 display pro question
not going to help you with your exact question but just wanted to share the fact that there is something called "calibration" and something called "profiling".
Calibration appears to be adjusting settings inside your screen's hardware (if the monitor supports it) - something they call LUT table. So you measure the screen output with the sensor and the measurements are than communicating back to the screen so screen can fix the output.
Than there is profiling - the screens is unable to do any changes to itself so to have right colors you are basically putting a filter on your existing screen to pull some values down or up.
Not sure if this helps but I just spent all Saturday trying to get the colors look right on my screen so I feel solidarity with you. Good article I went through: http://www.ronmartblog.com/2012/01/choosing-right-display-calibration.html
