I have a Mac 27" desktop computer
Prior to Lion coming out I calibrated my Computer with the i1Display 2 colorimeter - Unfortunately this particular version is no longer compatible with Lion. I downloaded the update known as i1Profiler D2Lion Edition. There is a lack of information on best method to use this - . Thus my screen is never calibrated correctly. I tried support from x-Rite no joy as far as a fruitful response.
My thinking is looking to purchase the ColorMunki Display or the Spyder Color 4 Express. All I want is an easy quality colorimeter to calibrate my computer screen.
Being an Apple screen there one cannot adjust the brightness or luminance value
Anybody out there with experience on these matters
