Hi there, I currently have a 24" Dell connected via DVI. I own an Eye1 Display LT calibrator which always frustrated me because with my Dell it never seemed to give consistent results. Even after back to back calibrations you could clearly see different results. Further, because I'm connected DVI I presume, I was never able to control contrast during the calibration process. I need to upgrade and will use my dell as a 2nd monitor. I want a 27" or possible 30" if it's affordable enough. I would like to not spend more than $1000. What are other professionals using these days?
