I am in need of a calibration tool but do not want to spend $150 – $500. I tried DisplayCAL about 3 years ago maybe with an old Pantone huey. I guess it did the job although I am not sure I was really happy with it. I assumed the issue was more related to the huey than DisplayCAL – maybe age? Due to my budget constraints I am having to look at older calibration tools without Windows 10 support which brings me back to DisplayCAL. I am curious what everyone else’s experience is using older calibration tools with DisplayCAL? Is there a certain calibrator that DisplayCAL works best with and produces good results? I found a Spyder 3 Express but it doesn’t look much newer than my huey which in a round about way lead me to post this question.
