Hi Jim,
I calibrate all my monitors, including laptop screen, using a device and software called Spyder4Elite. This set-up takes me out of the equation of adding any subjectivity. The process starts by setting the monitor back to factory defaults and then it goes on from choosing colour temperatures, sensing the ambient lighting in the room your working from etc..
Another nice advantage is for multi-monitor set ups, you can drag across screens and get the same colour representations and from machine to machine.
