Title: Re: Calibrating displays how often?
John,
My sense of your question is that it depends on who you are, your color matching requirements, what equipment you use (and how old it is) and how much money you are willing to spend. Some end-users believe that more is better. That is the more you calibrate your monitor the better chance you will have at keeping the same view on your monitor. This is a cost approach. While other end-users find a more moderate approach like calibrating every two or three week is just fine.
I take the moderate view.
But like I said, it depends.
My .02 Jim Rich.

I would be very interested in finding out more about how you did your testing and measurements. Hardware and software used and a brief summery of your test protocol.
Also was this done on anything besides the ACD? Your impression that this is an industry wide LCD issue and how might it also impact CRT calibration frequency?
By sharing your protocol others might be able to duplicate it with their displays and share those results.
The $64,000 question: Should users of specific devices or maybe even ALL displays be calibrating much more frequently than we all first thought?

We calibrate every 7 to 10 days because we did a lengthy experiment on the ACD and the iMacs, comparing new monitor measurement files daily to see what kind of drift was actually happening in our environment. We saw no real drift in the display's calibration up to about 8-9 days where we began to see the Delta E rise. We are after as much accuracy as possible in our softproofing workflows since expensive mag pages are on the line. We'd rather be on the safe side. I've learned never to listen to manufacturers reps and other expert prescriptions when it comes to color management. Every shop has to find out their own "best practices" in their own environment through diligent investigation and hands-on research.
