Display colorsync profile remains unapplied?

[Christopher Hunt]

I've managed to log on to the actual computer, into the specific user  
involved, and obtain the ColorSync profile in use for each display. I  
ended up using the ColorSync utility to obtain this information.

According to the ColorSync utility both displays are using the same  
profile. Thus I think I have done everything now possible to ensure  
that the Mac is configured correctly.

However I've also learnt today that the "brighter" and different  
coloured display also has a 4500 ANSI bulb while the other one only  
has a 3000. :-) Apparently the 3000 one is also "on its way out".

So, I think all of my troubles have been associated with different  
bulbs and the age of the projectors in use. Thanks to all of you that  
have been part of this dialogue. I've definitely learnt a great deal  
about display management along the way so I hope that others will  
have found this useful.

Kind regards,
Christopher
