Well, there is not much in depth information. But this is a fair description of what is going on:Kristian Jörg wrote:As I understand it CP is measuring each meter individually and attaching individual calibration profiles to every "PRO" unit. They charge about £60 for it.That's pretty vague. What sort of profiles ? What information do they contain ?

Hmm, one of their selling points (CP) is that the meter has very stable readings, even in very low light. Maybe they are reading several measurements and getting an average?When you say the DTP94 is better for refresh displays you get me a bit confused. I will be calibrating refreshing displays only. I.e a plasma TV, a PC monitor with led backlight and another with a PVA display (for photo editing) and a Home Theater LED based projector. Are you saying the i1d3 is not a good option for these displays? Or do you by refreshing displays mean CRTs?Anything with a non-constant light output is more subject to variations due to the fact that the i1d3 isn't capable of detecting or synchronising to the refresh period. The DTP94 is capable of this. It's easy enough to examine this - take the same reading over and over, and see how much it varies.
First question. Is the Chromapure PRO bundle with extra reference calibration really necessary in practice or is it just advertising fluff?Given the close comparison with the Discus, I get the impression that anything more that a standard i1d3 + display .edr/.ccss file is probably not buying much.
Do you provide standard calibration files with the i1d3 driver for Argyll?
