In these screen shots you show the corrections for the i1D3 are enabled, but for the CR-100 they are disabled. You are correcting only one of the meters with the CR-250.

The Cphw.dll file update may only be necessary for the 250. I am not even sure that it is. The CR drivers are finicky. I have reported this to them.

I ran a few quick measurements and the readings are now similar between the CR100 and i1D3, but RGB balance is still off.


Please notice, I used the same reference values from the CR250 to profile each meter.

Ok, I thought that the box was for enabling and disabling the CP corrections. I'll run a new session this weekend.


Thanks for informing Colorimetry Research about the drivers. I'll keep monitoring their site for updates.
